New research by @tylervkent.bsky.social @samurscicop.bsky.social & D. Matute analysed 131 genomes of the globally invasive Aedes aegypti, and found high genomic resilience despite historical eradication attempts for this globally invasive vector. 🔗 doi.org/10.1093/gbe/... #genome #mosquitoes
Demographic History, Genetic Load, and the Efficacy of Selection in the Globally Invasive Mosquito Aedes aegypti
Abstract. Aedes aegypti is the main vector species of yellow fever, dengue, Zika, and chikungunya. The species is originally from Africa but has experience

Selection against dispersers: sex, age and origin-dependent fitness differences in wild Atlantic salmon
Abstract. Local adaptation is often portrayed as uniform fitness disadvantages of immigrants relative to locals. Yet dispersal costs vary with origin, sex

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
For those interested: 🚀 BayPass v3.1 released! 🔹 Improved MCMC adaptive phase 🔹 Computation reduced >6X with default (recommended) options, while keeping similar accuracy 🔹 Plus other minor edits 📖 Details in the manual / changelog 🔗 Repo: forge.inrae.fr/mathieu.gaut...

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...
