This was an amazing project to be a part of! Led by Hildegard Uecker and Matt Osmond, and including a bunch of awesome people.

Please repost! We are looking for two field technicians to work on our deer mouse project in the Colorado Rockies this spring-fall. Learn about physiology, ecology, and evolution, all in one project! Not to mention that you get to be in the ⛰️. Reach out if you have any questions.

Excited for this. Teaching popgen is one of my favourite parts of my job and I've wondered about doing an online version of the class for sometime. Teaming up with @jrossibarra.bsky.social to do this is wonderful.

NEW: ICE has a plan to lease offices across the US as part of a secret, months-long expansion campaign. Today, @wired.com is publishing dozens of those locations. Many are near schools, medical offices, and places of worship. Vital work from @leahfeiger.bsky.social that I'm proud to publish.

Gideon Mantell published his description of the iguanodon OTD in 1825. He had originally thought that the fossil teeth on which he based his description were those of a giant crocodile, but later determined that the creature was an enormous herbivore. 🐋🌱🗃️❤️🧪 #HistSTM

I am looking for examples of a 2-3 hour lab activity for a course that would allow college students to get some experience connected to environmental DNA studies (e.g., e-DNA, rRNA/ITS PCR, metagenomics, etc). Ideally this would have some DNA extraction and some follow up processing / analysis.

We're excited to be recruiting an NSF funded postdoc to work in the Villanea lab at CU Boulder. We're specifically interested in candidates who want to work at the intersection of population genetics, ancient DNA, and computer modeling. Please RT jobs.colorado.edu/jobs/JobDeta...

Fun news! @gcbias.bsky.social and I are teaching a 2-week online population genetics workshop this summer to raise money for the Center for Population Biology at UC Davis. We're trying to gauge interest -- please fill this out if you might be interested! And please share broadly!

Why is there such variation in the birds encountered as you go up or down a mountain? New paper in #ScienceAdvances examines how climate and ecological interactions drive bird distributions in mountains throughout the year: www.science.org/doi/10.1126/... 1/10 ⬇️

So cool. Multiple cell lineages contribute to the germline in maize -- and differences between apical and lateral branches! www.biorxiv.org/content/10.6...

Can’t say I expected to do a foray into linguistics during my PhD - a fun study collaborating with Sam and many passionate undergrads (who have gone on to do incredible things of their own!) I will have a poster at MGC later this month on this work - stop by and chat about it with me!

This paper is a great for teaching phylogenetic trees. "Ancient DNA reveals elephant birds and kiwi are sister taxa and clarifies ratite bird evolution" Clearly written. It discusses hypotheses of relatedness among species via continental drift vs genetic data. 🧪 www.science.org/doi/10.1126/...

Excellent classification. xkcd.com/3204/

New paper! From Sam Snodgrass and @genomeofforrest.bsky.social, w/ @druncie.bsky.social, @gcbias.bsky.social, and a collaboration with Andres Moreno and @santiagogmm.bsky.social. Can we quantify the impact of humans on maize dispersal? Plant yourself in a comfy chair and lend me your ear: 1/10

Cool backstory to this paper: it started as an REU project with co-author Luke Sparreo. Luke was one of those students who makes you work hard because he finishes your 7-week stretch goal in week 1. He did a lot of the work on connecting language phylogenies to maps. Come join this REU!

“Our findings suggest the capacity to form secondary representations of pretend objects is within the cognitive potential of, at least, an enculturated ape & likely dates back 6-9 million years, to our common evolutionary ancestors.” Amalia Bastos & @chriskrupenye.bsky.social today in @science.org.🧪

Just discovered the wonderful covers of 'Genes to Cells', the journal of the Molecular Biology Society of Japan @mbsj-official.bsky.social – absolutely beautiful! here some examples inspired by mitosis, CRISPR, the DNA helix, and plant pigments

New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects. www.nature.com/articles/s44...

Over 1,200 miles in the car this weekend, to and from the far corners of Kansas. Up by 5 and home after midnight, making every hour count: tabling with the party, meeting supporters, lecturing on negotiation strategy, and seeing a bald eagle strike. God, I love Kansas.

It might only be the first of February, but the birds are already building. This little pair of bushtits (Psaltriparus minimus) are bringing in regular deliveries of lichen & fluff to line & camouflage their nest in the silk tassel tree (Garrya elliptica).
