    1. Although some of the EverForecast species models provide output on a daily time scale, water managers and scientists in the Everglades typically evaluate hydrologic conditions and make recommendations on a weekly to monthly time scale. To target managers’ needs, we summarized EverForecast outputs on a biweekly (14 day) time step.

Noël Mamère, der bisher erfolgreichste grüne Präsidentschaftskandidat Frankreichs, und der junge Aktivist Achraf Manar stellen im Interview fest, dass die politische Ökologie im Gegensatz zu den angepassten Teilen der grünen Parteien keinen sanften Übergang" verspricht. Die globale Erhitzung trifft vor allem die Verwundbarsten der Gesellschaft, für die sich die ökologische Bewegung deshalb vor allem engagieren muss. Beide verteidigen den zivilen Ungehorsam und stellen fest, dass die ökologische Bewegung zunehmend zum Sündenbock für die Folgen der Klimakrise gemacht wird. https://www.liberation.fr/environnement/noel-mamere-et-achraf-manar-il-faut-que-celles-et-ceux-qui-subissent-les-crises-soient-au-coeur-des-prises-de-decision-20240209_QYUABTHUTBB3DCL2LXBBKLK4ZI/

      • title: Why conservation biology can benefit from sensory ecology

      • author Davide M. Dominoni et al.
      • date: Mar. 2020
      • abstract
        • Global expansion of human activities is associated with the introduction of novel stimuli, such as
          • anthropogenic noise,
          • artificial lights and
          • chemical agents.
        • Progress in documenting the ecological effects of sensory pollutants is weakened by sparse knowledge of the mechanisms underlying these effects.
        • This severely limits our capacity to devise mitigation measures.
        • Here,we integrate knowledge of animal
          • sensory ecology,
          • physiology and
          • life history
        • to articulate three perceptual mechanisms—
          • masking,
          • distracting and
          • misleading
        • that clearly explain how and why anthropogenic sensory pollutants impact organisms.
        • We then
          • link these three mechanisms to ecological consequences and
          • discuss their implications for conservation.
        • We argue that this framework can reveal the presence of ‘sensory danger zones’, hotspots of conservation concern
          • where sensory pollutants overlap in space and time with an organism’s activity, and
          • foster development of strategic interventions to mitigate the impact of sensory pollutants.
        • Future research that applies this framework will provide critical insight to preserve the natural sensory world.
    1. The field of sensory ecology is based on studying the sensory systems of animals in order to understand what they perceive in their environments and how that is going to affect their interactions with that environment (Dangles et al. 2009).

      • abstract
        • Sensory organs represent the interface between
          • the central nervous system of organisms and
          • the environment in which they live.
        • To date, we still lack a true integration of
          • ecological and
          • evolutionary perspectives
        • in our understanding of many sensory systems.
        • We argue that scientists working in sensory ecology should expand the bridge between
          • sensory and
          • evolutionary biology, and,
        • in working toward this goal, we advocate a combination of
          • the experimental rigor of the sensory physiologist with

          • William Rees
          • Rex Weyler
          • Nora Bateson
      • Reflections Overall,

        • an insightful discussion on the polycrisis and
        • reflections on what is in store for civilization.
      • There is consensus that
        • what we are experiencing has been decades in the making and
        • the solutions-oriented approach to solving problems has only treated the symptoms and indeed has made things worse.
      • There is a strong undercurrent of the emptiness in nature
      • Rex

        • emphasized the folly of human exceptionalism that has been socially normalized and which
        • continues to create the major separation that fuels the polycrisis.
        • Not recognizing that we are nature, not recognizing our animal nature
        • we look upon nature with an attitude of controlling nature, rather than flowing with her.
        • advocated Taoism as a more consistent way to frame nature rather than the reductionist, control methodology that separates us from nature.
      • Nora's perspective is the folly of abstraction that generates fixed preconceptions of aspects of nature that we then reify.

        • The fixed preconceptions are solidified but they are an oversimplified version of reality,
        • and that oversimplification leads to actualizing the cliche"a little knowledge is dangerous" into civilization
        • in other words, the continuous manufacture of progress traps.
      • William sees our impending crash as not only inevitable, but natural.

        • In this, he concurs with Rex's perspective.
        • Human beings are simply another species and like them,
          • we are susceptible to population explosions when negative feedbacks are removed,
          • which can lead to nature self-correcting with mass dieoff when resources are overconsumed.

          • I think this is also part of our sense of who we are as humans, as ourselves,
          • and the idea of the self, the individual, and even the humans as this individual species,
          • these divisions are arbitrary.
          • I don't stop at my skin.
          • I'm breathing air.
          • I'm drinking the water.
          • I'm eating food.
          • I'm eating an apple.
          • When I eat an apple, when do the molecules of the apple become me? -When I'm chewing it in my mouth?
            • when it's in my stomach?
            • when my system has broken down the nutrients?
            • when is that point that nitrogen molecule becomes me versus the apple?
          • I would propose that apple is me when it's growing on the tree.
          • I think of the blossoms of the tree and the bees.
            • The blossoms of the tree,
            • the tree can't reproduce without the bees.
            • So is the bee part of the tree?
            • The bee is part of the reproductive system of the tree.
            • So the bee is part of the tree,
            • the tree is part of the bee.
            • The bee needs the tree.
            • The tree needs the bee.
          • This is just one simple relationship,
            • but it's not simple at all because
              • the bee needs a lot of other things,
              • and the tree needs a lot of other things.
              • And the mycelium and the soil.
          • We talk about a tree and the soil and the atmosphere and the bee as if they're all separate things.
          • And that's convenient because our language has nouns that mean certain things.
          • So we want to talk about trees.
          • It's nice to have a word for tree,
            • but we get it in our head that the tree is separate from the soil,
            • which is separate from the atmosphere,
            • which is separate from the bee.
          • And I'm saying no, those divisions are indeed somewhat arbitrary,
          • but we use them for convenience.
          • But the soil's not the soil without the relationship with the tree
            • and the tree's not the tree without the relationship with the soil and the atmosphere.
            • And the atmosphere is not the atmosphere without the relationshi to the tree, to the bee, to me and the soil.
          • So to me that's the essence of ecology.
          • And that we have to expand this sense of self,
            • individual self as well as
            • the species of humans.
        • And this isolated self, I think is a socially reinforced construct, - but we get sucked into it.
          • And we talk about relationships in ecology and we talk about the value of all living things,
          • but in our actions we come back to the individual self.
    2. So something about our   process is completely wrong. Something about our  understanding of ecology is completely wrong.   But for me, I look back at, for example,  the Daoists. To me, the Daoists understood   very deeply the complexity. Daoism really starts  with just accepting the mystery and the complexity   00:19:33 of the world and not trying to necessarily  explain it all, and then to pattern behavior   after these natural processes

      • comment
        • the Zen mindfulness practices demonstrated in the rest of the paper depend on one assumption
          • that the scientific narrative employed are within the salience landscape of the reader
        • if they are not aligned to these narratives (ie, if they are religious fundamentalists) then these practices will fail to be effective
        • this suggests that we may need to appeal to an even more fundamental human quality that IS shared by all of us, the creation of narratives
    2. We will act to save “life on this planet” only if we recognize at a deep level that our “self” includes all beings. We need to recognize and feel at a deep level that ultimately we are not biologists trying to save other species. Rather, we are one emergence of life on this planet trying to save itself.

