First documentation of putative mating behavior in blue sharks (Prionace glauca) reveals a potential reproductive area in the Northeast Atlantic Abstract. Reproductive behavior in sharks remains poorly understood, with direct observations of mating reported in only a few species. The blue shark (Prionace glauca) is a widely distributed, placen...

First documented mating behaviour in blue shark. That's a nice one! #elasmo #sharkscience #marineconservation

#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 👇 😱😱😱

EMIBD9: Estimating 9 condensed IBD coefficients, inbreeding and relatedness from marker genotypes - Heredity Heredity - EMIBD9: Estimating 9 condensed IBD coefficients, inbreeding and relatedness from marker genotypes

New #popgen tools I found that use a likelihood method to mitigate small sample size problem when calculating IBD that can be great for #consgen purposes: www.nature.com/articles/s41...

This has Windows implementation as well as Linux and Mac! Let me know if anyone has tried this :D

Long runs of homozygosity are reliable genomic markers of inbreeding depression A long-standing goal in ecological, evolutionary, and conservation genetics is to identify genomic correlates of fitness and inbreeding depression. Over the past several years, a growing body of theor...

Effective Population Size Estimation in Large Marine Populations: Considering Current Challenges and Opportunities When Simulating Large Data Sets With High‐Density Genomic Information Next-generation-sequencing has broadened perspectives regarding the estimation of the effective population size (Ne) by providing high-density genomic information. These technologies have expanded da...

Happy to share our new review, led by Chrystelle Delord, Natacha Nikolic, @sofarndhnd.bsky.social and other people not on bluesky, about the Ne estimation in large marine populations, plus a simulation framework onlinelibrary.wiley.com/doi/10.1111/...

It has been since its first use in 1950, so confusing!
Here is our attempt to clarify and organize this concept in population genetics: www.nature.com/articles/s41...

How Microplastics Are Threatening Shark Reproduction Microplastics are accumulating in sharks’ gonads and GI tracts, disrupting reproduction and threatening population recovery.

How Microplastics Are Threatening Shark Reproduction

Forbes column from #shark researcher @melissacmarquez.bsky.social: a study of spadenose sharks on #India 's West coast finds microplastics "...in every water sample collected, 97.9% of GI tract samples and 95% of gonadal tissues."

Published version of our spatial simulations paper led by Jiseon Min and Elsie Chevy is up 🔐! This was such a fun paper to be a part of and a valuable resource to folks thinking population simulations of all kinds, even non-genetic ones! onlinelibrary.wiley.com/doi/epdf/10....

Like many of you, I have very strong, negative opinions about the current state of affairs, and I discuss those grievances with people daily. On this platform, I would like to share a very useful data analysis workflow that I've found in the effort of better transparency and reproducibility🧵:
