After 20+ years studying ecology, I've realised the it's about much more than plants and animals. It's really about understanding how complex systems work and change. 10 ecological ideas that changed how I see the world 🧵

Pour accélérer l'extension du réseau électrique, le Conseil des États s'attaque à la protection des marais, des milieux naturels fragiles. Contraire à la Constitution, ce projet de modification de loi est aussi préjudiciable aux forêts et aux cours d'eau. Le Conseil national doit corriger le tir!

Our paper “The global human impact on biodiversity” turns one today! 🎂 This figure did not make it into the paper, but I still think it is the most striking. It stacks the 3667 multivariate analyses. Each point is a community. 🔵=reference; 🔴=human-impacted. ⬇️
Synthetic stacked visualization of 3,667 multivariate community comparisons from a global biodiversity meta-analysis. Blue points represent reference sites and red points impacted sites. The two clouds overlap, but impacted communities show a clear directional shift away from reference communities.

Braided rivers look chaotic, but their food webs tell a different story. Using stable isotopes, we found that fish, birds, and spiders connect resources across huge spatial scales — revealing hidden structures that help stabilise these dynamic ecosystems. onlinelibrary.wiley.com/doi/abs/10.1...

Can semi-aquatic insects track the quality of terrestrial subsidy ? We found that predators responded the most, followed by shredders. Dispersal traits did not respond at all. In brief, predators and shredders are transmission belts of cross-ecosystem perturbations (see 🧵for more). 🧪💧🌎 rdcu.be/eg7RT