    1. information ecology research mainly focuses on information ecosystems, information ecology in e-commerce, and information ecology in a network.
    2. information ecology is an emerging field with vigorous development in recent years, and information ecology research is a multi-disciplinary subject.
    1. goal perspective, information ecologies have been designed to increase engagement with collaborative tasks (Price & Pontual-Falcão, 2011), enhance whole classroom learning (Rick, 2009), boost creative problem solving (Hilliges et al., 2007), support product design conversations (Bardill, Griffiths, Jones, & Fields, 2010), and coordinate complex collaborative working (Huang, Mynatt, & Trimble, 2006).

      Two different perspectives on information ecology: user and goal

    2. Information ecology was defined by Nardi and O’Day (1999) to be “a system of people, practices, values, and technologies in a particular local environment” (p. 49).
    3. the design and integration of new technologies in learning activities cannot be studied independently of the classroom environment, less attention has been paid in learning environments

      Designing new learning technology is not always the best solution without paying attention to its learning environment.

    4. indicate that distributed cognition considers a collaborative activity taking place across individuals, artefacts and internal or external representations, as one cognitive system.
    5. How the information ecology allows the design group to coordinate their actions? How awareness is distributed within the group when working with multiple technologies? How each one of the technologies in the ecology supports coordination and collaboration of learning activities?
    6. an “information ecology” is a local environment enriched with multiple heterogeneous technologies, such as personal computers, handheld devices, interactive screens, which are interlinked as a unified system.
    7. cognition cannot be tamed within the boundaries of an individual, but researchers should expand the unit of analysis to include the surrounding environment.

    1. With few exceptions, most market democracies have recovered from the 2008 financial crisis. But the public has not recovered from the shock of watching supposed experts and politicians, the people who posed as the wise pilots of our prosperity, sound and act totally clueless while the economy burned. In the past, when the elites controlled the flow of information, the financial collapse might have been portrayed as a sort of natural disaster, a tragedy we should unify around our leadership to overcome. By 2008, that was already impossible. The networked public perceived the crisis (rightly, I think) as a failure of government and of the expert elites.

      Martin Gurri argues that had the financial crisis of 2008 happened in the 20th century, the elites, through their control of the flow of information, might have portrayed it as a natural disaster we should rally around our leadership to overcome. But with the advent of the internet, we got the "networked public", and the elites and government lost their monopoly on information.

    1. I installed a roof rack on my car recently, it's always full of bugs. The car itself is almost bug free.It's possible that modern aerodynamic cars are better at avoiding bugs than old cars, although I don't know if this explains the whole difference. reply parent bregma () 2 minutes ago on I think it does. I don't remember the bugs being nearly so bad back in the 1960s and 1970s as they are now where I live, but I never have to clean off the windshield of my car. When I was a youth we would fight for the privilege of squeegeeing the windshield at every gas fill-up. Now, it's hard to go out without drawing a cloud and even the dog wants to stay inside in the summer.I suspect automobile aerodynamics play a bigger role in the windscreen index reduction than ecological destruction does.

    1. I think you're coming from an anthroprocentric perspective and behaviorialist paradigm, where natural processes are understood in the lens of humans and human actions ("The focus is on the efficient production of useful goods in ways that require minimal maintenance by letting other creatures do all the work for you"), and the reason someone does something is because it benefits themselves or other humans ("without that core benefit nobody could do it even if they wanted to and have a viable farm").The ethical principle of "Fair Share" isn't just about the yields the land owner has, but also the yields other inhabitants of an ecology have. For people who are motivated by stewardship, for example, humans obtaining benefits is not elevated into its own thing. As an example, some of the Native tribes would say something along the lines that when you plant, one is for the plants, one is for the animals, one is for the birds, one is for us. It is certainly not about maximizing production efficiencies for the benefit of humans alone.That motivation and attitude shapes the way someone views and experiences their life, and their place, and in turn shapes how we go about caring for land, caring for people, and fair share.I know I'm cheating here a bit. I'm using the work of Carol Sanford to identify world view and paradigm, and that way of thinking through these things are not spelled out in the original works of Mollison and Holmgren. Sanford's work on regenerative paradigms and living systems world view goes a long way towards sorting out the different ways people approach things in the permaculture community, and is generalizable more broadly than food systems.Regeneration is a characteristic exclusive to living systems. It's not something that can be approached from a world view that everything is a machine, or the paradigm that one can control behavior through incentives and disincentives. Only living systems can regenerate. It's the broader paradigm from which "your food (and other resources) produce themselves" comes from. Living systems are capable of growing and adapting on their own; they are nested -- so that is you and I, within larger living systems of family, community, organization, ecology. It is because of regeneration that "food and other resources produce themselves".My point in all of this is that there is a diversity of motivations and views, and the view that "without that core benefit nobody could do it even if they wanted to and have a viable farm" is not as universal as it sounds like. "The core reason to do permaculture is that your food (and other resources) produce themselves" might be your core reason, but it is not true it is the reason that everyone in the permaculture community applies permaculture.

    1. Erving Goffman, you may recall, was a mid-twentieth century sociologist, who, in The Presentation of the Self in Everyday Life, developed a dramaturgical model of human identity and social interactions. The basic idea is that we can understand social interactions by analogy to stage performance. When we’re “on stage,” we’re involved in the work of “impression management.” Which is to say that we carefully manage how we are perceived by controlling the impressions we’re giving off. (Incidentally, media theorist Joshua Meyrowitz usefully put Goffman’s work in conversation with McLuhan’s in No Sense of Place: The Impact of Electronic Media on Social Behavior, an underrated work of media theory published in 1986.)3

      Sacasas also makes reference to an article he wrote in which he made use of Goffman's theory to make sense of online experience

    1. In “Dark Ecology,” Morton writes that we must cultivate a “spirituality of care” toward the objects of the world—not just the likable parts but the frightening ones. Morton suggests that, instead of burying nuclear waste, we might store it aboveground, in a visible place, where we can learn to take more responsibility for it—perhaps even building an aesthetically interesting enclosure. The kind of care Morton envisions is as interested in piles of sulfur as in trees; it is concerned with both polar bears and circuit boards. Morton wants us to care for plutonium. At a minimum, Morton thinks that this kind of caring could cure us of the idea that we are in control; it might show us that we are part of a vast network of interpenetrating entities that come to know one another without dispelling their mystery. At a maximum, Morton seems to feel that this omnidirectional, uncanny form of care could help save the world.

      dark ecology is an honesty to looking at the role industrialization has terraformed our planet.

