Nine ways extreme events reshape river biodiversity How floods, droughts, heatwaves, and compound events are impacting life in rivers

What do floods, droughts, heatwaves and compound events actually do to river ecosystems?

My latest post walks through nine real-world impact pathways โ€” from reaching physiological limits to cascading networkโ€‘wide effects.

A guided tour of a rapidly changing reality.

I'm immensely grateful for Hypothesis Fund support!

For years, we've speculated about "rules" for mixotroph metabolic flexibility. This funding will allow us to integrate new mol & cell bio tools with our modeling optimization approaches.

Thank you ๐Ÿ™ to scout Ginger Armbrust for finding us!

Incorporating realistic ecological interactions changes our understanding of which traits are optimal in different environments, including the temperature-size rule.
