This is today!

Enjoy some Bluesky positive vibes (sound on👍) from these juvenile Lake Sturgeon @garlab.bsky.social!

Congrats to @pfschwarz.bsky.social on publishing her undergraduate honors thesis work on darter hybridization! There is evidence of ecological specialization of two sister species. She also compares lcWGS and RAD-seq data for the same samples and finds tighter distribution of Fst estimates w/ lcWGS

It's not an o-fish-al #25DaysofFishmas til we get a coregonine! 🐟🎉 #ciscoinferno🔥

Nice paper on the other bloom in Lake Erie: diatoms. 👏 aslopubs.onlinelibrary.wiley.com/doi/full/10....

Before farms and suburbs, the Great Black Swamp thrived. Restoring it could help curb Lake Erie’s harmful algal blooms today. www.greatlakesnow.org/2025/11/the-...

A Sharon Begley byline, almost 5 years after her death. Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written." Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating. 🧪🧬🧫

Great to see new work lead by @pjflood.bsky.social out in @globalchangebio.bsky.social this week. Another piece from our collaboration with @michigandnr.bsky.social examining recently digitized historical lake survey data. news.umich.edu/fishes-young...

"The Great Lakes Science Center in Michigan would lose 108 of 137 positions." via @eenews.bsky.social

Court document reveals that the USGS Ecosystems Mission Area would be cut severely, and maybe entirely, along with critical natural resource management staff. This would be devastating for our public lands!

Speechless. A fisheries science center that has a 100 year history in Ann Arbor.

New paper alert! Not yet formatted, but check it out to see what we found regarding sex chromosomes in tilapia and other outgroup cichlid species. academic.oup.com/gbe/advance-...

A very appropriate theme today! Deepwater cisco species are sampled by trawling. This is Coregonus nigripinnis, one of the biggest ciscos and some of their scales that I sampled from the archive today dating back to the 60s

The 2025-26 Eco-Evo job list is out. Good luck to those applying! docs.google.com/spreadsheets...

Our review on the last decade+ of hybrid incompatibility research is now out! www.sciencedirect.com/science/arti... Original thread here: bsky.app/profile/moll...

Been waiting on a hamlet phylogeny (Hypoplectrus spp.) They have a beautiful mating ritual where they loop around each other floating up - then go down switch sexes and do the dance again. Also notable / 300+ genomes can’t resolve the relationships of 19 species! www.science.org/doi/10.1126/...

Frog Bay Tribal National Park along Lake Superior (established by Red Cliff Band in 2012) was the first of its kind. Other Tribes have since followed with similar parks. #GreatLakes #Indigenous www.wpr.org/news/lake-su...

Final read through of revisions and response to reviewer comments is done for the tilapia manuscript so look out for that here shortly! This was a hard one to pull together and Tom and I put it off for a while to do other things, so I’m glad to finally have it out of my hair.

"Like lobster to Maine and salmon to Alaska, whitefish is one of the signature animals in Michigan's history" But after decades of slow decline, the fish are now on the brink of collapse in most of Lakes Michigan + Huron in part due to invasive mussels #GreatLakes www.bridgemi.com/michigan-env...

Today is 🪸 Coral Triangle Day! DYK the #Philippines is one of 6 countries in this global epicenter of marine biodiversity? I was lucky to see this pair of mating Olive Ridley #seaturtles during a survey of Iliana Bay (a.k.a. Iranun Bay) 🇵🇭 last April with BALYENA.ORG

Check out our new preprint where we identify a large haplotype block associated with climate and smoltification in Atlantic salmon 🐟

What do endangered fish, schoolkids, and a conservation video game have in common? Dr. Trevor Pitcher. Meet the scientist blending lab work with storytelling, policy, and play to protect Canada’s freshwater species. Read his story on the #CSPBlog 💡▶️ buff.ly/jxWfLkl @pitcherlab.bsky.social‬

It's unbelievable to me that the jobs of USGS scientists—who are essential to understanding and protecting fish and fisheries—are at risk. Their work is absolutely critical.

All of the USGS ecosystems folks I know are amazing scientists and humans. The Great Lakes and their fishes would be lost without them

Fam — here’s a nice overview of the 43 nationwide Cooperative Fish & Wildlife Research Units, which have been a lasting model for wildlife research since the 1930s, created by wildlife science pioneers such as Aldo Leopold & Ding Darling. 🐟🦌🦆🦃🦎 Link: wildlifemanagement.institute/outdoor-news...

The USGS Ecosystems Mission Area, the foundation of the science that informs fish and wildlife management, disease response, and conservation policy across the U.S., is at risk. We're joining @nationalwildlife.bsky.social in a virtual rally on May 22 - register now: www.mobilize.us/nwf/event/79...

The USGS coop units are so essential to fish and wildlife management/conservation. I have been so lucky to work with these talented and dedicated researchers over the years, and am beyond sad and infuriated about these proposed cuts.

It looks like the Trump administration isn't going to wait for the FY26 budget to decimate the National Park Service and the USGS Ecosystems Mission Area. Thousands of job cuts (1,500 in NPS and 1,000 in USGS) are planned via reduction in force within 10 days. Who benefits from this? Not Americans.

A light in the midst of a lot of chaos and uncertainty in #GreatLakes science- Using genetics and morphology, we discovered a fish that was once presumed extinct still swims in Lake Superior. #CiscoInferno🔥 🐟🧬 www.biorxiv.org/content/10.1...

Quick break from the doom and gloom for science! We're really proud of this one. We found that two major effect loci on duplicated versions of the same ancestral chromosome play a major role in run timing diversity across four species of salmon (pink, chum, sockeye, coho) shorturl.at/GISX2

This is includes the Great Lakes Science Center and would be absolutely devastating to #GreatLakes fishery science.

1/ "Just do a quick analysis." If you're a bioinformatician, you've heard this before. But here's the truth 👇

One of the greatest honors I have ever had in my life! This is a very timely encouragement for me to further navigate my academic journey. I will always try my best to continue Dr. Bernatchez’s legacy. I hope this serves as a springboard that proples me to greater heights in the future!!!🙌

Wrapped up 2 weeks of overnight drift netting for larval Lake Whitefish on the Jordan River. Thankful for our phenomenal partners from the Little Traverse Bay Band & Sault Tribe, as well as my TNC colleagues. And thanks to Nick Mead and Leanne Chadwick for the great photos! #GreatLakes

Aquatic geneticist position in Lamar, PA at USFWS! #consgen

Opted outside to celebrate the New Year with snow geese, blue skies, and 40 mph winds at Blackwater National Wildlife Refuge. Happy 2025 all!

An intriguing new evolutionary story has just dropped, from my friend and colleague Leif Andersson: a discrete population of large predatory herring in the Baltic Sea, apparently in the process of evolving into a new species. 🧪 www.nature.com/articles/s41...

It’s #Festivus, so you know what that means - time for an Airing of Grievances about a #GreatLakes Grinch! Goldfish (Carassius auratus) - yes, the goldfish of home aquariums worldwide - have unfortunately been an invasive species in the #GreatLakes for decades #25DaysofFishmas

LAST DAY for #IAGLR25 abstract submissions. Get yours in now before the abstract proposal portal closes tonight. Just a reminder, the #GreatLakesSci conference is hybrid with flexible presentation options. For more information: bit.ly/3UPFRih
