Our new paper led by Braeden Van Deynze shows insecticides are a leading driver of butterfly decline in the US Midwest, above climate and land use change. doi.org/10.1371/journa…

Living Planet Index "suffers from several mathematical and statistical issues, leading to a bias towards an apparent decrease even for balanced populations. The claim that vertebrate populations declined by 70% since 1970 is thus unsubstantiated". Source: communities.springernature.com/posts/the-livi…

Is fragmentation bad or good for biodiversity? Yes! We use a classical competition-colonization metacommunity model to show that fragmentation can increase or decrease diversity depending on the total amount of habitat in the landscape. iDiv Biodiversity Research Universität Halle (inaktiv) nature.com/articles/s4155…

🔍🌱 New research: Scientists reveal that the total habitat lost plays a crucial role in how fragmentation impacts biodiversity. This nuanced understanding challenges the binary view of fragmentation as purely good or bad. nature.com/articles/s4155… #biodiversity #idiv #research

This post is on behalf of our colleague and friend Priyanga Amarasekare, who is not on X and continues to endure disappointing and a draconian treatment by UCLA. She has asked us to share an update via this thread.

Was great having you visit iDiv Biodiversity Research! Looking forward to enlightening collaborations!

A recent study published in NatureEcoEvo highlights the delicate relationship between habitat loss, fragmentation and biodiversity. Jonathan Chase and colleagues show that the total amount of habitat lost is a key factor influencing how fragmentation affects #biodiversity. #idiv

The International Biogeography Society (TIBS) has relaunched its flagship OA scientific journal, Frontiers of Biogeography (FoB), on the ARPHA platform, where it will be co-published with Pensoft Publishers. Check out the announcement at biogeography.org/news/news/rela… #newbiogeo

Thrilled that our research is out and on the cover! The macro-eco-evolutionary interplay between dispersal, competition, and landscape structure using an upscaled individual-based model over 5 million years. 📄doi.org/10.1098/rstb.2… 🏝️ #gen3sis Renske Onstein Jonathan Chase

Another update in the Amarasekare saga. An insider from UCLA EEB (Peter Kareiva) speaks out. pamarasekare.org/an-insider-s

We studied how community assembly processes vary across ecosystems, latitude and taxon groups. We found that homogeneous selection dominates especially in marine systems while heterogeneous selection is rare Oikos Geosciences and Geography, University of Helsinki Caio Graco-Roza nsojournals.onlinelibrary.wiley.com/doi/full/10.11…

Hey #ESA2024 Ecological Society ! Anyone have any cool “synthesis” projects they’re looking for an awesome place to publish!?! Try Ecology Letters! Let me know if you have something or see something. Would be delighted to consider it. onlinelibrary.wiley.com/journal/146102…
