🚨New paper out in PNAS🚨 Soil eDNA reflects regionally dominant species rather than local composition of tropical tree communities 🧬🌿🌳🌺🧬 We asked about the spatial scale of biodiversity captured by samples of DNA from tropical soils #Luquillo #eDNA. A short 🧵.... www.pnas.org/doi/10.1073/...

Our new work on estimation of background selection (BGS) is up on bioRxiv. We investigated the problem using simulations and also developed a method for joint inference of BGS, demography and partial selfing from windowed site frequency spectra along the genome. Feedback is welcome. #BGS

#PopGen New preprint of the team on the discovery of a very high rate of polymorphic duplication in a marine bivalve. Imagine looking at the distribution of the allelic coverage fraction at heterozygous calls in an indivdual and getting this distribution 👇 😱😱😱

🚨Registration open🚨 1st - 6th of June, me, Katie Jenike, @rayanchikhi.bsky.social and Gene Myers will run a week long workshop on k-mers for biodiversity genomics organised by @connectingscience.bsky.social at @sangerinstitute.bsky.social. Join us & get equipped to wrestle large genomic datasets!

My and Derek Setter's work on gene flow is now published in the latest issue of Genetics. We show that it is possible to detect past gene flow between two populations by summarising the asymmetry in pop-specific external branch lengths. 1/2 tinyurl.com/5ff8ch9e
