Looking for a postdoc/job! Research on diversity dynamics in novel ecosystems. Palaeo/macro/marine-ecology Also chatting craft beer, tabletop gaming, and open/ethical science. Views mine. He/him. 🐚🐟🌍

Using satellite observations from 2001–2024, we assessed how vegetation greening relates to N deposition alongside climate change, fire and human land-use change. Across most major climate zones and ecosystem types, nitrogen deposition showed the strongest association with greening. (2/5)

Figure showing positive association between N deposition and increases in green plant biomass across biomes. Models for changes in EVI as a function of N deposition were fitted for a variety of subsets separately, including Köppen–Geiger climatic regions (A)–(B) and aggregated biomes based on the functional biomes of Higgins et al. (2016) (C)–(D). (A) Coefficient estimates for each Köppen–Geiger climatic region separately. Error bars indicate the 95% confidence interval; (B) spatial distribution of climatic regions; (C) coefficient estimates for aggregated biomes separately; (D) spatial distribution of aggregated biomes. All variables have been scaled and centered for modeling. Variables were considered significant when the 95% confidence interval of the coefficient estimate did not overlap zero. A positive coefficient estimate indicates a positive relationship between the respective predictor variable and the response.

There is ample evidence that climate change is altering ecosystems into novel configurations. Chuffed to have been part of this new paper on how climate change induces ecological novelty, and how we can possibly adapt and mitigate the impacts. www.nature.com/articles/s41558-026-02697-8

Was really cool to be part of data collection effort of this study - which involved a huge effort and authors from all continents. Really important results for moving forward with open science too - read for details and advice! And thanks @nhcooper123.bsky.social for leading us all with patience 🙏🏼

Excited to share our new paper in @methodsinecoevol.bsky.social on data and code archiving at @britishecologicalsociety.org journals. TL;DR: Data archiving rates are high, code archiving rates are low, documentation needs to be improved! besjournals.onlinelibrary.wiley.com/doi/full/10.....

Reptiles with longer Wikipedia pages tend to be bigger. The relationship is a power law with exponent = 0.85. I guess humans really like writing about big lizards? The longest article is the Komodo Dragon.

Check out our new letter in Conservation Biology where we argue that (re-)introduced large herbivores are often wrongly framed as harmful because herbivory is automatically equated with ecological damage - overlooking their potential to restore biodiversity and ecosystem functioning.

Matt Kerr@mattkerr.bsky.social · 3mo ago

Herbivory is a fundamental ecological process; treating it as harm (like recent work has suggested) misinforms conservation decisions about introduced herbivores. conbio.onlinelibrary.wiley.com/doi/10.1111/...

And when you point this out the response is usually “leave people alone” or “mind your own business,” as though an industry explicitly designed to shape aesthetics doesn’t impact people. Extreme thinness is framed as an individual choice and not something that shapes, or is shaped by, pop culture.

Hollywood has developed a collective eating disorder based around a particular set of medications that almost no one in Hollywood needs, and the result is that a lot of beautiful people now look like they're dying, and culturally, this is going to be so phenomenally destructive, esp for young ppl.

I’m super happy to share that we’re looking for a PhD student to join us! It’s an exciting project and a great opportunity to work together on big questions about biodiversity and human impacts. Come work with us! and please share with people who might be interested 👉 m.refline.ch/673277/1356/...

What do I think about the giant Cretaceous octopuses? - First that I'm delighted people are asking me 😁 - Second that WOW! Scientists used an amazing technique to discover HUGE fossil cephalopod beaks! 🤩 - Third that OH BOY do I have questions...🧵🧪🐙 www.science.org/doi/10.1126/...

Earliest octopuses were giant top predators in Cretaceous oceans

Top predators drive changes in ecosystem structure. For the last ~370 million years, large-sized vertebrates have dominated the apex of the marine food chain, while invertebrates have served as smalle...
