New #RemoteOffice for the next couple weeks on the NOAA vessel Oregon II ! Joining their annual summer groundfish survey on the Gulf with my graduate student Adam Boyd and Auburn's fish collection manager David Werneke. 🧪🌎🐟🐡🐠🎣🦈

Really enjoying the members of our #fish lab at #UAB! Diverse projects on local species but also of course on #Antarctic fishes! 🐟🇦🇶🌎🧪 Great to have them all come over for a BBQ in between rain showers! 😅

I like that the #chanterelle season in #Alabama is late spring (and not rainy gloomy fall like in Oregon)! Got a nice haul of almost 10 pounds that we turned into a deliciously lavish dinner, several precooked meals portions, gifts to friends, and a bunch of pickled mushroom jars! 🍄🥒🤤

ZebrafishRock @zebrafishrock.bsky.social over ten years and going strong 🧪🐟

Had fun #volunteering at the Community Food Bank of Central Alabama this morning! We got 774 boxes ready! Each box feeds a family of 4 for a week, so that's 3096 people, incl. many kids, that will have needed meals this week. Thanks Food Banks workers, you're real good people! #FoodBank #Alabama

My new coworker is definitively the cutest, but when she's not sleeping she has a hard time respecting worth-play boundaries! 🥰 #siamese #kitten #Mondayisthenew #caturday

Not every #cichlid fish needs two parents! A Cyphotilapia frontosa female produced offspring in the absence of a male, with #genome-wide heterozygosity patterns consistent with self-fertilization. Amazing work by M. Efe Uysal with W. Salzburger and A. Marks Preprint: www.biorxiv.org/content/10.6...

Another beautiful day at the #RemoteOffice to go see the Cahaba Lilies! #Alabama 🌎🧪🏵

A great day at the remote office! #Alabama 🐟🌎🧪

Had some really good times in #MobileAL for the #GulfCon2026! It was great meeting so many new people and discussing new ideas and future collaborative work! 🧪🐟🌎

Here it starts! #GulfCon2026 #MobileAL 🧪🐟

Hopeful news for the US Antarctic research community? 🌎🧪🇦🇶🧊🐟 Trump seeks to jump-start long-planned Antarctic research icebreaker | Science | AAAS www.science.org/content/arti...

Thank you MSU Mississippi State #Wildlife, #Fisheries, and #Aquaculture Department and Mike Sandel for hosting me for the Spring 2026 #Conservation Seminar Series! 🌎🐟🧪🇦🇶 It was great meeting everyone and visiting the campus and the Aquaculture facilities! I hope to be back soon!

Beautiful essay on Beattle Bob and the Delta Smelt. I wish I had met them both 😕

Updating some of my ocean heat content graphics tonight with data for 2025, which required extending the y-axis upper limit and steepening the rate of the linear trend. Meanwhile just read another article describing declining newspaper coverage on climate change. So many feelings, all the time.

Fun time bringing some students of my Aquatic Biodiversity and Conservation course to the local Turkey Creek Nature Preserve to learn about endangered darter fish, turtles, bats, and more! Thank you for the tour and all the great explanations Jefferson County Greenway staff! 🌎🧪🐟 #UABbiology

Only one week left for abstracts to the @scar-antarctic.bsky.social SCAR Open Science Conference in Oslo this summer! Come share your fish evolution studies! 🇦🇶🧊🐟🌎🧪 @usscar-antarctic.bsky.social @mmatschiner.bsky.social #antarctica #TeamFish #FishSci

Only ~3 weeks left to submit abstracts to the @scar-antarctic.bsky.social meeting in Oslo! Come present your work on Antarctic and/or sub-Antarctic fish evolution in session#21 convened by @mmatschiner.bsky.social, Julia York, Jin-Hyoung Kim, and myself! All the fishes are welcome!❤️🐟🧪🌎🇦🇶 scar2026.org

Happy Friday night!

Those look like many Paragonotothen ramsayi! 🤩 It's one of the species whose Antarctic Notothenioidei ancestor readapted to life in more temperate waters and subsequently diversified in over a dozen species around Patagonia, thus the genus name Patagonotothen! 🧪🌎🐟🧊🇦🇶

Come tell us about your cool new evolutionary work on Antartic (and/or sub-Antarctic) fishes! It doesn't have to be notothenioids, we love all the fishes (and Evolution)!! 🧪🌎🐟🧊🇦🇶 @scar-antarctic.bsky.social @usscar-antarctic.bsky.social

For #AntarcticaDay, do you know the #fish that live in the frigid waters around the icy continent?! blogs.uoregon.edu/antarcticfis... 🧪🌍🇦🇶🐟🐠🐡🌊🐧🧊 #sciart #TeamFish

