Right now, Oregonians should listen very hard to @opbkmhdcreators.bsky.social union. The voices you hear on the radio at OPB are generally poorly-compensated, some working two jobs, and the wage gap between the CEO and the actual journalists is a gap of hundreds of thousands of dollars.

New study on arthropod declines @natecoevo.nature.com 🪲
In two time series @jena-experiment.bsky.social & @bexplo.bsky.social we show how community (dis)assembly underpins local biomass declines.
It mostly boils down to species loss, with identity losing relevance.

🚨We analyzed 138 million geocoded property tax records to quantify how municipal boundaries spatially overlap onto economic segregation in every US metro area—creating disparities in localities’ ability to fund public goods. And we made an interactive map of our results! [1/16]

Even your older nature photos can help scientists today! As long as you know when and where you took the photos, you can post your nature sightings on iNaturalist anytime — and they'll still contribute to science and conservation. Got anything in your camera roll to share? 👀

NOTE: No detectable change in *activity density*: they measure bugs that have dispersed into the upper atmosphere. That is quite a few steps from abundance.
Consider (just one) scenario: abundance declines but warmer temps promote flight activity.

In October 2023, there was a mass die-off of kokanee during the first drawdown of Green Peter Reservoir. Floating dead fish everywhere. It was ugly. Turns out, many fish survived and at least 500 reached the ocean and have returned transformed into sockeye salmon. Nature! tinyurl.com/4r8pr5n2

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.
