State water officials are asking towns and industry along the North Platte River to assess their water rights and whether they might have to tap into an emergency water bank.
For now, those with "junior" rights must shut off their spigots, with little snow and water relief in the forecast.
Yes. And I love the muppets gif
Winter is getting real here!
Want to study the genomics of repeated adaptation with data from hundreds of species? New funding for non-Canadians @ grad or postdoc level. Internal competition at UCalgary with very short deadline so please get in touch ASAP!!

It certainly looks like 2026 will require a lot more running and fiction…

I coped with 2025 by reading and running. I read 52 books, mostly fiction. 34 new to me, 18 comfort rereads. I also ran 1,200 miles, including 2 50km races and a 43 mile fun run along Lake Superior at Pictured Rocks.
Map and phylogeny of complex hybrid zone between two darter species
Comparison of Fst estimates from ddRAD vs lcWGS
Huge congrats to my mentee @pfschwarz.bsky.social on her first first-author paper! Three-way secondary contact and mosaic hybridization in darters. Plus a bonus comparison of ddRAD vs lcWGS. @fishgenomes.bsky.social @tjnear.bsky.social #fish #evolution #genomics

The #25DaysofFishmas calendar with Dolly Varden trout on December 21
If a “little toy doll(y) that toddles and coos” is on your list, Salmonid Claus is definitely going to deliver on Day 21 of #25DaysofFishmas!
We end the northwest leg of our road trip with the Dolly Varden (Salvelinus malma), a brightly colored fish + this week’s #SundayFishSketch mystery species!
✍️New blog post! Evolution Has No Plan: Why Organisms Don’t Rewrite Their DNA
jenteottenburghs.wordpress.com/2025/12/18/e...
The news articles on polar bears that are “rewriting their DNA in response to climate change” triggered me to write this blog post. Evolution has no foresight.
The #25DaysofFishmas calendar with Bonneville Cisco on December 16
🎶I’m dreaming of a white(fish)-mas🎶
No need to just dream it! On Day 16 of #25DaysofFishmas, our road trip heads to the high country for the Bonneville Cisco (Prosopium gemmifer), a species of freshwater whitefish found only in Bear Lake on the border of southeast Idaho and northern Utah.
The #25DaysofFishmas calendar with Largescale Sucker on December 17
Are you a sucker for cheesy holiday movies? Well, you’re in good company!
Day 17 of #25DaysofFishmas brings us the Largescale Sucker (Catostomus macrocheilus), a fish whose distinctive feeding habits and even scientific name - which means “large lips” - makes it perfect for mistletoe lovers 😘
Can professors enroll? Asking for a friend. Yes, that friend is me!

A beautiful shiner wearing a Santa hat; the text says December 13
The beautiful shiner is a small fish (<3.5 in/9 cm) that's part of the Leuciscidae family (shiners, daces, minnows) and the Cyprinella genus - also known as sailfin shiners. Like many other Cyprinella species, male beautiful shiners are known for their vibrant breeding colors #25DaysofFishmas
And also the ref. genome we used for analyses of all 3 species was C. latipinnis, since that's the only one we had assembled.
We've found some signal for bluehead sucker (Catostomus discobolus), but didn't get a clear indication for the two other species in our analysis, except that we think that sex associated genomic regions might differ across this group of hybridizing sucker species. doi.org/10.1093/jher...
I'm recruiting a Ph.D. student for Fall 2026.
Interested in comparative studies and trait evolution in fishes?
Send me an email with a CV and research interests. Please take a look at my website (jcorush.github.io ) for more information about my research.

A Mountain Mullet wearing a Santa hat; the text says Decemebr 6
Mountain mullet is part of the Mugilidae family (grey mullets), a group whose members are mostly found in marine coastal waters worldwide. The mountain mullet goes against the flow (literally!) of its family by migrating far inland and spending most of its adult life in freshwater #25DaysofFishmas
Madtoms are kind of the Tiny Tim of the catfish family.

A Suwannee bass wearing a Santa hat; the text says December 4
Suwannee bass is one of the smaller members of the black bass genus (Micropterus) typically growing only ~8 in/21 cm long - though females grow faster + reach larger sizes than males. Mature fish often have turquoise blue coloration on the cheeks/belly that's brighter when breeding #25DaysofFishmas
This is the time of year when I find cryptic post it notes in my own handwriting that say things like “send email”, with no additional details
A Florida gar wearing a Santa hat; the text says December 3
Like the 7 other living species of gars, Florida gar have unmistakable long slender bodies, beak-like jaws, and interlocking diamond-shaped scales. They’re one of the smaller gars, often ~2 ft (0.6 m) long - compare that to the alligator gar which can grow to nearly 10 ft (3 m)! #25DaysofFishmas
The #25DaysofFishmas calendar with redear sunfish on Day 2
Rudolph, the red-eared reindeer! 🦌
With ears so bright, the Redear Sunfish (Lepomis microlophus) guides us into Day 2 of #25DaysofFishmas! This member of the sunfish family found throughout the southeastern US is a warm-water loving ray of sun on a cold winter day ☀️
A Christmas darter wearing a Santa hat for Day 1 of #25DaysofFishmas
The Christmas darter is one of ~200 species of darters (fish in a group called Etheostomatinae) that are all native to North America + mostly found east of the Rocky Mountains. Christmas darters are Tiny Tims, typically only growing <2 in (5 cm) long #25DaysofFishmas
The #25DaysofFishmas calendar with the Christmas darter on Day 1
🎶It’s beginning to look a lot like #Fishmas🎶
There’s no better fish to kick off this year’s #25DaysofFishmas than the aptly-named Christmas darter (Etheostoma hopkinsi)! We get our road trip started down in the southeastern US with this small species of fish who has big holiday spirit all year long
To apply, please send a letter of interest, CV, transcript (unofficial is fine), and contact information for three references to Dr. Liz Mandeville, lmandevi@nmu.edu. Review of applications will begin immediately. Please apply by December 15, 2025 for full consideration.
NMU is located in Marquette, Michigan, in the Upper Peninsula of Michigan. Marquette is a small but vibrant city on the southern shore of Lake Superior, located close to beautiful natural areas. It’s a great place to live and work, and the proximity to many of our field sites is an advantage.
