Stronger El Niños reduce tropical forest arthropod diversity and function Nature - Time-series data from tropical forests tracking weather and declines in arthropod diversity and function show that fluctuations in species were largely dependent on their El Niño...

New article out today in Nature - intensified El Niño events under climate change appear to be chipping away at tropical forest arthropod diversity.

This is already leading to substantial losses in arthropod function in primary forests across the tropics.

Drivers of nocturnal and diurnal pollinating insect declines in urban landscapes | Proceedings of the Royal Society B: Biological Sciences Insect pollinators are essential for terrestrial ecosystems, delivering key ecosystem functions in the face of anthropogenic disturbance. Urbanization may be a key threat to pollinator communities. Ho...

🚨New research in Proc B! We show hoverflies & moths are more sensitive to urbanisation compared to bees, but tree canopies & semi-natural greenspaces help boost urban pollinator diversity. doi.org/10.1098/rspb...

A meta-analysis found that high-density managed honeybee populations can:

👉disrupt local biodiversity🌏
👉reduce pollinator richness🧪
👉alter plant-pollinator relationships🐝
...all with minimal benefits to crop yields!

Calls for evidence-based hive density guidelines 📑

More bad news for butterflies. Our new paper led by Wendy Leuenberger shows common species are declining even more rapidly than rare ones. @ZipkinLab

Delicious, but no playground

My 5yo has radicalized against AI because google maps falsely said a PDX Vietnamese restaurant had a playground and I believed it

low severity surface fire burning through a ponderosa pine forest

The Turkeyfeather Fire in the Gila Wilderness, NM has burned as a low-severity fire over about 24,000 acres (so far). This is a continuation of a fire regime that existed for millennia before the 20th century. This 🧵reviews the fire history of the Gila, as my colleagues and I have studied it. 1/18

Federal budget bill would boost logging — but cut funds to Oregon timber counties The proposed budget bill would increase logging on federal lands, but most of that money won't go to Oregon counties that typically receive a portion of timber sales.

As is, the "big beautiful bill" would increase logging on federal lands. But timber counties that have historically received a chunk of timber sales won't see any of that new money. www.opb.org/article/2025...

Journalists often ask for my thoughts on the contemporary US pronatalist movement. My assessment is based on my expertise and training as a social demographer, and my own research on childbearing behaviors at the individual and aggregate levels.

Strap in, b/c I've got a lot to say. 1/

Is there space for a tree median? Curious if they could block all left turns between stoplights and have cars do u-turns similar to PDX's cascade station. Cars doing lefts from the middle lane cannot assess oncoming 2 lanes + bike lane + 2-way pedestrian traffic

How Birth Year Influences Political Views (Published 2014) People’s political views are particularly shaped by events they experience between 14 and 24.

I like Andrew Gelman's model of cohort voting patterns based on events or president's approval during impressionable ages summarized here: www.nytimes.com/interactive/...

Fire is slightly better than Unreinforced Masonry

Oregon Department of Energy officially launches new heat pump program Funded last year by a $197 million federal climate grant, the Oregon Department of Energy program is available for owner-occupied homes, rental homes and homes under construction. Interested residents must work with approved contractors, who handle installation and submit rebate paperwork.

Oregonians can now apply for up to $2,000 in state rebates for heat pump installations through a new program launched June 17. When combined with federal incentives, some households could save up to $4,000.
