Today at @unbreaking.org we have a big update to our page on transgender healthcare. A TIMELINE!!! And the explainer has been rewritten to be clearer and easier to follow (if not any less soul crushing).

If you need a primer on all the ways this administration is attacking gender affirming care:

Transgender Healthcare: Explainer — Unbreaking

How the administration is breaking the government, and what that means for all of us.

Today’s incoming atmospheric river could bring one of the bigger flooding events of the past decade in Oregon, NWS meteorologists said, with around 16-18 streams currently forecast to see some level of flooding. Wind and wet soils could also bring widespread outages: tinyurl.com/34fptzsy

The class-action lawsuit is the first of its kind to target Big Oil over rising home insurance costs.

I started getting reports of an unseasonal Joshua tree bloom in the last few weeks, and looking over records on @inaturalist.bsky.social it's pretty widespread! So we're putting out the call for folks to record this "bonus bloom" and help us study it 🌿

Weird wet weather has Joshua trees flowering early — or late? Help the Yoder Lab map this “bonus bloom” to understand why

Mississippi seems to have a long-term increasing trend in test scores, which is great! Probably not due to a silver bullet switch in reading that happened partway through the long-term trend.

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.

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? 👀

White text reads "As long as you know the dates and locations where you took them, you can post your older photos of wild nature to iNaturalist! Older records of nature can (and do) contribute to ongoing science and conservation efforts — just like new ones do. What's in your camera roll?"

Noting that I'm talking about land-use change in the USA, here deforestation == sprawl for development which peaked in the 90s. While pesticide use changed drastically in the 90-00s with glyphosate and neonicotenoids

My view echoes points made by van Klink & Crossley, but I wanted to point out that (similar to Monarch butterflies) the timeframe of a population trend needs to match the environmental changes influencing it. Paper has interesting results wrt temperature trends in Northern sites linked to declines.
