Check out our new paper linking #genomics and #geology with #evolution in a group of freshwater #fish. Grateful to have played a small part in this exciting study led by @dkimfish.bsky.social , Dr. Maya Stokes, and @tjnear.bsky.social. doi.org/10.1093/evol...

Working with mitogenomes for eDNA, phylogenetics, etc, but not sure what's available on GenBank? Maybe your study group has weird mitogenome features? Come explore with with my new GenBankMitoReview tool! github.com/dmacguigan/G... #DNA #bioinformatics #eDNA #GenBank

Whoa, never thought I'd have research featured on Jeopardy!

@garlab.bsky.social -themed content on Jeopardy tonight! A 2024 study found that gars’ evolution was at a virtual standstill, at .00009 of THESE GENETIC CHANGES per million years… 🐟🦑☠️

Here’s the @jeopardyofficial.bsky.social GAR question based on our team’s living fossil study (led by @chasedbrownstein.bsky.social @dmacguig.bsky.social)!

Check out our new paper! We debut the #R package PhenoDelimit, a simple #ML approach to morphological species delimitation without a priori lineage assignment. Plus we describe a new darter species, 𝘼𝙡𝙡𝙤𝙝𝙞𝙨𝙩𝙞𝙪𝙢 𝙖𝙣𝙖𝙨, endemic to the Duck River system in TN. doi.org/10.1093/sysb... #fish #genomics

Genomic and Phenotypic Delimitation of Species in a Temperate Aquatic Biodiversity Hotspot

Abstract. Biologists have relied on morphological characteristics to identify, define, and formally describe species for the past 250 years. The advent of

I am very excited to share our new paper with my amazing co-authors and mentors @dmacguig.bsky.social @fishgenomes.bsky.social @tjnear.bsky.social . We investigate a secondary contact zone in #darters. track.smtpsendmail.com/9032119/c?p=...

Mosaic tri-lineage secondary contact shapes diverse genomic outcomes in darters

Abstract. Speciation does not always lead to complete reproductive isolation, which can result in hybrid zones with gene flow. In freshwater fishes, second

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 doi.org/10.1093/evol...

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. #hybridization #minnows #mudskippers

This is one of the most demented things Trump has posted

Check out our new preprint! We compare sequence versus synteny approaches for resolving a challenging #phylogenetic problem. In this case, synteny is far more informative! Also includes the first chromosome-level #genome for the enigmatic #fish family Gyrinocheilidae. doi.org/10.1101/2025...

In addition to the terminations of existing awards, new NSF grants are still stopped completely since DOGE was granted access to systems a week ago. Last Thursday, an agency spokesperson said "NSF continues to issue awards." That does not appear to be the case.

Thank you @sse-evolution.bsky.social! Thrilled to have our paper recognized.

I am beyond honored to announce that our paper (academic.oup.com/evolut/artic...) revealing a molecular mechanism of evolutionary stasis has won the @sse-evolution.bsky.social President's Award This work would have been impossible w/o my colleagues @tjnear.bsky.social lab and beyond!

A source just told me over the phone that layoffs are happening right now at NOAA. Axios is also reporting this. www.axios.com/2025/02/27/l...

Layoffs hit federal climate, weather agency NOAA

The cuts could affect NOAA's weather forecasts, climate research and other functions.

USAID staff have two days to clean out their offices at the agency’s former headquarters in DC. People are gathering on the sidewalk in the rain to show their support, applauding workers as they pass by.

“They apparently just sort of walked past security and said: ‘Get out of my way,’ and they’re looking for access for the IT systems, as they have in other agencies,” said a former Noaa official. “They will have access to the entire computer system, a lot of which is confidential information.”

Members reportedly sought access to IT systems at agency that Project 2025 has called ‘harmful to US prosperity’

I hope federally funded scientists are preparing for large scale, bad faith attacks by Musk and his troll army. It’s pretty clear the DOGE operation is going to take snippets of grant proposals and papers, present them out of context, and direct weaponized harassment of individual people.

Elon Musk takes far more federal dollars with far less oversight than any of the public scientists facing attacks. People who come under attack should respond by making sure anyone listening knows how much federal money Musk makes, and how he shields it from scrutiny.
