Extreme events and river biodiversity under climate change - Nature Reviews Biodiversity Extreme events — such as floods, droughts and heatwaves — are escalating in frequency, magnitude and duration. This Review discusses the implications of these global changes for biodiversity in rivers...

Rivers aren’t just warming: they’re being reshaped by extreme events
Our new paper in @natrevbiodiv.nature.com shows how floods, droughts & heatwaves are pushing ecosystems past their limits, with recovery no longer guaranteed
We can build resilience, but it requires a shift in how we manage rivers

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.

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/... 🌐🐠🐡🦈🐟

Phenology‐informed decline risk of estuarine fishes and their prey suggests potential for future trophic mismatches Conservation scientists have long used population viability analysis (PVA) on species count data to quantify critical decline risk, thereby informing conservation actions. These assessments typically...

So excited to share our new paper out today in Ecological Applications @esajournals.bsky.social!

We used time-series modeling explore ecological risk for fishes and their prey in the San Francisco Estuary during key phenological windows that shape food web dynamics.