      Visions of Earth

      On Christmas Eve 1968, Bill Anders looked out his window and saw something no one had ever seen before. Against a pitch-black sky, framed by a bone-dead, mottled-gray landscape, hovered a hazy half-dome of swirling white and brilliant blue, the only bit of color anywhere in sight. It was a stark scene, a solitary figure floating in “a vast lonely expanse of nothing,” as one of his two companions described it, yet it overwhelmed them all with emotion, a kind of awe perhaps previously unfelt by anyone in history. “It was the most beautiful, heart-catching sight of my life,” one later recalled. Anders did what every sightseer does—he took a photograph. That quick snapshot became, in the words of biophysicist John Platt, “one of the most powerful images in the minds of men today.”

      The crew of Apollo 8—Anders, Frank Borman, and Jim Lovell—not only were the first people ever to leave orbit and the first to see the dark side of the moon but also were the first to witness Earth intact, not as a fragmentary arc of horizon but as a complete being, an entire world. “We came all this way to the Moon,” Anders later recalled, “and yet the most significant thing we’re seeing is our own home planet.”

A landscape — as a scene, landschap, ecosystem, and socio-political territory — is a material assembly of moving entities, a dynamic medium which changes in quality and structure through the aggregate movements or actions of the things that constitute it.

    1. At the global level none of the 20 targets have been fully achieved, though six targets have been partially achieved (Targets 9, 11, 16, 17, 19 and 20). Examining the 60 specific elements of the Aichi Biodiversity Targets, seven have been achieved and 38 show progress. Thirteen elements show no progress or indicate a move away from the target, and for two elements the level of progress is unknown. The table on the following pages provides an overview of the progress made towards each of the 20 Aichi Biodiversity Targets.

      +!!. So 0/20 achieved. 6 partially achieved. Of more granular items 7/60 and 38 show progress. 13 we have gone backward.

    1. A six-word California fire ecology primer: The state is in the hole. A seventy-word primer: We dug ourselves into a deep, dangerous fuel imbalance due to one simple fact. We live in a Mediterranean climate that’s designed to burn, and we’ve prevented it from burning anywhere close to enough for well over a hundred years. Now climate change has made it hotter and drier than ever before, and the fire we’ve been forestalling is going to happen, fast, whether we plan for it or not.

    1. We’re presently living through what feels like a remarkably turbulent time. In fact, we might be tempted to think that ours is a uniquely chaotic moment. Of course, most of us know that human beings have lived through more chaotic, violent, and calamitous times than ours. What is novel in our experience isn’t the depth of the health crisis or the scale of the protests, the economic volatility, or the political instability. What is novel is the information ecosystem in which all of this and more is unfolding. Most of us now have far greater access to information about the world, and we are—arguably, I grant—exposed to a far wider array of competing narratives attempting, without notable success, to make sense of it all. In short, it would appear that our basic sense-making technology, the narrative, is a bit glitchy, both failing to operate as we might expect and causing some issues of its own. You won’t be surprised to learn that I think Marshall McLuhan can be helpful here. While many have found McLuhan’s aphorism “the medium is the message” confounding, McLuhan actually offered a rather straightforward explanation. “The ‘message’ of any medium or technology,” McLuhan wrote, “is the change of scale or pace or pattern that it introduces into human affairs.” “The effects of technology do not occur at the level of opinions or concepts,” McLuhan added, “but alter sense ratios or patterns of perception steadily and without any resistance.”Digital media introduced a new scale, pace, and pattern to human communication, and, in this way, altered how the world is perceived. With regards to scale, we encounter an unprecedented amount of information about the world at large through digital media. With regards to pace, we encounter this information with previously unknown and unrelenting immediacy. And, with regards to pattern, we encounter it both in novel social contexts and in a form that bears greater resemblance to a database than a story.

    2. Such biosensors can reveal intriguing aspects of the environment and the physiology of the free-living soil S. meliloti before and during the establishment of nodulation, and they provide a nondestructive, spatially explicit method for examining rhizosphere soil chemical composition
    1. quantifying biogeochemical fluxes resulting from these reactions remains a challenge
    2. These tools provide insights into processes such as N uptake at the scale of individual root tips, allowing observation of plant–microbe interactions on scales at which they actually occur, instead of being masked by a whole‐core average

    1. Fear of humans as apex predators has landscape-scale impactsfrom mount ain lions to mice (2019)

      Apex predators such as large carnivores can have cascading, landscape-scale impacts across wild-life communities, which could result largely from the fear they inspire, although this has yet to be experimentally demonstrated.

      Humans have supplanted large carnivores as apex predators in many systems, and similarly pervasive impacts may now result from fear of the human ‘superpredator’.

      We conducted a landscape-scale playback experiment demonstrating that the sound of humans speaking generates a landscape of fear with pervasive effects across wildlife communities.

      • Large carnivores avoided human voices and moved more cautiously when hearing humans,
      • medium-sized carnivores became more elusive and reduced foraging.
      • Small mammals evidently benefited, increasing habitat use and foraging.

      Thus, just the sound of a predator can have landscape-scale effects at multiple trophic levels.

      Our results indicate that many of the globally observed impacts on wildlife attributed to anthropogenic activity may be explained by fear of humans.

    1. Labour is, in the first place, a process in which both man and Nature participate, and in which man of his own accord starts, regulates, and controls the material re-actions between himself and Nature

      The end of this formulation translates from the german, "Stoffwechsel [metabolism] mit der Natur".

      Contemporary ecological Marxists, such as John Bellamy Foster, cite this passage in support of claims that Marx's economic writings understood human relations to the environment in terms of what he called the ‘metabolism’ (Stoffwechsel) between nature and society.

      Thus, scholars such as Foster argue that Marx’s ideas offer an historical explanation for the ecological impact of capitalism on a planetary scale.

      Locating this metabolic relationship in capitalist practices of resource extraction, food production and waste, the consequences of capitalist production's intervention in the "material re-actions between himself and Nature" produce what has been variously characterized as metabolic rift or metabolic shift

    1. Extending this notion of material ecology, the quality of ecology in feminist interaction design integrates an aware-ness of design artifacts’ effects in their broadest contexts and awareness of the widest range of stakeholders through-out design reasoning, decision-making, and evaluation. It invites interaction designers to attend to the ways that de-sign artifacts in-the-world reflexively design us [79], as well as how design artifacts affect all stakeholders.

