🧪 Finally found where all the kool kidz ran off to 👋

Hi, I’m a conservationist that does science whenever I get the chance! Great to be here!

Current work is on snow leopards. I also post about primates, conservation tech, camera traps, AI & other stuff.

Here’s a paper we just published below 👇

Cool new #dronescience coming out of Vietnam, led by my colleague Hoang Trinh-Dinh.

authors.elsevier.com/a/1k2%7Ej1R%... (#OA for 50 days / DM for pdf)

Hoang used a drone to robustly survey the Critically Endangered Delacour’s langur in its extreme limestone home for the 1st time. (1/n)
Side-by-side drone images, comparing the colour RGB image and the thermal sensor image. Both have Delacour's langurs in them, but they are much more obvious in the thermal image.

This has been my experience too. When I run out of brainpower, I sometimes turn to LLMs. But then comes the endless back-and-forth with the thing to actually make the code work; I guess that’s the vibe coding part 🥺 I can’t imagine what this is doing to the skills of those newly learning coding…

"Vibe coding, does it work and if so, for whom?"

I did try using "AI" for coding. It turned the entire experience into continuous debugging session to fix extra subtle bugs. The fun and stimulating part was automated away, while the tedious parts that take the most time got worse and took longer.

Cool! Carnivores help mycorrhizal fungi to disperse.

Paper is here for those interested (although paywalled so I can’t actually read it): onlinelibrary.wiley.com/doi/10.1111/...

Truffle-spreading involves not one, but two meals: that of the animal which eats the truffle, and that of the animal which eats the animal that eats the truffle
To disperse their spores, truffles rely on animals eating other animals
It is a gruesome business

Love to see this: a women’s camera trapping group in the high mountains of Himachal Pradesh, western Himalaya. All power to them.

Exemplary data collection in the field shown as well, including proper testing of camera setup using “walk test” 😇

Alongside “AI colonialism”, the other big worry with this is that modelling results are never confronted with reality, they exist in some kind of desk-based bubble. All models are wrong, only some are useful. It’s by going out & touching the grass that we can sort the useful from the nonsensical.

#AI is transforming #ecology — but at what cost? A new #Nature piece warns that as models, drones & remote sensing boom, many scientists are spending less time outdoors (“I rarely get outside”). Are we losing essential natural-history insight? 🌿🤖

A drone’s-eye view of the South Gobi, Mongolia, at sunset. Home to our long-term study of snow leopards & the social-ecological system of ungulates, carnivores & livestock herders.

You might wonder if anything was living down there. But there are 20 snow leopards & 2000 ibex. Life finds a way! 🌏

I do over-share this quote, but it's just so apt for so many things wrong with the world (pretty timeless too).

We wrote the Strain on scientific publishing to highlight the problems of time & trust. With a fantastic group of co-authors, we present The Drain of Scientific Publishing:

a 🧵 1/n

Drain: arxiv.org/abs/2511.04820
Strain: direct.mit.edu/qss/article/...
Oligopoly: direct.mit.edu/qss/article/...
A table showing profit margins of major publishers. A snippet of text related to this table is below. 1. The four-fold drain 1.1 Money Currently, academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it. The dominant four are Elsevier, Springer Nature, Wiley and Taylor & Francis, which collectively generated over US$7.1 billion in revenue from journal publishing in 2024 alone, and over US$12 billion in profits between 2019 and 2024 (Table 1A). Their profit margins have always been over 30% in the last five years, and for the largest publisher (Elsevier) always over 37%. Against many comparators, across many sectors, scientific publishing is one of the most consistently profitable industries (Table S1). These financial arrangements make a substantial difference to science budgets. In 2024, 46% of Elsevier revenues and 53% of Taylor & Francis revenues were generated in North America, meaning that North American researchers were charged over US$2.27 billion by just two for-profit publishers. The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year. A figure detailing the drain on researcher time. 1. The four-fold drain 1.2 Time The number of papers published each year is growing faster than the scientific workforce, with the number of papers per researcher almost doubling between 1996 and 2022 (Figure 1A). This reflects the fact that publishers’ commercial desire to publish (sell) more material has aligned well with the competitive prestige culture in which publications help secure jobs, grants, promotions, and awards. To the extent that this growth is driven by a pressure for profit, rather than scholarly imperatives, it distorts the way researchers spend their time. The publishing system depends on unpaid reviewer labour, estimated to be over 130 million unpaid hours annually in 2020 alone (9). Researchers have complained about the demands of peer-review for decades, but the scale of the problem is now worse, with editors reporting widespread difficulties recruiting reviewers. The growth in publications involves not only the authors’ time, but that of academic editors and reviewers who are dealing with so many review demands. Even more seriously, the imperative to produce ever more articles reshapes the nature of scientific inquiry. Evidence across multiple fields shows that more papers result in ‘ossification’, not new ideas (10). It may seem paradoxical that more papers can slow progress until one considers how it affects researchers’ time. While rewards remain tied to volume, prestige, and impact of publications, researchers will be nudged away from riskier, local, interdisciplinary, and long-term work. The result is a treadmill of constant activity with limited progress whereas core scholarly practices – such as reading, reflecting and engaging with others’ contributions – is de-prioritized. What looks like productivity often masks intellectual exhaustion built on a demoralizing, narrowing scientific vision. A table of profit margins across industries. The section of text related to this table is below: 1. The four-fold drain 1.1 Money Currently, academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it. The dominant four are Elsevier, Springer Nature, Wiley and Taylor & Francis, which collectively generated over US$7.1 billion in revenue from journal publishing in 2024 alone, and over US$12 billion in profits between 2019 and 2024 (Table 1A).

The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year. The costs of inaction are plain: wasted public funds, lost researcher time, compromised scientific integrity and eroded public trust. Today, the system rewards commercial publishers first, and science second. Without bold action from the funders we risk continuing to pour resources into a system that prioritizes profit over the advancement of scientific knowledge.

Hey everyone, is there a literature (can be grey) discussing the ethics of using #generativeAI in #conservation and-or #ecology? I have to persuade some folks to consider the “darker” side of it and some authoritative/academic sources would really help. Thanks for any links.

✅Shared research objectives
✅Indigenous data sovereignty
✅Credit sharing
✅Respect & humility (“I didn’t “discover” anything”)

I find it’s helpful to always start from the premise:

“All models are wrong, but some are useful” (Box, 1979)

Editors & reviewers -

an ecological model can never be a complete representation of a system

they are simplifications, useful for exploring specific questions

Important reflections on the power dynamics in large-scale syntheses of ecological data. Many of them perpetuate colonial structures.

An example that comes to mind is Google & Wildlife Insights, who used camera trap data to publish the SpeciesNet algorithm, with no credit given to field researchers

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n
Abstract: Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media. For these collective blunders, we now regret our involvement or apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not considered a valid position to reject AI technologies in our teaching and research. This is why in June 2025, we co-authored an Open Letter calling on our employers to reverse and rethink their stance on uncritically adopting AI technologies. In this position piece, we expound on why universities must take their role seriously toa) counter the technology industry’s marketing, hype, and harm; and to b) safeguard higher education, critical thinking, expertise, academic freedom, and scientific integrity. We include pointers to relevant work to further inform our colleagues. Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI (black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf. Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al. 2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA). Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

*Seeing double*

Nope, these images are not the same, or even from the same image sequence! They were taken 23 days apart, with raging snow storms & high winds between them.

#Snowleopards are creatures of habit, regularly coming back to the same tiny patches of ground to see who's been around.

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.
