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 🧪

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

NEW: per multiple sources, apparently there may be punishment/retaliation coming for EPA employees who signed the Declaration of Dissent this week. People are starting to get letters putting them on administrative leave, seems like potentially targeted at those who signed with their names.

New PFAS analytical method from our Great Lakes contaminants lab. We had issues reliably extracting PFAS from whole fish samples using Method 1633, so we found that lipid-extraction resulted in clean extracts. The work was led by my awesome, but Bluesky-less colleagues. doi.org/10.1021/acs....

In its simplest terms, the apparent demise of #USAID is the result of the world's richest man ending a program that helps millions of poor people. You don't need a Ph.D. in moral theology to see why this is an evil. You can just read Jesus's parables on the rich and the poor.
