Why is phenotypic plasticity so common? Models show that even low migration between locally adapted populations can maintain costly plasticity in constant environments, revealing migration as a key driver of plastic trait evolution. academic.oup.com/evlett/advan...

Do extra chromosome sets mask bad mutations? Simulations show tetraploids often carry higher genetic load than diploids, depending on dominance, demography, and drift—with important implications for fitness and conservation. academic.oup.com/evlett/artic...

Can we predict gene expression evolution? In flour beetles, transcriptome-wide selection predicts expression change, with indirect selection acting strongest on pleiotropic, network-central genes—linking co-expression architecture to adaptation. academic.oup.com/evlett/artic... Photo: Udo Schmidt

My first manuscript reviewed by @peercommunityin.bsky.social (Evolutionary Biology) is now out in @peercomjournal.bsky.social, and I could not be happier with the processes. I am proud to contribute to what I believe is the future of scientific publishing. peercommunityjournal.org/articles/10....

"Biologists often become alienated from mathematics at an early stage in their career under the misconception [...] that biology is not a mathematical science. The claim is also often made that mathematical theory is overly simplistic, ignoring the [...] complex nature of biological systems." 1/

Why aren't more researchers publishing in society journals? Two potential reasons: 1) They're often unfamiliar to early-career researchers, and/or 2) they need better promotion, a task for all of us.

A good opinion piece from the EiC of FEE: esajournals.onlinelibrary.wiley.com/doi/10.1002/... I find society-owned journals more rigorous, and more supportive to the scientific community. Whenever possible, let's give society journals more support as well @esajournals.bsky.social.

Not sure this needs emphasis, but worried about overfitting in #data-driven models? #Theory-driven predictions based on principles offer transparent rationale. Assumptions, parameters & interconnections are easier to assess and refine - it's more about evaluating assumptions than fitting to data 🧪

The irony of performing science in grad school is executing the research itself isn’t the difficult part. Rather it’s the natural human flaws, opinions, politics and poor communication skills which impede our ability to do research or collaborate effectively in ways that produce effective science.

Physiology, the functioning of a cell at a given time and in a given set of physiochemical conditions, is an emergent property that cannot be reliably predicted from genomic data or metabolic reconstructions alone. #testthy(metagenomic)hypotheses

One year on, we’ve heard little reaction to our paper conceiving #species as process-bound, historical, and without natural rank. Integrative #taxonomy and #phylogenetics should love the concept; #speciation biology might not, but it could. #evolbio #philbio #philsci #hpbio
