A new study published in Science Advances reveals that Madagascar’s striking landscape was shaped by not one, but two great rifting events, separated by nearly 80 million years.

Paper out in Ecology Letters!

We - incl. @westobymark.bsky.social @biogeokreft.bsky.social and others - show that traits are linked to species’ colonisation and extinction probabilities on #islands — with direct implications for species persistence and the Equilibrium Theory of Island #Biogeography
Resurveyed Island Vegetation Reveals That Species Colonisation and Extinction Probabilities Are Linked to Traits
We show that species richness and community trait composition on 132 Australian islands remained stable over six decades, despite high species turnover. Colonisation and extinction probabilities were....

The 2025 call for #MSCA Postdoctoral Fellowships drew 17,058 applications worldwide.

A 64.6% increase from 2024, it's the most popular call in over four decades.

Excellence thrives where it is enabled, protected and shared — and Europe provides that environment.

Ever wonder about what spatial scale of biodiversity #eDNA 🧬 samples capture?

We did. So we used data from the 16-ha Luquillo Forest Dynamics Plot 🇵🇷 to investigate the spatial scale of soil eDNA samples for tree🌴🌳 diversity.

We found that formerly common species have declined the fastest, on average.

Declines in North American birds are driven not by rare species vanishing but by sharp losses among formerly common species.

Too much sediment from rivers can hurt coral reefs, but in the long term, rivers can also keep reefs healthy by forming passes (gaps) that connect lagoons with the ocean. Megan Gillen explains how in her new paper (open access): doi.org/10.1029/2025...
