We had our 40th annual Darwin Lecture last Friday at University of Calgary, given by @jrossibarra.bsky.social and it was a banger! If you have a big public lecture, he gives a great one...Thanks again for coming Jeff!

Join us in Tuscany this summer for a Gordon Conference aimed at the cutting edge of how we use genomics to answer fundamental questions in ecology and evolution! Lots of great speakers already and we'd love to add you to the list www.grc.org/ecological-a...

Thanks yes I've been meaning to test this one on our datasets, haven't gotten around to it yet. Nice idea! Will work on this

Yes we tried pSONIC and found it improved things calls over short phylogenetic distances (e.g. within brassicas), but not much over larger ones (probably because of extensive rearrangement?)

What is state-of-the-art for orthology inference? Anything in the works we should be watching for? Have been using orthofinder2 and most interested in maximizing accuracy and number of genes with calls (not computation speed). Methods incorporating alpha-fold predictions? Synteny/collinearity?

New plant adaptation research from @samyeaman.bsky.social and his team: ucalgary.ca/news/plant-a...

Compare these results with Jim Whiting's paper on genes with signatures of repeated local adaptation, where they tended to be more central in co-expression networks (high pleiotropy), also consistent with migration-selection theory!! www.nature.com/articles/s41...

Gabriele's paper is out in PNAS! He found a large number of genes with repeated sweeps in multiple plant species. Most interestingly: they tend to be peripheral in co-expression networks (low pleiotropy), consistent with mig-sel theory!! @gabnocgenomics.bsky.social www.pnas.org/doi/10.1073/...

I’m proud to join more than 30 colleagues today in sharing our analysis of potential risks from “mirror life”. We summarize our findings in a @science.org article, and in greater detail in a 300pg technical report: Article: www.science.org/doi/10.1126/... Report: purl.stanford.edu/cv716pj4036

I'm looking for a new grad student interested in microbiology of ancient groundwaters, a fascinating journey into an enigmatic environment with opportunities for fundamental discovery and relevance to groundwater remediation. Contact me if you like fieldwork, mesocosm experiments and metagenomics.

Grads & Postdocs: interested in the Speciation Gordon Research Conference www.grc.org/speciation-c..., and Symposium www.grc.org/speciation-g...? We will give registration vouchers to a random set of grads/pdocs who register before Nov 24 ($300 if traveling from North America, $500 from outside)

Wow, there is suddenly a tidal wave of new users. Great to see! Maybe this site is finally getting some momentum. As problematic as even the old pre-Musk twitter was, it was very useful and current-twitter/x is a dumpster fire.

Please share widely: The 2025 Speciation Gordon Research Conference (March 2-7 2025) is now open for registration to anyone. If you wish to attend, apply here: www.grc.org/speciation-c... Attendees can present posters, and there are a couple open talk slots to be filled from poster abstracts.

I'm organizing a working group on the genetic basis of repeated adaptation, by zoom on October 22nd. Broad aim: use common methods to identify genes driving adaptation across many species of plants and animals. Please contact me for details! yeamanlab.weebly.com/repadapt.html

Takahiro Sakamoto used a creative approach to derive the threshold per-trait mutation rate where local adaptation shifts from a stable to transient genetic architecture. The prevalanece of stable architectures in nature implies small mutational target size academic.oup.com/genetics/adv...

I'm recruiting for a PhD position to study the genomic basis of repeated adaptation at the University of Calgary. We have a big multi-species dataset and aim to expand it, with many unexplored avenues to test fundamental theories of evolution yeamanlab.weebly.com/uploads/5/7/...

Now in press: Local adaptation in 25 distantly-related plant species tends to involve genes with higher pleiotropy rdcu.be/dR0r6 With global adaptation, we found the opposite pattern (reduced pleiotropy), consistent with migration-selection theory www.biorxiv.org/content/10.1...

Really excited: Takahiro Sakamoto derived the threshold for mutations to overwhelm local adaptation and collapse a stable polymorphism to a transient architecture. Requires a big mutational target, helps explain variation in observed architectures of local adaptation www.biorxiv.org/content/10.1...

New results from comparative population genomics: Genes driving global adaptation -> low pleiotropy; genes driving local adaptation -> high pleiotropy. Consistent with migration-selection theory. Great work from Gabriele Nocchi and Jim Whiting www.biorxiv.org/content/10.1...
