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...

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.

Biological community dynamics alter the timing, amount, & composition of insect biomass and metal export. In urban, impacted streams, altered composition and phenology of emergent insect communities can increase metal flux, posing elevated risk to consumers in paired terrestrial ecosystems!

Excited to share our new article w/ @drbiogc.bsky.social published in @freshwaterscience.bsky.social on the gravity defying act aquatic insects 🦟 undertake moving themselves and heavy metals from urban stream ecosystems into the waiting mouths of terrestrial predators 🐸🕷️!

Abstract Watershed urbanization leads to a characteristic set of physical, biological, and chemical stressors that reduce the biological diversity of aquatic insect communities. We examined how aquati...

I’m devastated to hear from EPA researchers that they expect to loose their jobs in the coming weeks as EPA ORD is closed. PLEASE spend a minute today to call your elected officials to share why this research is so important (article below overviews the importance of EPA’s research arm)

Jonny Behrens @jonnybehrens.bsky.social · Apr 10

Research funded by EPA ORD gives water managers across the nation the data + knowledge they need to provide safe drinking water to every resident, regardless of zip code.

Thanks @newrepublic.com for spending time to talk and for this well written article! newrepublic.com/article/1936...

Research at EPA ORD inspired me to pursue a career to study/protect our drinking water resources so that every city, regardless of if they vote blue or red, has access to safe drinking water. EPA ORD is one of few agencies that fund research to ensure air is safe to breath + water safe to drink. 💔

This is terrible news & just one part of a bigger picture.

Prepare yourself for ongoing updates about the “reduction in force” this month and more again in April.

Talk to your community about it. They may not believe it at first - it sounds unbelievable! But we must bear witness & explain.

It was a blast to join you in the field! It’s incredible how all that algae (& little caddisflies + chironomids munching within) made it through the storm - what resilient ecosystems!

The USGS plays a critical role in monitoring rivers nationally. As scientists we rely on the data to understand, for example, how streams that had historic flooding during Hurricane Helene are recovering (& the people who rely on them). Ask your reps to keep them open! ww2.aip.org/fyi/usgs-fac...

The NSF postdoc fellowship is one of the most scientifically competitive programs that funds the next generation of scientists…the new administration’s policies left them without pay @statnews.com

National Science Foundation suspends salary payments, leaving researchers unable to pay their bills

An NSF online payment system remained down after the federal funding freeze was lifted, leaving early-career scientists scrambling to pay bills
