We set out to investigate polygenic footprints of altitude adaptation in a moth species, but instead we uncovered a major selective sweep at genes often associated with insecticide resistance @prrnhd.bsky.social @schifanoalexandre.bsky.social @mgda76.bsky.social @cbgpmontpellier.bsky.social
A major selective sweep likely linked to insecticide resistance identified along altitudinal gradients in the pine processionary moth https://www.biorxiv.org/content/10.1101/2025.11.24.690095v1

Here we used population genomics to investigate a well-known case of allochronic divergence, reconstructing demographic history, assessing inbreeding and genetic load, and identifying loci associated with allochrony. @cbgpmontpellier.bsky.social
Population genomics of incipient allochronic divergence in the Pine Processionary Moth
Allochronic divergence is a key evolutionary mechanism that can frequently lead to incipient speciation. Although theoretical models suggest that such divergence is notably facilitated by small popula...
