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

Update: The academic flight from Twitter is now complete and appears permanent. April 2023, after the pandemic research surge, we recorded 2,234,307 posts sharing research on Twitter. As of April this year, "X" had 896,741 posts about research. That's a 60% drop in traffic.

Graph showing cumulative research sharing across platforms, including Twitter - April 2023Graph of April 2026 cumulative research sharing including "X". One third of what it was.

🚨Update: Our analysis of global APC expenditure has now been expanded to cover more publishers (7 -> 14) and more years (2019-2025). We estimate $15B in APCs paid over seven years, $3.7B in 2025 alone. Elsevier crosses the $1B threshold by itself in 2025. arxiv.org/abs/2608.16322 #ScholComm

🚨 Preprint! We combine our recent open dataset of #APC prices with the article counts per journal-year from #OpenAlex to estimate how much the academic community has paid in APCs over the last 5 years. A. $8.349 billion ($8.968 B in 2023 USD) $2.5B in 2023 alone. arxiv.org/abs/2407.16551 #metasci

I don’t think there’s ever been a clearer example of the British media bullying someone, who was so clearly vulnerable, to death so shamelessly in my lifetime for engagement and clicks And now we’ll have to watch the people that did it claim they’re shocked, and horrified Revolting

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

Ecological novelty induced by climate change - Nature Climate Change

The authors review ecological novelty—ecological situations with no precedent—arising from climate change. They discuss ecological novelty due to direct and indirect effects of climate change, and due...

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 · 5mo 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/...
