Our new study @Nature synthesizes time series on insects from sites across the world. Building on our previous work @idiv, we show that abundant species are declining faster than rarer species (richness is also declining). Expertly led by @PunksInScience

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!

Our paper led by Thiago Gonçalves-Souza is out. Habitat fragmentation and habitat loss reduce biodiversity. @Nate_J_Sanders @Jon_Chase03

Results from 37 studies distributed worldwide, on plants and animals, comparing continuous and fragmented landscapes.

Hey #ESA2024 @ESA_org ! 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.

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_Journal @GeoHelsinkiUni @GracoRoza

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. 📄https://t.co/sX7gv9hxI0 🏝️ #gen3sis @RenskeOnstein @Jon_Chase03

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

[@comecology.bsky.social @com_ecology]

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! Looking forward to enlightening collaborations!

Leaving #Leipzig after my #FastAndFurious visit to @idiv visiting @Jon_Chase03 lab's to start the next #MetaHeroes adventure!

Inspiring and insightful exchanges to begin drafting & exploring long-term landscape degradation effects on diversity! @Zsofia_Horvath1 @MSCActions

[iDiv Biodiversity Research @idiv]

🔍🌱 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. https://t.co/KeaxcgWKM5 #biodiversity #idiv #research

[Jonathan Chase @Jon_Chase03]

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

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. https://t.co/MMeyqx2pgh

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: https://t.co/4o1Ga04tw2