      Quality of ecology -- how artifacts impact the design process, technical systems that work together, and users identity

    2. Material ecology theory emphasizes the extent to which an artifact participates in a system of artifacts [73, 52]. This structural approach considers ways that relationships among artifacts determine their meaning in the system or ecology.

    1. This reflects a fundamental property of EDM in that forecast performance depends solely on the information content of the data rather than on how well assumed equations match reality.To clarify the concept of nonuniqueness, consider the canonical Lorenz attractor (SI Appendix, Fig. S1A). The behavior of this system is governed by three differential equations (SI Appendix, Eq. S1). However, the axes can be rotated to produce three new coordinates, x′, y′, and z′, and the equations rewritten in terms of these new coordinates, allowing the system to be described using either representation (x, y, and z or x′, y′, and z′) as well as mixed combinations (e.g., x, y, and z′). Thus, with an infinite number of ways to rotate the system, there are an unlimited number of “true variables” and “true models.” In the case of sockeye salmon, the similar performance of different models (SI Appendix, Table S4) does not mean that one or the other model is incorrect; instead, it reflects the fact that the environmental variables are indicators of the same general mechanism, and so different variable combinations can be equally informative for forecasting recruitment.Again, we emphasize that including a variable does not imply a direct causal link—variables in an EDM model improve forecasts because they are informative; it does not mean that the included variables are proximate causes. Importantly, the converse does not hold either: a variable could be causal and yet not appear in the multivariate EDM; this might occur when multiple stochastic drivers affect recruitment in an interdependent way, necessitating that a model include measurements of all of the drivers to account for their combined effect. For example, although none of the tested variables seem to improve forecasts for the Birkenhead stock (SI Appendix, Table S4), this does not mean that these sockeye salmon are insensitive to SST, river discharge, and the PDO. Rather, it suggests that the effect of these variables may be modulated by other factors not considered here.

      This distinction between direct causality and information content is a really useful perspective even beyond EDM.

    1. Fire, rainfall, and particularly extreme climatic events such as El Niño can, at times, outweigh the importance of biotic factors such as competition or predation, emphasizing the importance of resource pulses associated with disturbances.

      Huge surprise

    2. Subsequent research making use of ternary phase diagrams eventually showed that in small mammal communities trophic structure is strongly related to resource use.

    1. Narratives that describe time as uniform and evolving throughout history towards more accelerated states have also been critiqued for theirpotential to reinforce social inequalities (Sharma 2014) and for justifyingthe appropriation of natural resources in unsustainable ways (Bastian 2012).

    1. On the other hand, though much less likely, is the possibility of the gig economy becoming a long-term fixture of capitalism.

    1. social ecology formally emerged with the work of Murray Bookchin

      We should clarify that the term "social ecology" is not Bookchin's, but, at least according to Janet Biehl's Ecology or Catastrophe: The Life of Murray Bookchin, originated with E.A. Gutkind. In 1953, Gutkind authored Community and Environment: A Discourse on Social Ecology. Use of the term may go back even further.

    2. the critique of a thing is inherent in the alternative presented

      Posing alternatives to capitalism and the nation-state simultaneously: 1) asserts the inadequacy of those institutions (a "negative" critique), and 2) asserts the superiority of the alternative being posed (a "positive" critique).

    3. We refer to the plural

      From our perspective, we are seeking to develop a social ecological theory within a broader ecosocialist movement in which there is no privileged praxis, but a plurality of mutually reinforcing practical strategies.

      Already, we can see that "Libertarian Municipalist," dual power, revolutionary syndicalist, and prefigurative approaches can be taken. Often, the praxes that emerge from the broadly ecosocialist sphere start from a high degree of theoretical agreement, but diverge strategically and not antagonistically.

    4. About

      Greetings! Potemkin here (one of the primary authors), just getting the hang of this annotation system. It's open-source. I like the idea of using annotation to facilitate deeper discussion, and perhaps as a more civilized and precise method of commenting or interacting with a website. I think this can facilitate virtual study groups and other remote collaborations. Exciting stuff!

      Please annotate, comment on blog posts that are open for comments, and let's try to build a positive, supportive, open ecosocialist community dedicated to creating Better Worlds and Brighter Futures!

    1. tri-fold pamphlet created around 2007

      I attempted to keep some of the formatting of the original, but this was not very successful. There are no doubt better overviews of Esperanto out there, but I wanted to highlight the little information I could find at the time on Esperanto's radical history, particularly among anarchists.

      I still believe in the potential of Esperanto. It's very simple and accessible for working-class and impoverished people--taking little time and with an abundance of free resources--to learn. After that, a world of potential is opened, being able to speak with any other Esperantist the world over and sharing information in a universal way.

      To me, Esperanto has the potential to facilitate a truly international revolutionary movement and its use helps dissolve borders and embodies the humanistic, anarchistic, cosmopolitan idea of "unity-in-diversity."

    1. ‘Thedilemma, then, is that a right to information couldmake people worse off in terms of information.’’Elgesem then provides a contextual analysis of therole search engines play in the broader ‘‘informationecology’’ constituted by contemporary ICTs. Elgesemis able to connect the search engine dilemma withKant’s second formulation of the CategoricalImperative, ‘‘Act in such a way that you treathumanity, whether in your own person or in theperson of another, always at the same time as an endand never simply as a means.’’8Here, Elgeseminterprets Kant to mean that by ‘‘humanity,’’ Kantrefers to our ability to reason as the central propertythat makes us human. The simple point, as empha-sized in Kant’s famous example regarding lying, isthat failure to provide truthful information is a primeexample of violating the CI because false informationmakes it impossible for the recipient to exercise herrationality. By the same token, Elgesem argues that abiased search engine likewise makes it impossible forusers to exercise their rationality, and thus likewiserepresent violations of the CI.

    1. Feedback mechanisms provide stability such that ecosystems appear stable during some time frames but can abruptly shift to express new structures in others (9)

      We need to understand how frequently these kinds of change happen in order to understand the potential for forecasting and the best kinds of models for approaching it.

    1. We invite all scientists to endorse this global environmental article and engage with a new alliance concerned about global climate and environmental trends

    1. One of the primary uses of a model like this one is to improve the conversation between stakeholders and managers. The model can be valuable in helping managers and citizens arrive at realistic goals and to realize that there will be inherent risks associated with meeting those goals. For example, our analysis shows that reducing the probability of transmission by one half in five years using vaccination is not likely when we include uncertainty in the ability of managers to treat a targeted number of seronegative females. Forecasts suggested that there was virtually no chance of meeting that goal (Table 12). Similarly there was a 7% chance of reducing adult female seroprevalence below 40% using vaccination. We can nonetheless use this work to articulate what level of brucellosis suppression is feasible given current technology. For example, managers and stakeholders might agree that it is enough to be moving in the right direction with efforts to reduce risk of infection from brucellosis. In this case, a reasonable goal might be “Reduce the probability of exposure by 10% relative to the current median value.” The odds of meeting that goal using vaccination increased to 26%. With this less ambitious goal, vaccination increases the probability that the goal would be met relative to no action by a factor of only 1.4. This illustrates a fundamental trade-off in making management choices in the face of uncertainty: less ambitious goals are more likely to be met, but they offer smaller improvements in the probability of obtaining the desired outcome relative to no action.

