Fun fact that St. Louis metro has 10.1 governments per 100,000 residents (Table 1)

🚨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? 👀

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

Tyson Wepprich @tysonwepprich.bsky.social · 8d

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.

screenshot of text: Ten years might also be too short a time to see trends in insect numbers, adds Tyson Wepprich, an ecologist at the Oregon Department of Forestry not involved in the research. That’s particularly true because two of the biggest proposed culprits in insect declines—deforestation and agricultural pesticide use—were on the rise well before 2012, he says. Digging further back in time, potentially by repurposing older weather radar data, will be key to studying long-term, large-scale trends, Wepprich says. “Then you could start getting into those questions.”

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.

New paper by Tielens, Stepanian, & Kelly uses weather radar to monitor flying insect communities across the USA over 10 years. Detected no change in density over 2012-2021, with lots of station to station variation. #openaccess paper here: onlinelibrary.wiley.com/doi/10.1111/...

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.

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! 🐟🧪🌎

www.opb.org/article/2025...

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.
