Important study -> More complex ecosystems, especially those with higher #diversity of #predators, function more effectively! Led by @barnesecodiv.bsky.social. Exciting to see this published in @nature.com. @qmulsbbs.bsky.social

Published today in @nature.com, our study shows that the #foodweb trophic structure is critical for #ecosystemfunctioning. Read it here: rdcu.be/frxEl This has been an incredibly rewarding collaboration with many amazing scientists! 🌐🧪🦑🍁🌱 @waikatouniversity.bsky.social @idiv-research.bsky.social

New paper out examining fish food web degradation in the Anthropocene. We show the structure of aquatic food webs are changing-- even when species richness doesn’t. These signals are strongly associated with decreases in body size within fish communities. www.science.org/doi/10.1126/... 🌐🐠🐡🦈🐟

Degradation of fish food webs in the Anthropocene

The decrease in body size driven by the selective species turnover is widely altering fish food web topology and function.

The food chains on modern Caribbean coral reefs may have shortened by up to 70% compared with those on their prehistoric counterparts, according to research in Nature. The findings suggest that modern reefs could be increasingly vulnerable to external stressors and ecosystem collapse. 🌍 🧪

Fossil isotope evidence for trophic simplification on modern Caribbean reefs - Nature

Using nitrogen isotopes from ancient and modern fish otoliths and corals, the study shows Caribbean reef food webs are now 60–70% shorter and functionally less diverse, indicating human-driven trophic simplification and increased risk of collapse.