      Great description of the value of forecasting models for improving conversations between stakeholders and managers in the development of goals and expectations of outcomes.

    2. We show that these uncertainties combine to assure that long-term predictions, e.g., 20 years in Peterson et al. (1991); 35 years in Ebinger et al. (2011); 30 years in Treanor et al. (2010) will be unreliable because credible intervals on forecasts expand rapidly with increases in the forecast horizon (Table 9). Long-range forecasts will include an enormous range of probable outcomes. This finding urges caution in making long-term forecasts with ecological models.

      Cautionary note on making long-term forecasts with ecological models due to decreased accuracy with forecast horizon. This issue is made clear through the proper inclusion of uncertainty in the models.

    3. Evaluation of alternatives proceeded in three steps. We first obtained the posterior process distribution of the state at some point in the future, given no action, and calculated the probability that the goal will be met (Fig. 3A). The no-action alternative can be considered a null model to which alternative actions can be compared. Next, we approximated the posterior process distribution at the same point in the future assuming that we have implemented an alternative for management and calculated the probability that the goal will be met (Fig. 3B). Finally, we calculated the ratio of the probability of meeting our goal by taking action over the probability if we take no action. This ratio quantifies the net effect of management (Fig. 3C) and permits statements such as “Taking the proposed action is five times more likely to reduce seroprevalence below 40% relative to taking no action.”This process for evaluating alternative actions explicitly incorporates uncertainties in the future state of the population in the presence and absence of management. A useful feature of this approach is that the weight of evidence for taking action diminishes as the uncertainty in forecasts increases. That is, increasing uncertainty in forecasts compresses the hatched area in Fig. 3C. This result encourages caution in taking action. Also useful is the inverse relationship between the absolute probability that a goal will be met by management and the probability that it will be met relative to taking no action. As the ambition of objectives increases (e.g., the dashed line in Fig. 3 moves to the left), the absolute probability that the management action will be achieved declines (the hatched area in Fig. 3B shrinks), but the probability of success relative to taking no action increases (the hatched area in Fig. 3C expands). This feature represents a fundamental trade-off in choosing goals and actions that are present in all management decisions: objectives that are not ambitious are easy to meet by applying management, but they might be met almost as easily by taking no action.

      This is an exemplar of how to use complex process oriented models to inform the value of management decisions.

    4. The model omits covariates describing weather conditions, e.g., drought severity, which have been included in other models of bison population dynamics in Yellowstone (Fuller et al. 2007a). We justify this omission because our central objective was to develop a forecasting model. We we use the term forecast to mean predictions of future states accompanied by coherent estimates of uncertainty arising from the failure of the model to represent all of the influences that shape the population's future trajectory.
      1. Another nice example of needing to make choices about what complexity to include in the model.
      2. An example of an explicit choice to avoid including environmental factors since they themselves would have to be forecast.
    5. The model is not spatially explicit. Although there is evidence that the population is made up of two different herds that spend their summers in the northern and central portions of Yellowstone National Park (Olexa and Gogan 2007), we justify our decision to treat the population without spatial structure as a first approximation of its behavior and because recent evidence suggests that substantial movement between herds occurs annually (Gates et al. 2005, Fuller et al. 2007, White and Wallen 2012).

      One of the things I really like about this paper is that it highlights that no matter how many statistical complexities are included in a model there are always more that could be. It isn't tractable to include them all so you choose the ones you think are most important based on available evidence and your professional judgement.

    1. Thus, predicting species responses to novel climates is problematic, because we often lack sufficient observational data to fully determine in which climates a species can or cannot grow (Figure 3). Fortunately, the no-analog problem only affects niche modeling when (1) the envelope of observed climates truncates a fundamental niche and (2) the direction of environmental change causes currently unobserved portions of a species' fundamental niche to open up (Figure 5). Species-level uncertainties accumulate at the community level owing to ecological interactions, so the composition and structure of communities in novel climate regimes will be difficult to predict. Increases in atmospheric CO2 should increase the temperature optimum for photosynthesis and reduce sensitivity to moisture stress (Sage and Coleman 2001), weakening the foundation for applying present empirical plant–climate relationships to predict species' responses to future climates. At worst, we may only be able to predict that many novel communities will emerge and surprises will occur. Mechanistic ecological models, such as dynamic global vegetation models (Cramer et al. 2001), are in principle better suited for predicting responses to novel climates. However, in practice, most such models include only a limited number of plant functional types (and so are not designed for modeling species-level responses), or they are partially parameterized using modern ecological observations (and thus may have limited predictive power in no-analog settings).

      Very nice summary of some of the challenges to using models of contemporary species distributions for forecasting changes in distribution.

    2. In eastern North America, the high pollen abundances of temperate tree taxa (Fraxinus, Ostrya/Carpinus, Ulmus) in these highly seasonal climates may be explained by their position at the edge of the current North American climate envelope (Williams et al. 2006; Figure 3). This pattern suggests that the fundamental niches for these taxa extend beyond the set of climates observed at present (Figure 3), so that these taxa may be able to sustain more seasonal regimes than exist anywhere today (eg Figure 1), as long as winter temperatures do not fall below the −40°C mean daily freezing limit for temperate trees (Sakai and Weiser 1973).

      Recognizing where species are relative to the observed climate range will be important for understanding their potential response to changes in climate. This information should be included when using distribution models to predict changes in species distributions. Ideally this information could be used in making point estimates, but at a minimum understanding its impact on uncertainty would be a step forward.

      This is an interesting move in terms of form. Hayles herself is the one who introduced the term "dance" and then immediately amends it parenthetically to comment that she prefers the term "complex ecology." I'm not sure why she chose to leave both of those thoughts in, but I like it.

    1. the movement of plants 13,.:, .. ,..i... 1• toward the sun.

      When I made my last post about the Gaia Hypothesis, I'd already read this part, but I only just now realized that the Daisyworld simulation is actually really relevant to this. It's a model of a planet that has only white and black daisies (high and low albedo, so one reflects light and cools the planet, and the other does the reverse), and how the two species can unintentionally create and preserve homeostasis on the planet simply by following the light.

