It's always fun to work with Tom! In this one, we ponder how the answer to this question can tells us something about the kind of architecture underlying adaptation

Check out this short piece on the genomics of local adaptation. Abi Brown (not on Bluesky) and I wrote it with @samyeaman.bsky.social

Any input you say have would be welcomed!

What fraction of the genomic basis of local adaptation are we missing?

I'll start reviewing applications in a little over 3 weeks for this PhD position. You could be doing fieldwork here! (or focus only on dry lab work if that floats your boat)

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.

I'm looking to recruit a PhD student to study patterns of local adaptation and introgression across the spruce hybrid zone in the Rockies near Calgary. Projects can include field work, bioinformatics, pop gen theory, or comparison to plant/ conifer species

Really great to see this out -- and so interesting to see strong signals of adaptation to North vs. South facing slopes across a single valley in spruce!

k-mer-based diversity scales with population size proxies more than nucleotide diversity in a meta-analysis of 98 plant species

Abstract. A key prediction of neutral theory is that the level of genetic diversity in a population should scale with population size. However, as was note

Temperatures are soaring, and there's a limit to what plants can handle. Scientists are figuring out how to engineer crops to take the heat so they can get into the kitchen.

If your grant application needs some justification on why we should study adaptation in wild plant species... www.science.org/doi/10.1126/...

Can wild plant adaptations help crops tolerate heat?

Wild plant species harbor a vast but largely unknown diversity of temperature stress solutions

People are currently running the analysis -- certainly some of the datasets are poolseq and we will be including those too, but at present I think we haven't finalized the pipeline. If you can email me at [email protected] I can send you some more info

Sam Yeaman @samyeaman.bsky.social · May 11

Great! What species are you working on? If you can email me at [email protected] I can follow up with more info.

Sam Yeaman @samyeaman.bsky.social · May 11

Glad you're interested! Yes, there is a separate set of methods for that -- is this in threespine stickleback? There are quite a few people already involved and working on collecting stickleback resources. Or is it another species?

Sam Yeaman @samyeaman.bsky.social · May 8

Are you interested in the genomic basis of repeated adaptation? The RepAdapt group now has >70 members working to re-run their whole genome shotgun datasets through a common SNP calling pipeline, sharing VCFs, and working together to analyse data. Please contact me if you'd like to contribute!

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.

Emmett Macfarlane 🇨🇦 @emmettmacfarlane.com · Mar 31

Some colleagues hate when I point this out, but for tenured/tenure-track faculty, peer review is already compensated work. It is part of the 20% of our jobs that account for service (in 'standard load' positions).

Angie Rasmussen @angierasmussen.bsky.social · Mar 31

Peer review is essential to robust, reproducible science. Peer review is work. Work should be compensated. Period.

But these costs should not be assumed by the authors. Publishers are making record profits & should invest that in their own products.
