I am very pleased to share with the mastodon community the first part of my PhD work:
High prevalence of Prdm9-independent recombination hotspots in placental #mammals
https://www.biorxiv.org/content/10.1101/2023.11.17.567540v1
This work was done in collaboration with @djivanprentout Alexandre Laverré, Théo Tricou and @duret_lbbe. (1/8)

High prevalence of Prdm9-independent recombination hotspots in placental mammals
In many mammals, recombination events are concentrated into hotspots directed by a sequence specific DNA-binding protein named Prdm9.bioRxiv

Ten years ago, with @cfraisserios, we were dissatisfied with averaging windows in genome scans and decided to calculate FST90 (the 90th percentile of the FST distribution) and FSTmax (the maximum FST of the window) instead. We struggled to convince the reviewers that this was a good idea. We now have a paper we can cite to justify that it's the right approach. Why FST90 in addition to FSTmax? Because in true data FSTmax is full of rotten SNPs. #PopGen

Weak genetic draft and the Lewontin's paradox
Neutral theory assumes that in a population of size N, diversity results from an equilibrium between new mutations arising at rate μ and genetic drift that purge them at rate 1/N, predicting an equilibrium value proportional to Nμ.bioRxiv

Quantifying the local adaptive landscape of a nascent bacterial community - Nature Communications
Fitness landscapes largely shape the dynamics of evolution, but it is unclear how they shift upon ecological diversification. By engineering genome-wide knockout libraries of a nascent bacterial community, Ascensao et al.Nature