    2. Shortly after this im-age was released, the modem environmentalist movement in the United States began

      James Lovelock's Gaia Hypothesis originated slightly before 1967, but he was working for NASA's Jet Propulsion Laboratory, so in many ways, he already was working off a mental image of the Earth seen from the outside.

      Sidenote, but I first encountered the Gaia Hypothesis because the game SimEarth (which is built around modeling and playing with the concept) had a whole essay about it bundled in the game. I was way too young to really grasp the game without blatantly cheating (which feels like a worrying allegory), but I really remember the essay, along with SimCity's hidden essays on urban design and the character of cities. I'm trying to think if any video game since the Sim series has had a similar connection to an academic discipline.

      We forget to take into account the undergrowth.

    1. Sachs Harbour

      Sachs Harbour is located in the Inuvik region of the Northwest Territories, Canada and is situated on the southwestern coast of Banks Island in the Inuvialuit Settlement Region. According to the 2011 census, the population was 112 people. The principle languages spoken in the town are Inuvialuktan and English. The economy is primarily based upon hunting and trapping, but tourism also plays a small role. Residents also engage in ice fishing- harvesting fish from the Amundsen Gulf and Beaufort Sea. Banks Island is ecologically significant for being home to the largest goose colony in North America and is home to three quarters of the world’s population of muskoxen. Barren-ground caribou and polar bears are also seen on the island. On April 26, 2006, the world’s first documented wild-born grizzly-polar bear hybrid was shot near the town. The town has a Visitor Reception Centre that presents the Aulavik National Park and Inuvialuit culture to visitors to the Banks island and serves as a center for community activities. The town is of historical significance for a number of ships sent out to the Arctic Bay by the British Admiralty to find the lost expedition of James Franklin that became trapped in the ice for three years and was abandoned by its crew. One ships primary investigator and captain was Robert McClure who was able to identify the fabled North West Passage- a waterway across the top of North America that would allow passage to Asia from Banks Island. Only few have made this passage since due to icy and dangerous waters, but as the earth warms there may be a day when this passage becomes common. Sachs Harbour is in the Arctic tundra climate zone, which is characterized by long and extremely cold winters. Since many of the activities of the residents in the community revolve aroundfishing hunting,and travel, many residents have considerable knowledge of weather conditions, permafrost, and erosion patterns. Because of climate changes in recent years, many local residents fear that their knowledge of weather patterns may not be as useful as the weather becomes harder to predict. Since the climate has been changing, the sea ice is breaking up earlier than usual taking seals farther south in the summer. Seals are a main food source for the town. Climate change is bringing many other changes to the island’s ecology as well; salmon appeared for the first time in nearby waters between 1999 and 2001, new species of birds are migrating- including robins and barn swallows, and more flies and mosquitos have been appearing. Additionally, there is estimated to be 4 to 12 billion barrels of commercially recoverable oil in the Beaufort Sea and between 13 and 63 trillion cubic feet of natural gas. As the climate continues to warm it will be easier to access these resources, which could potentially damage the ecology of the island if not managed properly.

    1. Dr. Ian McTaggart-Cowan

      Dr. Ian McTaggart-Cowan was a professor of zoology and Dean of graduate studies at the University of British Columbia (UBC), where he founded and lead the first university-based wildlife conservation department in Canada. Referred to as the "Father of Canadian Ecology,” he was one of the founders of the study of environmental ecology in Canada, and was appointed to the board of The Nature Trust of British Columbia by the Prime Minister of Canada, where he served as director for 33 years. Dr. McTaggart-Cowan graduated from UBC and completed his PhD at the University of California at Berkeley. Since then, he has received many awards and honors for his research and dedication to the research and conservation of wildlife in Canada. His accomplishments also include founding the National Research Council of Canada, serving as Chair of the Environmental Council of Canada, the inaugural and 19-year Chair of the Public Advisory Board of the BC Habitat Conservation Trust Fund Foundation, keystone member (and later Chair) of the Birds of British Columbia author team, chancellor of the University of Victoria, and advocate for whaling commissions in support of its prohibition.

      At UBC, Dr. McTaggart-Cowan oversaw the research of more than 100 students and continued to inspire generations of academics. During the 1950s and 1960s, he produced television nature programs on CBC (Canada Broadcasting Corporation) such as Fur and Feathers, The Living Seas, and The Web of Life that were aired internationally in hopes of inspiring the youth to advocate for conservation and its research. Dr. McTaggart-Cowan also had a strong political voice and convinced the Canadian government to hire professional wildlife biologists for the country’s wildlife programs.

    1. Comparison of ITCD algorithms is challenging when there are differences in study focus, study area, data applied, and accuracy assessment method used. Before 2005, the few studies that compared methods generally tested approaches on a common dataset.

      This difficulty in comparing algorithms (due to differences in forest type, location, and assessment strategy used for different algorithms) indicates a clear need for set of open data and centralized assessment to allow different methods to be competed against one another to determine the best routes forward.

      This kind of approach has been very successful in other image analysis problems (e.g., ImageNET).

      The National Ecological Observatory Network data seems ideal for doing something like this. Data is/will be available for a variety of different systems and with LiDAR, Hyperspectral, RGB, and field data for large numbers of plots.

    2. Additionally, it is often challenging to apply an algorithm developed in one forest type to another area.

      This difficulty of applying across forest types is central to the challenges of developing approaches that can be applied to continental scale data collection like that being conducted by NEON. Overcoming this challenge will likely require incorporating ecological information into models, not just the remote sensing, and determining how to choose and adjust different approaches to get the best delineations possible based on information about the forest type/location.

    1. We also did not allow different portions of our study area to respond to climate in different ways. Doing so would require spatially varying climate effects and a substantial increase in computational time. However, in future applications, it will be important to allow climate effects to vary over space to better capture reality. Conn et al. (2015) provide examples of how such spatiotemporal interactions can be included in abundance models. We might expect climate effects to interact with spatial covariates such as soil type, slope, and aspect.

      Interesting point about the potential importance of spatiotemporal interactions.

    2. To simulate equilibrium sagebrush cover under projected future climate, we applied average projected changes in precipitation and temperature to the observed climate time series. For each GCM and RCP scenario combination, we calculated average precipitation and temperature over the 1950–2000 time period and the 2050–2098 time period. We then calculated the absolute change in temperature between the two time periods (ΔT) and the proportional change in precipitation between the two time periods (ΔP) for each GCM and RCP scenario combination. Lastly, we applied ΔT and ΔP to the observed 28-year climate time series to generate a future climate time series for each GCM and RCP scenario combination. These generated climate time series were used to simulate equilibrium sagebrush cover.

      This is an interesting approach to forecasting future climate values with variation.

      1. Use GCMs to predict long-term change in climate condition
      2. Add this change to the observed time-series
      3. Simulate off of this adjusted time-series

      Given short-term variability may be important, that it is not the focus of the long-term GCM models, and that the goal here is modeling equilibrum (not transitional) dynamics, this seems like a nice compromise approach to capture both long-term and short-term variation in climate.

