Postdoc extraordinaire Lise Comte (now faculty at Illinois State University) just got this really nice paper published in Global Ecology and Biogeography, entitled “Human stabilization of river flows is linked with fish invasions across the USA”. In this paper we quantified widespread changes in river flow regimes US-wide, and found that such alteration has favored invasions by filtering specific life-history strategies. Notably, high levels of flow stabilization and propagule pressure interacted: where co-occurring, these two drivers were associated with higher fish invadedness levels than expected based on either of their individual effects alone.
