Happy Nevada day to all who celebrate. I see some people who have dressed up in spooky costumes. I don't totally understand what this has to do with Nevada, but to each their own.

The megadrought currently sucking the Southwest dry is having far-reaching impacts on wildlife, especially migratory birds. The elegant trogon is one of them. With arid conditions intensifying, the birds are producing few young, leading to population declines that worry researchers. 🌎
A Megadrought Is Reshaping Birdlife in the Southwest

Cool piece, highlighting some of the impacts of the recent wildfires on the North Rim of the Grand Canyon, as well as impacts of shutdown in slowing recovery.
I'm riding my mountain bike on the 850-mile Arizona Trail this fall to see and write about #climate impacts along the way. We're publishing weekly dispatches from the trail in The Arizona Republic | @azcentral.com as I go.

Join the Laughlin lab and our new NSF funded project! Awesome opportunity to visit forests across the western US and examine the functional basis of demographic responses to drought and wildfire.
Great PhD opportunity with an excellent supervisor:
Quantify traits of tree species across the western US to determine how tree populations and forest communities will respond to drought and fire.

Density‐dependent growth and dispersal can accurately forecast near‐term range shifts in a dominant dryland tree species

Three of nine regional Climate Adaptation Science Centers (CASCs) across the country will shut down by October if OMB continues to withhold funds to renew their 5-year cooperative agreements - which includes funds already appropriated to the CASCs by Congress for Fiscal Year 2025.
“This is just another way to stop science,” said Bethany Bradley, the center’s co-director. The Northeast Climate Adaptation Science Center is 1 of 9 regional hubs across the country that helps state and local partners develop plans to adapt wildlife, water and land to the effects of climate change.