    3. Our process model (in Eq. (2)) includes a log transformation of the observations (log(yt − 1)). Thus, our model does not accommodate zeros. Fortunately, we had very few instances where pixels had 0% cover at time t − 1 (n = 47, which is 0.01% of the data set). Thus, we excluded those pixels from the model fitting process. However, when simulating the process, we needed to include possible transitions from zero to nonzero percent cover. We fit an intercept-only logistic model to estimate the probability of a pixel going from zero to nonzero cover: yi∼Bernoulli(μi)(8)logit(μi)=b0(9)where y is a vector of 0s and 1s corresponding to whether a pixel was colonized (>0% cover) or not (remains at 0% cover) and μi is the expected probability of colonization as a function of the mean probability of colonization (b0). We fit this simple model using the “glm” command in R (R Core Team 2014). For data sets in which zeros are more common and the colonization process more important, the same spatial statistical approach we used for our cover change model could be applied and covariates such as cover of neighboring cells could be included.

      This seems like a perfectly reasonable approach in this context. As models like this are scaled up to larger spatial extents the proportion of locations with zero abundance will increase and so generalizing the use of this approach will require a different approach to handling zeros.

    4. Our approach models interannual changes in plant cover as a function of seasonal climate variables. We used daily historic weather data for the center of our study site from the NASA Daymet data set (available online: http://daymet.ornl.gov/). The Daymet weather data are interpolated between coarse observation units and capture some spatial variation. We relied on weather data for the centroid of our study area.

      This seems to imply that only a single environmental time-series was used across all of the spatial locations. This is reasonable given the spatial extent of the data, but it will be necessary to allow location specific environmental time-series to allow this to be generalized to large spatial extents.

    5. Because SDMs typically rely on occurrence data, their projections of habitat suitability or probability of occurrence provide little information on the future states of populations in the core of their range—areas where a species exists now and is expected to persist in the future (Ehrlén and Morris 2015).

      The fact that most species distribution models treat locations within a species range as being of equivalent quality for the species regardless of whether there are 2 or 2000 individuals of that species is a core weakness of the occupancy based approach to modeling these problems. Approaches, like those in this paper, that attempt to address this weakness are really valuable.

    1. Our abilities to make observations are limited to a small range of space and time scales (8), limiting our capacity for understanding ecosystems and forecasting how they will respond to local and global change.

      Our abilities to manage natural systems are also typically limited to a small range of space and time scales.

    2. A range of information sources, which can include models, is used to develop alternative plausible trajectories of ecosystems; uncertainties about the future are represented by the range of conditions captured by the ensemble of scenarios. In contrast, forecasts narrowly limit uncertainties to those associated with a single potential outcome that is assumed to be predictable

      This strong distinction between "forecasts" and "scenarios" seems like a rather arbitrary distinction on the surface. There are forecasting approaches that attempt to account for uncertainty in a broad array of things including uncertainty in the generating model. Many of the examples in Principles of Forecasting by J. Scott Armstrong are what would be described as "scenario" based approaches here. Likewise some of the approaches employed by forecasters in Superforecasting by Tetlock & Gardner involve developing a range of scenarios.

      Scenarios in general need to have a reasonable probability of occurrence to be usefully included in decision making. So at least at some minimum threshold it a probability is being associated with scenarios. Going one step further and assigning a probability to each member of a set of scenarios would result in a probabilistic forecast.

      In short, it seems to me that scenario development is, in many cases, a kind of forecasting. It may involve large uncertainties and it may currently be associated with different kinds of decision making, like choosing management practices that are robust to may possible models, but these can both be accomplished in other ways. Using language that implies that these are completely distinct approaches seems likely to cause confusion and unnecessary terminological debate.

    1. Practices in the field of financial investing provide a good analogy to the stance we suggest for ecological predictions. A great deal of money and effort has been used to model the best ways to maximize investment returns (certainly more money and effort than has been used to refine ecological predictions). Although this work has resulted in greatly increased understanding of economic systems, the risks and limitations of using sophisticated economic models to make investments has led more and more investors to instead use simple, safe index funds. Essentially this is the recognition that the models and expert opinions are of exceptionally little value in making accurate, long-range predictions in this field and that precautionary strategies are a far better alternative.

      The market is quite different from ecology in the sense that it responds to the predictions/forecasts that are made about it. The idea of the "efficient market" is one of the reasons why modeling the market is believed to be inherently difficult.

      It is also worth noting that investing in index funds is based on a simple model, that the market always increases at rates greater than inflation in the long run. In other words, an inclination towards index funds suggests that some aspects of the market are forecastable at some time-scales. Paying attention to what aspects of ecological systems are less susceptible to surprises (and at what scales) would be a useful route forward.

    2. First, major surprises are commonplace in the experience of field ecologists.

      The validity of this statement depends on what is meant by "commonplace". Given the question asked I think the results substantiate "major surprises occur at least once in most long-term studies". However, if the average long-term study involves thousands of observations/results then it's unclear to me if "at least one" surprise clearly supports "commonplace".

      The paper discusses this point further down in the paragraph, but it is a really important point since one of the overall messages of the paper is that the prevalence of surprises makes prediction difficult.

    3. After explaining our project and providing several well-known examples of ecological surprises, we asked the recipients whether or not they had encountered any such events in the course of their field studies

      I understand the need to explain what kind of "surprises" are being looked for. That said "providing several well-known examples of ecological surprises" immediately before asking about whether they are encountered also feels a bit like priming. Providing an even number of abstract examples that represent cases that both would and would not have been considered "surprises" seems less likely to bias the respondents.

      Also, the main question isn't really whether or not "surprises" occur, that is already taken as a given, it is how prevalent are they. It would have been interesting to include a question about what proportion of observations from the researchers site were considered to be surprising.

    1. Scenarios were initially developed by Herbert Kahn in response to the difficulty of creating accurate forecasts ( Kahn & Wiener 1967; May 1996 ). Kahn worked at the RAND Corporation, an independent research institute with close ties to the U.S. military. He produced forecasts based on several constructed scenarios of the future that differed in a few key assumptions ( Kahn & Wiener 1967 ). This approach to scenario planning was later elaborated upon at SRI International ( May 1996 ), a U.S. research institute, and at Shell Oil (  Wack 1985a, 1985b, Schwartz 1991; Van der Heijden 1996 ).

      Interesting information on the history of scenario based forecasting.

