❄️🧬 Can we generate high-quality reference genomes without the cold chain? A new study suggests the answer is yes. DNA preserved at room temperature for up to one week produced chromosome-scale reference genomes. 📖 tinyurl.com/3zwtj9ka #Genomes @gigascience.bsky.social @sangerinstitute.bsky.social

Did you know you can find all the Variant Effects Seminars on the AVE YouTube channel? Established in 2021, the seminar series reached its 100 speaker milestone last month. So, there are plenty of great talks to choose from. Find your next watch: tinyurl.com/AVE-VESS #AtlasOfVariantEffects

Hey team - it’s looking very likely that I’ll be hiring not one but two four year postdocs! We’re a fun lab with tons of theoretical and applied pop gen projects - broadly in polyploid, conservation, and human evo. Competitive salary, sunny San Diego! Do share with your about to defend grads!

Cool Sankey diagram of the ranked choice voting results of Maine’s Democratic gubernatorial primary. Think how transformative this could be if more states adopted it.

A big congratulations to @littlemuseums.bsky.social for successfully defending her dissertation: Disentangling Evolutionary Signals to Diagnose and Address Conservation Need in Bears. #proudadvisor

I am recruiting a PhD student (fully funded, 4yrs) to analyze modern 🧬 and ancient 🦴 genomic data from humans and domestic animals 🐑 Please share, I am happy to chat at #ICP2026 or #SMBE2026 this summer www.uu.se/en/about-uu/...

It's so wild to me that ThermoFisher advertises to me via YouTube ads while I watch absolute pop culture garbage junk. Like Fisher, we're good, I promise I will get cell culture plates from you, literally ordered them last week

Thanks to @eepuckett.bsky.social , faculty and grad students in the Department of Biology at University of Memphis for an awesome visit! It was an absolute blast thinking about cool new synergies to complement research ideas. Fantastic visit to reinvigorate creativity!! With homage to Tiger Elvis ❤️

New preprint! We sequenced 175 'Alalā (Hawaiian crow) genomes to understand why >50% of eggs fail to hatch in a species recovered from just 9 individuals. What we found was a both exciting and surprising. www.biorxiv.org/content/10.6...

Male biased gene flow from N to S genetically rescued the S-Scandinavian brown bear population after a bottleneck caused by human persecution. 🦊 #Consgen

It’s always been a mystery to me how the genetic diversity and composition of the Scandinavian brown bear originated 🤔 Today, we publish a new paper that sheds new light on this, and a real-time example of how mito-nuclear discordances can evolve during severe bottlenecks: doi.org/10.1098/rsos...

It's World Bear Day (every day) around here. 🐻 🐻 From their floofy beginnings to their current state of affairs (fiercely floofy) brown bears Fern and Juniper are simply the best. #worldbearday

On #WorldBearDay, our 5-year-old polar bear Laerke is making a splash! From playful swims to floating on her back with a massive stick. Enrichment like this helps keep Lærke active, engaged, and mentally stimulated. 🐻‍❄️ 📹: Animal care staff Russell

Happy #WorldBearDay 🐻 This ⁠image is the winner of the Instagram category of our 2025 Northwest Exposure photo contest. Hiker Jolena Tagg was in search of wildflowers near Lake Eleanor when she came across this black bear.

Happy World Bear Day! Today we celebrate the important part that bears play in our ecosystems and highlight the challenges they face. Learn about how climate change impacts polar bears and conservation concerns for the world's largest bear species. pbears.org/conservation-concerns

Conservation Concerns | Polar Bears International

Climate change is the main threat to polar bears. Others include commercial activities, pollution, and conflict.

March 23rd is #WorldBearDay! 🐻‍❄️ 🐻 🐼 Six of the eight bear species are classified “vulnerable” by the IUCN. This means they are at risk of becoming endangered or extinct in the wild if threats to its survival persist. Follow IBA or donate to help us conserve #bears 👉🏼 bearbiology.org

Today on #WorldBearDay, we celebrate Colorado’s bears—resilient, intelligent, and vital to our ecosystems. By working closely with local communities, we’re reducing bear-human conflicts and helping wildlife and people coexist safely.

Happy #WorldBearDay. Manitoba is home to all 3 North American bear species, but I've only seen two. Black bears are common throughout the province, while polar bears roam the Hudson Bay coast. Barren ground grizzlies also show up occasionally on the coast. It would be amazing to see one. #mammals

(1/7) Hopping on the #WorldBearDay hype to share some of my dissertation work with @eepuckett.bsky.social. Here’s the dirt on Louisiana bears (the only Ursus americanus subspecies thats been federally listed through the ESA) doi.org/10.64898/202...

Can you spot the polar bear? They often dig 'day beds' by scooping out gravel and sand, making them even harder to spot when hiking along the coast. #InternationalPolarBearDay

Heather is right, meeting our @uofmemphis.bsky.social colleagues who are experts in lower Miss. River fluvial geomorphology (Randy Cox) and Late Woodland cultures (David Dye) was a highlight of writing this paper.

Heather Clendenin🐾🧬@littlemuseums.bsky.social · 5mo ago

My personal humble-brag for this paper: We tracked down an archeological expert on the time/region of a precolonial bottleneck we detected (Hi, Dr. Dye!). After synthesizing a LOT of lit outside my comfort zone, his feedback on the relevant writing was to add the word “increasingly” to a sentence🤓💅

I was not consulted and as such cannot verify the quality of this article.

Emily Puckett@eepuckett.bsky.social · 5mo ago

🐻Excited that my and @littlemuseums.bsky.social 's paper on the demographic history of American black bears across the eastern range is up! While I think the phylogeography aspects are interesting, our key point is that named subspecies are unsupported. doi.org/10.64898/202...
