Excited to share our study of the latitudinal diversity gradient and how it may be modified by humans. Working with millions of bird observations across ~500 cities, we found that cities significantly flattened the diversity gradient for native birds in winter. 🧪 www.nature.com/articles/s44...

Cities alter the latitudinal diversity gradient of birds in North America - Nature Cities

Urbanization considerably modifies the latitudinal diversity gradient of birds in North America, with native species exhibiting a flatter gradient in cities compared to surrounding areas, particularly...

Please pass along: I’m recruiting PhD students to join our Macroecology Lab. We study physical ecology, macroecology, and biodiversity — spanning scaling, trait-based ecology, theory, comparative biology & ecoinformatics. Several avenues for funding. Please reach out if interested 🧪🌐🌾

‘Resilience’ has become a concept that is waved around like a magic wand in talking about responses to climate change Focussing on resilience can be unhelpful if it keeps the system in a failing state (undesirable resilience) We need to link resilience to system change rather than system inertia

🏺 An important archaeological discovery by our colleague @janturek.bsky.social & his team! Excavations near Chleby revealed an almost circular Neolithic causewayed enclosure, 230 m in diameter, with 12 gates, dating to around 4200 BC (Jordanów Culture).

The excavation of the Neolithic causewayed enclosure and an Iron Age house at Chleby is nearly completed. Students are cheering their achievement! Well done guys🤎👍🤎

🌐Local bird species richness is regulated—not by diversity-dependent extinctions, but by diversity-dependent colonization as communities approach equilibrium.

🐦 Is local species richness regulated, and if so, how? In a new paper in 🌍 GEB, our colleagues David Storch and @elbohdalkova.bsky.social show that diversity-dependent colonization regulates local richness, while extinction rates shape differences among communities. 🔗 doi.org/10.1111/geb....

Sad to hear of the passing of Robert Ricklefs - a giant of Ecology who simultaneously pushed forward big ideas at multiple biological levels yet took time for detailed natural history .. McGill does a nice job summarizing his impressive contributions 🌐🧪 dynamicecology.wordpress.com/2026/06/11/r...

Robert Ricklefs – in memoriam

Robert Ricklefs, a giant of ecology, passed away on Sunday. It is hard to overstate the extensive impact Bob had on the field. He was elected a member of the National Academy of Sciences in the US,…

Since January, I have gotten 8 desk rejections. Is this a new normal and a response to a deluge of AI-enabled papers journals are now receiving and/or dwindling availability of reviewers, or is our science not seen as novel enough (the latter I don't want to believe is true 😆)?