Awesome first day of talks at the 2025 Southeastern Fishes Council (SFC) in Tuscaloosa, AL! Great diversity of impressive student talks on the incredible fish biodiversity of the South! 🧪🌎🐟

The first international workshop that focused on #zebrafish was convened in 1990 in Eugene, Oregon. Sponsored by NIH and NSF, the gathering of ∼40 scientists sought to evaluate the research potential of the tiny fish. Today, nearly 1,800+ zebrafish labs exist worldwide. #ZebrafishFunFacts 🧪

I was recently interviewed by @sciencenews.bsky.social about the discovery of new Antarctic #fish nesting in the fragile Weddell Sea in #antarctica. This time it was the yellow fin notie Nototheniops nudifrons nesting, likely in groups! 🧪 🌎 🇦🇶 🐟 🧊 www.sciencenews.org/article/anta...

🚨 Recruiting 12 PhD students for a new NSF-funded program at the University of Alaska Fairbanks College of Fisheries and Ocean Sciences! This program is for U.S. students who received an Honorable Mention on the NSF GRFP within the last 3 years. @uafairbanks.bsky.social www.uaf.edu/cfos/academi...

@snbogan.bsky.social @notothentoma.bsky.social @scotthotaling.bsky.social @paulbfrandsen.bsky.social et al. explore the evolution of type III antifreeze proteins in deep sea zoarcoid fishes. 🔗 doi.org/10.1093/molbev/msaf219 #evobio #molbio

@notothentoma.bsky.social @arcolon14.bsky.social & @jpostlethwait.bsky.social show how Antarctic white-blooded icefishes, the only vertebrates without hemoglobin, independently lost hemoglobin cluster genes, driven by TEs and repeats. 🔗 doi.org/10.1093/gbe/evaf184 #genome #evolution #TEsky

Excited to share this work, out today in MBE! In polar fishes, we found that antifreeze protein genes expanded in copy number at low temperatures and contracted in the deep sea, highlighting a role of depth and pressure in AFP evolution. 🔗 academic.oup.com/mbe/article/...

IT'S ADORABLE! New fish species just dropped: the bumpy snailfish at 10,000 ft down in the ocean gift link: www.nytimes.com/2025/09/08/s...

First pop gen paper from our lab! We find repeated evolutionary turn over of sex chromosomes in darters contributes to reproductive isolation. Turnover may be an escape hatch to resolve mitonuclear conflict & neo sex chromosomes evolved via a rare recessive mutation. www.biorxiv.org/content/10.1...

Few months ago I commissioned artist @hidet0shi.bsky.social a drawing of the Antarctic dragonfish we described last year, with if possible both the fish and the RV Laurence M Gould as the fish was named after the ship: Akarotaxis gouldae! It turned out so beautiful I made stickers out it! 🧪🌎🐟🧊🇦🇶

While trying to see if two populations of the Antarctic longfin icedevil fish Aethotaxis mitopteryx were genetically differentiated, we uncovered a clear sex signal demonstrating that in this rarely encountered species males are the heterogametic sex! 🧪🐟🌎🐧🧊🧬 onlinelibrary.wiley.com/doi/10.1002/...

First "official" lab meeting in the books at UAB Biology! 🐟🧪🧬

Scientists have asked the NSF to reconsider plans to terminate the lease for its only Antarctic research icebreaker, the RVIB Nathaniel B. Palmer. eos.org/research-and...

The National Science Foundation plans to abruptly end operation of the RV Nathaniel B. Palmer, the sole U.S. research ship capable of braving the farthest reaches of Antarctica and the Southern Ocean. scim.ag/4mB8LOX

Environmental conditions influence life history traits, but what about in Antarctic fish?🐟🇦🇶 We compared two pops of Crowned Notothens Trematomus scotti: one from a fjord of the Antarctic Peninsula and one from the Weddell Sea. Their life histories traits were very different! tinyurl.com/mtmmrv8w 🧪🌎🐧

The Braasch Lab @fishevodevogeno.bsky.social will soon post a position to replace manager of our *Ancient Fish Facility* at Michigan State. Looking for aquaculturist excited for unusual 🐟 species (gar, bowfin, paddlefish, polypterus) + zebrafish. Pls send candidates our way (DM or [email protected])!

Snailfishes and their way to get their eggs protected in the gill cavities of crabs are so awesome!

My Bioinformatics Bootcamp turned blog! Enjoy this collection of free #zebrafish resources, now posted on @the-node.bsky.social. While not comprehensive, it gives an assortment of cools tools available to researchers. Feedback would be appreciated! thenode.biologists.com/bioinformati...

Happy #worldpenguinday y'all! 🐧🇦🇶 🧪🌎 Here's apparently the only penguin picture I have on my new computer 😅 It's an Adelie Penguin I image in 2014 at Prospect Point (Station J @bas.ac.uk) on the Western Antarctic Peninsula.
