Here's a new genome from the CCGP: The Lahontan Cutthroat trout (Oncorhynchus clarkii henshawi). This species, endemic to Western North America, may be in danger of extinction.

Inside me there are two wolves. One of them has a 15 genome edits the other 20 genome edits. Neither of them is a dire wolf.

Colossal Bioscience did not revive dire wolves, despite a sensationalist Time Magazine cover story.

Making genetically modified animals that are cosplaying as extinct species is not de-extinction.
Dire wolves were not close relatives of gray wolves. They last shared a common ancestor more than 5 million years ago. What Colossal has done is make something new and slapped a dire wolf sticker on it, as if an organism equals a hypothetical genome.
Dire Wolves Were Not Really Wolves, New Genetic Clues Reveal
The extinct giant canids were a remarkable example of convergent evolution

One of my first internships was with ME Sea Grant (where I learned R!), and I wouldn't be where I am now without that opportunity. This is devastating for the future of coastal/ marine management in Maine.
Maine Sea Grant changed my life when they gave me the Knauss Fellowship on Capitol Hill. I owe them my career. How will young scientist looking to use our skills to serve the public find opportunities going forward? We are killing ourselves. www.pressherald.com/2025/03/01/m...
Maine Sea Grant funding terminated as Trump administration makes cuts to NOAA
The move to discontinue the $4.5 million grant program leaves 20 employees and the Sea Grant’s programming in limbo.

Someone should write a book about the genomics of marine organisms titled The Shellfish Gene

Remember: you didn't use RStudio for your analysis. You used R for your analysis.

Happy New Year!
P.S. Here’s us last night below.
Merry #fishmas! Along with being adorable, Lumpsuckers are used in Atlantic Salmon #aquaculture to eat sea lice, resulting in interesting genetic differences between wild and domestic populations. #25daysOfFishmas
Been waiting for the #Fishmas Lake Sturgeon day! 🐟 #25DaysOfFishmas

Visited Chicago just in time for #Garweek and #fishmas! Saw live Shortnose & Longnose gar at Shedd Aquarium, then fossils at the Field Museum. The living gar's DNA is very similar to their ancient relatives!

A study of 632 freshwater fish species from 9,989 locations finds climate warming affects fish abundances, with increases at the poleward edges of species’ distributions and declines at the equatorward edges of species’ distributions. In PNAS: www.pnas.org/doi/10.1073/...
Quick field trip attempting to retrieve temperature loggers failed due to high water levels, but views like this remind me of why I'm doing #ecology
Great image illustrating why aquatic connectivity matters *laterally* as well as up/downriver: These Central Valley juvenile chinook are the same age, but the bottom "floodplain fatty" reared in hyper-productive off-channel wetlands.

as both a scientist and an occasional scientific illustrator i'm pretty grossed out by a journal using AI imagery. not only are AI image generators fundamentally based in plagiarism (y'know, the thing we're really not supposed to do?), they're a major source of emissions + environmental degradation

Took some time to come together, but so happy to have this paper out!
Hey! I'm a grad student studying salmon genomics, I'd love to be added!
