Check out our new insect decline paper. By analysing 36 yrs of German ground beetle distribution data, we show:
- ~80% of species have declined, with significant declines for >50%.
- The decline was similar across species traits and threatened status.

Few people outside North Carolina have heard of Paul Newby, the chief justice of the state’s Supreme Court.

But Newby has had a huge impact on America and his state. He’s done this with the goal of delivering what he’s called “biblical justice, equal justice, for all.”

My heart was jubilant while reading this story this morning - more than 100 Chinook salmon have passed the former Klamath River dam sites as well as the fish ladder at Klamath Lake and are naturally spawning in Oregon headwaters for the first time in over a century! 🐟🧪🌎

Salmon clear last Klamath dams, reaching Williamson and Sprague rivers
Just a year after four dams were removed, a group of fall Chinook have migrated nearly 300 miles into the Upper Klamath Basin.

Oof, same battery issue as last year's recall for 2019-2020 cars which still has no fix. Lithium deposits can form in the battery (estimated to affect 1% of cars in recall) & cause a fire when fast-charging.

Hearing scheduled for 7 on keeping CA National Guard out of Oregon has finally started. Judge says they had some technical difficulties.
Drought and insects have killed an unprecedented number of Oregon’s Douglas fir trees during the last decade, costing billions in timber value, damaging infrastructure and ramping up wildfire danger.

Sometime around the turn of the 20th century, the sea mink disappeared from Maine's coastal waters. Its loss came during a rush of North American extinctions, but many today have never even heard of it.

My latest for Smithsonian:

It might be among the first mammals to go extinct in North America after colonization. But can scientists prove it was even a distinct species?

I recently spoke at a neighborhood association meeting about native plants in the city.

Going to meetings like this can reach audiences that aren't following scientists on social or reading up on their own.

If you wanna take any bits/pieces of what I said to them, handouts & slides in the thread.
I'm developing a grad course on experimental design (study design generally) & data analysis in biology. What topics, papers, etc. do you think are most important? If you teach something similar, I would love to hear what/how you teach (if you are willing to share a syllabus that would amazing!).

Our latest research on fire impacts on snow melt timing across the Western US was just published in @aaas.org Science Advances. Read here: www.science.org/doi/10.1126/...
Impact of current and warmer climate conditions on snow cover loss in burned forests
Wildfires are causing earlier snowmelt across the western US, and this effect would be exacerbated with projected warmer winters.

Immigration advocates say if you see ICE targeting someone, knowing what to do in the moment is critical to protecting immigrants. It’s hard to know what to look for, but this guide can help you better understand how to be an effective bystander in Oregon, and your legal right to do so.
What to do if you spot ICE in your community
Amid President Trump’s immigration crackdown, local community networks are the first line of defense. Here’s what Oregon advocates say you should do if you see agents detaining someone.
