I'm looking to hire a postdoc to work on the RepAdapt + MacroMar projects, analysing genomic data from >130 species of plants, animals, and fungi (VCFs are processed, ready to go). Lots of potential for creativity and collaboration! yeamanlab.weebly.com/uploads/5/7/...

Very excited about SimGEA: a method for detecting genomic signatures of local adaptation developed by Takahiro Sakamoto. Unlike previous methods, it achieves good control of the false discovery rate (on simulated data) while maintaining reasonable power www.biorxiv.org/content/10.6...
Figure showing the false discovery rate for simGEA (green), kendall's tau (red), LFMM2 (purple), and Baypass (blue). Kendall's tau involves uniformly high false discovery, as expected. Both LFMM2 and Baypass incur substantial false discovery rates (even above 50% in some scenarios). SimGEA achieves a well controlled false discovery rate across all scenarios we tested.

🚨Funding for 2yr postdoc w/ me & @geocron.bsky.social on landslide-tsunami-jökulhlaup project, but (this is the ridiculous part) I need to select someone NOW or I lose the $. If you're NOT in Canada (can be any nationality) and interested, send me your CV and transcripts by midnight MT, June 12. 🧪⚒️

Great to see Gabriele's paper out in MBE. I was really interested that we found large differences in ancestry maintained across opposite sides of a single valley (presumably with high gene flow). Strong divergent natural selection on cool/wet N-facing vs. hot/dry S-facing slopes.

I actually tell them this -- use it as a study aid, and if you're not confident you can assess what AI is saying as correct/incorrect, that's a sign you need to study that more

Sam Yeaman @samyeaman.bsky.social · 09/01/2026
Will it go away if we ignore it? We need to train them to think critically alongside it. Still trying to figure out how, but I don't see any viable alternative. Unfortunately, training them to use AI effectively requires small class sizes and lots of interaction, which nobody wants to pay for

Sam Yeaman @samyeaman.bsky.social · 08/01/2026
I think we want to push students to use AI competently. So if they're presenting, reduce the presentation time and increase the time where we ask questions and the students need to demonstrate comprehension and synthesis.

I'm doing regular practice writing assignments (minor participation marks for completion) throughout the term where AI can be used, and then an in-class writing assignment towards the end of the year, where AI will not be available.

Today 14 scientific societies in #ecology #evolution and #marineScience are publishing the results of a survey that finds negative impacts of federal policies on food security, flood mitigation, infectious disease preparedness, and wildlife conservation: 🧪👩‍🔬 www.firsthandaccounts.org/impacts/2025...
This infographic describes the main results from a survey of members of 14 scientific societies. There is a pie chart showing that both academic (58%) and non-academic (42%) responded to the survey. It lists statistics: 85% of respondents reported uncertainty about the future; 71% reported federal training programs were "very" or "extremely important"; 83% reported negative impacts or irreparable harm on their field of science. There is a word cloud summarizing open-ended responses with the largest words "student research fund federal grant". Eight major themes in the responses are listed: disruption of research with societal important; concerns of closure of the USGS Bird Banding Lab; Early Career Bottleneck; Restricted Freedoms including travel and speech; Decline in Government Efficiency and Expertise; Concerns about Biased/Removed Data and Data Gaps; Concerns about the Ability to Meet Legal Mandates; and From Positive Impact to Irreparable Harm. There are icons for each participating society and a QR code for website and data availability.

And this may generate perverse incentives. If I'm paid the same regardless of the quality of my review, then this incentivizes just submitting a "lowest possible effort" review. More hours for same pay = lower $/hour, making it feel like putting in the extra effort isn't worth it.

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?)
