The ecological impacts of drought on California's Sierra Nevada are far more complex and context-dependent than previously understood, according to a recent study by Kyle Leathers and ESPM professor @albertruhi.bsky.social.

Rivers shape lives, stories, and futures. Dive into this intergenerational conversation with Zak Podmore, Rose McMackin, and Becca Lawton as they explore the power of Western rivers, their creative journeys, and the resilience of water. #coloradoriver #cawater www.terrain.org/2025/intervi...

Pleased to announce that we are looking for a post-doc to join @wesnerlab.bsky.social to study the relationship between body size, temperature and nutrients in stream ecosystems. Position details can be found here: yourfuture.sdbor.edu/postings/45969 Happy to answer any questions!

Our paper on drought & riparian phenology is out in @globalchangebio.bsky.social, skillfully led by PhD candidate Rose Mohammadi! Upshot: #Drought pushes down water tables & shortens tree growing seasons by intermittent streams - and that response is visible from space #timeseries

How vulnerable are riparian trees to drought? Using groundwater and satellite data from a California waterhsed, our new paper found that trees by drying rivers lost up to 5 weeks of growing season, suggesting they’re nearing critical groundwater limits. onlinelibrary.wiley.com/doi/10.1111/...

New paper out led by @josemaferca.bsky.social ! Using stable isotope enrichment, we tracked aerial dispersal in a temporary river. As drying intensifies, conserving pools as refuges will be essential to prevent biodiversity loss. Access OA paper here: doi.org/10.1111/fwb.... @biologiaub.bsky.social

Wow, this is amazing. Listen live to whale songs!🐋🔊

Does tidal marsh #restoration "work", if the goal is bringing back key species AND the trophic interactions that support them? A thousand stable isotope samples later, we have answers! 💯 work by PhD student Megan Pagliaro: esajournals.onlinelibrary.wiley.com/doi/10.1002/... #SanFrancisco #BayDelta

Curious about how droughts alter mountain stream biodiversity - and why space-for-time substitution is not always a good idea when studying climate change impacts in rivers? Read our latest lab paper, led by Kyle Leathers in Ecological Monographs! @esajournals.bsky.social dx.doi.org/10.1002/ecm....

Nice article by @jimrobbins.bsky.social in @nytimes.com on one of my favorites - marbled murrelet - and its potential fate given changes to our forests, oceans and the US Endangered Species Act. @coforegonstate.bsky.social 🧪

Do heat waves happen in rivers? How do river heat waves (RHW) compare to air heat waves (AHW)? www.pnas.org/doi/10.1073/... Here we show: 1) RHWs occur less frequently & intensively but last twice as long as AHWs; 2) RHW have risen much faster than AHWs. Congrats to Dr. Kayal Sadayappan!

How does trophic connectivity between different ecosystems work at a landscape scale? We applied a novel conceptual framework with functional traits and fatty acid biomarkers to assess direct and indirect effects of landscape drivers on cross-ecosystem connectivity in stream-riparian #foodwebs

Rapid evolution occurs, but speciation rates are nowhere near fast enough to replace the loss of entire endemic lineages. Bioinvasions & other stressors are causing global biodiversity losses that could take millions of years to fill - or are irreversible. onlinelibrary.wiley.com/doi/10.1111/...

Here is an alternate take on my OpEd defending Science. As i mentioned last time there is a hunger from the public to hear from science experts. I encourage more of us to write to papers where you have roots on matters defending science, facts and democracy www.ptreyeslight.com/opinion/we-m...

Such an inspiring story, and so symbolic - teens, all descendants of the region’s Indigenous tribes, paddling along a river that has been recently freed by the largest dam removal project in American history!

Petrostates and well-funded lobbyists at UN-hosted talks are derailing a deal to cut plastic production and protect people and the planet #plasticstreaty #plastics www.theguardian.com/environment/...

The Global Plastics Treaty starts today - it’s our best chance to cut plastic production and start to clean up this plastic mess. But it’s under threat from nasty plastic polluters who want to keep drowning us in plastic. Sign the petition to kick them out of the plastics talks now: act.gp/4oDU0wD

New paper by @chaevangelista.bsky.social ‬ and colleagues shows how California mountain river communities can be altered by climate change, through longer low flow periods, and the interaction of a predator, here the infamous brown trout. doi.org/10.1002/lno....

Last year, the final of four hydroelectric dams on the Klamath River were removed in the largest project of its kind in US history. The river that straddles the California-Oregon border has since been reborn.

My sign is ready #NoKingsDay

How bad will it be? Catastrophic. Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come. But, this is the WH's *proposed* budget. Speak up now before it is too late. (inflation adjusted $-s below)

If you think the seasons are feeling… different, you may be right. Our new review in Science (@science.org) shows that Earth’s changing rhythms could have major and underestimated consequences for life on Earth. 🌍🧵 www.science.org/doi/10.1126/...

So interesting - loved the stories on asynchrony & influence of environmental noise color on metapopulation dynamics!

America cannot long remain free, nor first among nations, if it becomes the kind of place where universities are dismantled because they don't align politically with the current head of the government.
