See our paper exploring scaling relationships of diversity-stability (and its components), applied to real-world data and metacommunity theory with habitat destruction. Was a phenomenal team to work with, led by @maowei_liang, @shaopeng_wang and Qi Yang, and I learned so much!

I’m thrilled to share our diversity-stability study on @ScienceMagazine Unifying spatial scaling laws of biodiversity and ecosystem stability | Science science.org/doi/10.1126/scie…

Unifying spatial scaling laws of biodiversity and ecosystem stability

While both species richness and ecosystem stability increase with area, how these scaling patterns are linked remains unclear. Our theoretical and empirical analyses of plant and fish communities...

Does fragmentation reduce biodiversity? New research provides insights into a 50-year old debate 🌎conservationcorridor.org/dig…

Resolving a 50-year debate: fragmentation decreases biodiversity on multiple scales - Conservation...

For 50 years, there has been ongoing debate over whether habitat fragmentation leads to biodiversity loss. The reason for this debate is that fragmentation is a complex process: fragmentation...

A recent study published in @NatureEcoEvo highlights the delicate relationship between habitat loss, fragmentation and biodiversity. @Jon_Chase03 and colleagues show that the total amount of habitat lost is a key factor influencing how fragmentation affects #biodiversity. #idiv

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.

🔍🌱 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/s41559-0… #biodiversity #idiv #research
Jonathan Chase@Jon_Chase0324 Jun 2024
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 @UniHalle nature.com/articles/s41559-0…
