Climate change is reshaping fish communities in the United States Rising temperatures and the introduction of non-native fishes have been linked to rapid changes in fish communities across the United States.

Changing water temperatures and human-driven introductions of fish have altered the composition of fish populations in streams and rivers across the USA over the past three decades, a study in Nature suggests. go.nature.com/47ZCcWH 🧪

Diverging fish biodiversity trends in cold and warm rivers and streams - Nature In the past three decades, fish abundance, richness and uniqueness have diverged across cold and warm streams, and the effects on native fish communities of stream warming and increases in introduced fishes have magnified each other.

Fish communities in US rivers have changed a lot since the 1990s, linked to climate change and species introductions - new research in @nature.com led by @rumschsl.bsky.social www.nature.com/articles/s41...

Really enjoyed your article! Thanks! Thought you made great points about limitations and future/alternative analyses.

Sometimes you set out to ask one question and you end up addressing something different. Here is an example of that where we set out to synthesize US biomonitoring data and pesticide data and ended up asking a biodiversity question. Fun working with this team!

Our research group just published a study in Nature on how fish biodiversity in U.S. rivers and streams has been changing over the past 27 years (1993–2019). The results show sharply diverging trends depending on historic and changing water temperature. 🧵 rdcu.be/eH0l8

Exciting collaboration with colleagues from the US and Frederik de Laender - lead by S. Rumschlag and Mike Mahon - on how climate change has lead to alterations in US fish diversity over the last decades. Paper just out: www.nature.com/articles/s41...
