PFAS levels in #GreatLakes fish are dropping, study finds The declining levels were driven by an industry phase-out of legacy PFAS chemicals www.wpr.org/news/pfas-le...

How #climatechange is reshaping fish communities in the United States as temperatures rise and non-native fishes proliferate: @ian-vaughan.bsky.social overviews recent extensive work by @rumschsl.bsky.social www.nature.com/articles/d41... www.nature.com/articles/s41...

Climate change is reshaping the fish communities of rivers across the US - my commentary in @nature.com to accompany the new study led by @rumschsl.bsky.social rdcu.be/eHY6B 🌍🧪

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 🧪

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...

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...
