For those interested, a new version (v3.1.0) of poolfstat is now on CRAN, including new functions and updates, new stats (Fh, Fd, FdM) implemented in sliding.windows.fstat; and a revised vignette.

Les insecticides pyréthroïdes impliqués dans la mortalité massive des papillons monarques sur un site d'hivernage en Californie : Une nouvelle étude évaluée par des pairs a établi un lien entre les pesticides et la mort massive de papillons monarques occidentaux survenue en 2024.
First paper from #TanguyMuller, PhD student in @cbgpmontpellier.bsky.social: Population genomics of incipient allochronic divergence in an infamous moth. #WGS #demography #inbreeding #mutation-load #genome-scan onlinelibrary.wiley.com/doi/10.1111/...
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
Point évoqué : stratégie d'accompagnent. Il dit "moi comme mes prédécesseurs avons harcelé les universités et organismes en leur disant bandes de nuls déposez plus". Mais quelle stratégie! quel meneur! 😂
"a major extension of SLiM’s capabilities for simulating
multiple chromosomes" 😍
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

The first chromosome-scale genome assembly for the Pine Processionary Moth - Thaumetopoea pityocampa: 615.9 Mb long, 50 chromosomes, recombination rate from 1.98 to 11.6 cM/Mb between chromosomes, 49.1% of repeats, 12,898 gene models. @mgda76.bsky.social @cbgpmontpellier.bsky.social
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
🚀 A new version of BayPass (v3.0) is now available for GEA/pGWAS analyses. This update brings support for Genotype-Likelihood data, hybrid datasets (allele counts and/or Pool-Seq and/or GL), or local-score computation (see updated manual).

Les insecticides, herbicides & fongicides affectent un large éventail d'espèces non ciblées et peuvent être liés à la perte de biodiversité à l'échelle mondiale. Une synthèse de 1 705 études donne une preuve supplémentaire de leur rôle dans l’effondrement du vivant.
