Beautiful work by @nadiahaghani.bsky.social and @mollyschumer.bsky.social on perhaps the most charismatic coloration trait in swordtails and platys!

Happy to share work spearheaded by former grad student Colin Shew testing shared duplicated cis regulatory elements (CREs) using an MPRA. While we find some high effect CREs, collectively paralog differences represent modest effects accounting for observed gene expression divergence.

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...

If you're attending #SMBE2025 check out graduate student @tododge.bsky.social 's talk at 11:30 am tomorrow (8:30 pacific time tonight if you're watching remotely). It's a wild ride with lots of complex structural variation, balancing selection, and introgression!

Increased rates of hybridization in swordtail fish are associated with water pollution
Biodiversity loss can occur when disturbance compromises the reproductive barriers between species, causing them to collapse into a single population through hybridization. Recent research has documen...

A project five years in the making, we've now published complete "T2T" genomes for six additional ape species! It turns out that finishing (and analyzing) six genomes is slightly more work than one... doi.org/10.1038/s415...

New NIH funded research from our group now out. We are interested in development and evolution of cell types and adult phenotypes. In this paper, postdoc Dylan Huang and collaborators asked how a pigmentary ornament of bright white cells develops on the fin of zebrafish. www.pnas.org/doi/10.1073/...
