New article alert!
Is there always longitudinal connectivity in rivers? What about those fragmented by lakes and semi-alluvial reaches? We found extremely low connectivity in paraglacial regions based on continuity of channel width changes and in riparian vegetation.

Disrupted geomorphic and biotic stream connectivity in paraglacial regions - Communications Earth & Environment

Natural disconnectivity in paraglacial river networks disrupts downstream trends in channel width and riparian plant richness, as revealed by two catchments with local controls on channel width and species dispersal.

Unprecedented cuts to the National Science Foundation endanger research that improves economic growth, national security and your life

The Trump administration has terminated hundreds of federal grants that support engineering, biology, geology, computer science, STEM education and much more.

I received a heartbreaking email today: A paper in a special issue I’m editing is being retracted because one of its authors is afraid of losing their job and their legal status in the U.S. if they publish a scientific study on evolution. Yes, on evolution, nature's engine of diversity.

Hydrology Paper of the Day @fluvialsweden.bsky.social on video-based surface velocimetry analyses to quantify ice-on-river processes for rivers situated in Finland and Sweden: ice cover and flow velocities; effects of air temperature and ice melting; and linkages with environmental parameters.

New study on river ice! Phd student Tuure Takala led this study where we used video-based surface velocimetry analyses (STIV) to examine flow velocities during freeze-up & break-up… interesting effects of partial river ice!

A wildfire swept through Wyoming’s Medicine Bow Forest in 2020, yet one green oasis remained: a beaver-engineered wetland. 🔥

Scientist @emilyfairfax.bsky.social is proving what nature has long known: beavers are the solution.

Dear Democratic Party: why are you not screaming this from every rooftop? Why are you not holding press conferences with these poor fired people - putting a face on what the richest man is destroying?

“The thing that I can’t get over is that the actual richest man in the world directed my fucking firing. I make $50k a year and work to keep drinking water safe. The richest man in the world decided that was an expense too great for the American taxpayer.”

Yesterday many thousands of federal employees were terminated. This is a Reddit thread for federal employees that got laid off.

The U.S. Department of Labor is organizing a protest. Elon Musk’s staff will be present at the Frances Perkins Building in Washington, D.C., today at 4 p.m. It was mentioned that staff should plan to stay late after the 4 p.m. meeting to assist with setting up Elon Musk staffers into their systems.

🚨 all EGU journals have cancelled their Twitter/X feeds 👏👏 But for reasons beyond me have decided not to engage with BlueSky 🤷 - if you’d like a BlueSky presence for your favourite EGU journal - I’d suggest getting in touch with @eurogeosciences.bsky.social (or liking this message?) pls RT 😀👏

Sharing this from Rt. Rev. Jonathan H. Folts, Bishop of the Episcopal Diocese of South Dakota.

“One of our own priests was targeted at his home—so let no one say, ‘it can’t happen here.’ It can. It has. It is. And rest assured, we will not remain silent or passive in responding.”

My heart aches.

Keep pushing back. Hard.

He blinked on tariffs.
His California water stunt failed and has been ridiculed.
He was forced to roll back cutting grants and govt payments.
NSF support is resuming.
CDC webpages are being restored.
Street protests are starting.
Lawsuits are being filed.
Fight back.

Hear me out —

If parents call colleges freaked about their FAFSA data being leaked, schools may have to issue statements — which would reach a whole lot more families about how warped this is.

Organizing isn’t always calling electeds. Sometimes it’s just calling people with a bigger megaphone.

Musk staff have access to student aid data now.

At least some DOGE staffers have gained access to multiple sensitive internal systems, the people said, including a financial aid dataset that contains the personal information for millions of students enrolled in the federal student aid program.
