Our paper on the genome assembly and annotation of the Antarctic bald notothen (Trematomus borchgrevinki) is now available in G3!
This paper was lead by @niraj-rayamajhi.bsky.social, in collaboration with Bushra Fazal Minhas, Chris Cheng, and @jcatchen.bsky.social.

Do you know anyone with an interest in pursuing a PhD studying the genetics, development, and evolution of skeletal morphology and life history? If so please encourage them to apply to work with me through any of the University of Illinois' EEB or PEEC programs. 1/4 🧪🦷🦴🐭🐒

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...
Top left: Results of genome-wide association study (GWAS) for sex in E. caeruleum, E. radiosum, and E. spectabile showing sex chromosome turnover has occurred repeatedly. Top right: Phylogeny showing sex chromosome turnover in darters and non-darter percids. Chromosome 9 is the putative ancestral sex chromosome, shared by Perca flavescens and multiple members of the orangethroat darter complex (e.g., E. spectabile, E. pulchellum). Bottom: Schematic depicting repeated turnover of sex chromosomes as a mechanism to resolve mitonuclear conflict and promote speciation.

The new XKCD has to be a reference to the ant paper where ants just casually lay eggs of a different species, yes? Maybe? There are so many weird bugs its hard to know.

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!

OrthoFinder just dropped a major update

It’s faster, more accurate, and ready for thousands of genomes

@ramencult.bsky.social et al. use spatially explicit simulations and genomic data from Anopheles gambiae, showing that selection changes the joint distribution of allele frequency and geographic range.

Do you want to learn about how very large populations evolve? Do you think barnacles are super cool? Come check out my talk on Saturday morning's Population Genomics session at #Evol2025!

Excited to attend my first Evolution meeting in a few years. Check out my #Evol2025 on Tuesday June 24 11:30-11:45 in Comparative Biology I (room Athena GH) on detecting shifts in selection in multicopy gene families as applied to vertebrate genome evolution.

Crazy times, but I'll be advertising for a 2 year postdoc to work with me on new comp. methods to estimate evolutionary history soon - specifically to develop methods to handle missing data (e.g. ascertainment bias, allele dropout). Are you a comp. biologist graduating with a PhD soon? Reach out!
