Food web complexity underlies biodiversity effects on ecosystem functioning Work expertly led by @barnesecodiv.bsky.social and @bgauzens.bsky.social
Andrew Barnes @barnesecodiv.bsky.social · last mo.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

Saw this work presented at the Cefas student conference. I love it - great example of how to make the absolute best out of what initially looks like a fieldwork disaster (study organism gets eaten…)

The COINS conference is kicking off with very strong and inspiring talks by @marienordstrom.bsky.social about ecology and food webs and @kellykrause.bsky.social about scientific visualizations
Thoroughly enjoying the COINS 2025 in Vilnius. Today’s speakers include Dr Eugene Koonin and Creative Director Kelly Krause (Nature) as well as yours truly. Thank you and congratulations to the organizers and Domas Sakalauskas in particular!
🌊 Ocean Census scientists have identified 800+ new marine species using AI imaging & DNA analysis. From deep-sea crustaceans to jellyfish, the findings highlight how little we know about #ocean biodiversity. What else might the deep sea be hiding? 🌏🧪 oceancensus.org/publications... #Biodiversity

"We need a fundamental shift in how we produce food—one that recognizes that food production efficiency comes at the cost of ecosystem robustness and the loss of #biodiversity. By mimicking nature's complex mosaic of habitats, we can strengthen the resilience of food webs." 🌐🧪🌎
Global food production has resulted in significant biodiversity loss, research shows
As the world grapples with the challenges of climate change and food insecurity, the need for sustainable food production has taken on a new urgency.
