New paper out in #ES&T where we show that killifish exposure to crude oil has impacts (on embryo/larval development and transcriptome) that propagate to their offspring and to their grand-offspring. pubs.acs.org/doi/full/10....

BUT. These changes occurred in different parts of the genome: regions with high epigenetic change had low genetic change. However, the underlying "why" for this pattern we still don't know. Lots more work to be done!

We used 25 generations of experimental evolution to global change conditions in the copepod Acartia tonsa and found consistent genomic and epigenomic shifts within and between treatments.

If you're interested in the interaction between genetic and epigenetic changes during rapid adaptation, take a look at our recent paper in @pnas.org ! doi.org/10.1073/pnas...

Super excited to have this finally out!

Super excited to release a huge evolution project on the works for many years:

Evolution experiments synchronized across climates to understand rapid adaptation

How do fish evolve to tolerate higher temperatures, and are there trade-offs? We explore these questions in our new paper

Well we aren’t legally allowed to strike. So I would be fired. And I’m a scientist and my work isn’t public facing. So I’m not sure the effect this would have.

Yep. Good to check for sex chromosomes, inversions, etc. I think a nice thing to check generally.

New preprint out from postdoc Jenny Nascimento-Schulze! In hybrid blue mussels, the genetic contribution from different species dramatically shifted under heat selection. And this resulted in changes in performance. Maybe an approach to increase aquaculture resilience?

Our paper on allele frequency transitions under polygenic selection, with a focus on evolve & resequence experiments, is up at Genetics. Led by grad student Nathan Anderson:

We are removing the largest and longest-lived animals, which can be detrimental to those species dependent on migration, sociality, and cultural transmission to survive. Paper in Science by @kellerfish.bsky.social et al.: www.science.org/doi/10.1126/...

Hi! Please add me! Thanks!

Just posting this to #popgen
Here's a link to my notes on population & quantitative genetics:

Hoping to extend it more after the winter holidays, as I'm just finishing up teaching the undergrad version of class.
