Excited to share our new paper on genetic differentiation in Atlantic silversides! We investigated how genome structure influences adaptation under varying levels of gene flow using a species-specific reference genome and multiple recombination maps. Read on for insights! doi.org/10.1093/molb... 1/7
Genetic differentiation is constrained to chromosomal inversions and putative centromeres in locally adapted populations with higher gene flow
Abstract. The impact of genome structure on adaptation is a growing focus in evolutionary biology, revealing an important role for structural variation and

An important point getting overlooked:
When NIH cancels "diversity" grants (e.g., diversity supplements, Fs, Ks, etc), they aren't canceling the grants based on *what* the grant studies.
They're cancelling them based on *who* is doing the research. And that disallowed "who" is anyone not white.

A new tool, vcfsim, developed by Paimon Goulart, a stellar undergraduate researcher in my lab! vcfsim allows for the quick and easy simulation (via parameterized msprime simulations) of "all-sites" vcfs, with arbitrary ploidy and amounts of missing data.

vcfsim: flexible simulation of all-sites VCFs with missing data
VCFs are the most widely used data format for encoding genetic variation. By design, standard VCFs do not include data from sites where all individuals are homozygous for the reference allele ("invari...

@ksamuk.bsky.social pointed this out on the other site, but I don't see much discussion here.
GATK will now encode missing genotypes as "0/0", or homozygous ref, instead of "./." in VCF files. To identify sites with missing data, you'll have to check the DP field.