    2. Prediction means different things to different technical disciplines and to different people ( Sarewitz et al. 2000 ). A reasonable definition of an ecological prediction is the probability distribution of specified ecological variables at a specified time in the future, conditional on current conditions, specified assumptions about drivers, measured probability distributions of model parameters, and the measured probability that the model itself is correct ( Clark et al. 2001 ). A prediction is understood to be the best possible estimate of future conditions. The less sensitive the prediction is to drivers the better ( MacCracken 2001 ). Whereas scientists understand that predictions are conditional probabilistic statements, nonscientists often understand them as things that will happen no matter what they do ( Sarewitz et al. 2000; MacCracken 2001 ).In contrast to a prediction, a forecast is the best estimate from a particular method, model, or individual. The public and decision-makers generally understand that a forecast may or may not turn out to be true ( MacCracken 2001 ). Environmental scientists further distinguish projections, which may be heavily dependent on assumptions about drivers and may have unknown, imprecise, or unspecified probabilities. Projections lead to “if this, then that” statements ( MacCracken 2001 ).

      This distinction between "prediction" and "forecast" is not something I've generally seen in either the ecological forecasting literature or the forecasting literature more generally. This use is backed only by a citation to a guest editorial in a zine (think newsletter), so while I appreciate the need to be clear about uncertainty I don't think this treatment of the terminology is a particularly effective way to accomplish this.

    1. we used 2001–2009 fire counts detected by the Moderate Resolution Imaging Spectroradiometer (MODIS)

      The success of this model with only small amounts of training data is encouraging for other areas of ecology and environmental science where the available time-series may be short.

    2. Fire season severity, here defined as the sum of satellite-based active fire counts in a 9-month period centered at the peak fire month, depends on multiple parameters that influence fuel moisture levels and fire activity in addition to precipitation, including vapor pressure deficits, wind speeds, ignition sources, land use decisions, and the duration of the dry season. As a result, the relationship between FSS and SSTs may be more complex than the relationships between precipitation and SSTs described above.

      This recognition of additional factors that could influence fire, and the fact it more complex models using the same data may be able to indirectly use some of these influences is really valuable. It is, in effect, positing that latent variables associated with some of these causes may be associated with measurable aspects of SST.

    3. This is a nice example of chaining together separate pieces of knowledge to understand what form of forecasting model might be successful. Large scale climate phenomena -> variation in precipitation -> variation in fire season severity.

    1. My thoughts on Climatic Associations of British Species Distributions Show Good Transferability in Time but Low Predictive Accuracy for Range Change by Rapacciuolo et al. (2012).

    2. Whilst the consensus method we used provided the best predictions under AUC assessment – seemingly confirming its potential for reducing model-based uncertainty in SDM predictions [58], [59] – its accuracy to predict changes in occupancy was lower than most single models. As a result, we advocate great care when selecting the ensemble of models from which to derive consensus predictions; as previously discussed by Araújo et al. [21], models should be chosen based on aspects of their individual performance pertinent to the research question being addressed, and not on the assumption that more models are better.

      It's interesting that the ensembles perform best overall but more poorly for predicting changes in occupancy. It seems possible that ensembling multiple methods is basically resulting in a more static prediction, i.e., something closer to a naive baseline.

    3. Finally, by assuming the non-detection of a species to indicate absence from a given grid cell, we introduced an extra level of error into our models. This error depends on the probability of false absence given imperfect detection (i.e., the probability that a species was present but remained undetected in a given grid cell [73]): the higher this probability, the higher the risk of incorrectly quantifying species-climate relationships [73].

      This will be an ongoing challenge for species distribution modeling, because most of the data appropriate for these purposes is not collected in such a way as to allow the straightforward application of standard detection probability/occupancy models. This could potentially be addressed by developing models for detection probability based on species and habitat type. These models could be built on smaller/different datasets that include the required data for estimating detectability.

    4. an average 87% of grid squares maintaining the same occupancy status; similarly, all climatic variables were also highly correlated between time periods (ρ>0.85, p<0.001 for all variables). As a result, models providing a good fit to early distribution records can be expected to return a reasonable fit to more recent records (and vice versa), regardless of whether relevant predictors of range shift have actually been captured. Previous studies have warned against taking strong model performance on calibration data to indicate high predictive accuracy to a different time period [20], [24]–[26]; our results indicate that strong model performance in a different time period, as measured by widespread metrics, may not indicate high predictive accuracy either.

      This highlights the importance of comparing forecasts to baseline predictions to determine the skill of the forecast vs. the basic stability of the pattern.

    5. Most variation in the prediction accuracy of SDMs – as measured by AUC, sensitivity, CCRstable, CCRchanged – was among species within a higher taxon, whilst the choice of modelling framework was as important a factor in explaining variation in specificity (Table 4 and Table S4). The effect of major taxonomic group on the accuracy of forecasts was relatively small.

      This suggests that it will be difficult to know if a forecast for a particular species will be good or not, unless a model is developed that can predict which species will have what forecast qualities.

    6. The correct classification rate of grid squares that remained occupied or remained unoccupied (CCRstable) was fairly high (mean±s.d.  = 0.75±0.15), and did not covary with species’ observed proportional change in range size (Figure 3B). In contrast, the CCR of grid squares whose occupancy status changed between time periods (CCRchanged) was very low overall (0.51±0.14; guessing randomly would be expected to produce a mean of 0.5), with range expansions being slightly better predicted than range contractions (0.55±0.15 and 0.48±0.12, respectively; Figure 3C).

      This is a really important result and my favorite figure in this ms. For cells that changed occupancy status (e.g., a cell that has occupied at t_1 and was unoccupied at t_2) most models had about a 50% chance of getting the change right (i.e., a coin flip).

    7. The consensus method Mn(PA) produced the highest validation AUC values (Figure 1), generating good to excellent forecasts (AUC ≥0.80) for 60% of the 1823 species modelled.

      Simple unweighted ensembles performed best in this comparison of forecasts from SDMs for 1823 species.

    8. Quantifying the temporal transferability of SDMs by comparing the agreement between model predictions and observations for the predicted period using common metrics is not a sufficient test of whether models have actually captured relevant predictors of change. A single range-wide measure of prediction accuracy conflates accurately predicting species expansions and contractions to new areas with accurately predicting large parts of the distribution that have remained unchanged in time. Thus, to assess how well SDMs capture drivers of change in species distributions, we measured the agreement between observations and model predictions of each species’ (a) geographic range size in period t2, (b) overall change in geographic range size between time periods, and (c) grid square-level changes in occupancy status between time periods.

      This is arguably the single most important point in this paper. It is equivalent to comparing forecasts to simple baseline forecasts as is typically done in weather forecasting. In weather forecasting it is typical to talk about the "skill" of the forecast, which is how much better it does than a simple baseline. In this case the the baseline is a species range that doesn't move at all. This would be equivalent to a "naive" forecast in traditional time-series analysis since we only have a single previous point in time and the baseline is simply the prediction based on this value not changing.
