New #phylogeography preprint is out, just in time for the holidays! Here we explore glacial lineages, mito-nuclear discordance and local ancestry tract detection using low-coverage WGS (2X), all in Arctic Char of course! 🐟🏔️ @jeansebmoore.bsky.social @michaelmhansen.bsky.social #PopGen
Local ancestry inferred through local PCA. Fig. 5 on the manuscript : Representative case of a low-recombining diverged putative haploblock corresponding to a local PCA outlier region (win8) on LG9 (NC_036849.1). a) Position of the MDS outlier region (red) on the linkage group (above) and standardized PC1 coordinates in PCAs for successive non-overlapping 100-SNP windows inside and around the outlier region (below). Each sample is represented by a line colored according to their haplogroup inferred from panel b). b). PCA for SNPs in the outlier region where the three major clusters found on PC1 are attributed to the 2 homozygotes (AA, blue, left; BB, yellow, right) and their heterozygote (AB, green, middle). Intermediate genotypes (A0, light blue; 0B, light green) were assigned to individuals outside of the cluster distributions. The histogram (above) represents the density of individuals along the first axis of the PCA. c) Proportion of inferred haplogroups for the win8 haploblock across sampling sites.

Good ocean news 🌊 Wisdom the Laysan albatross (the oldest known bird) laid another egg 🥚 It's been 4 years since her previous partner, Akeakamai, disappeared. Now she has a new mate and they've just become parents. We'll know early 2025 if their egg safely hatches 🦑🧪🌊 www.forbes.com/sites/amanda...

Wisdom the albatross returned to Midway Atoll with a new mate and her first egg in years. The long-lived seabird is still alive and is estimated to be 74 years old.

New paper by @roberta-gargiulo.bsky.social on extinction debts and #popgen. A bottleneck test is also a test for a genetic extinction debt 1/ at mutation-drift equilibrium Ne predicts allelic richness AR and gene diversity He and vice versa

3/ An extinction debt also occurs when gene flow in a metapopulation drops below 1 MPG. This doesn't reflect a deviation from mutation-drift equilibrium, but from migration-drift equilibrium in the metapop. A drop in gene flow reduces the realized inbreeding Ne of the subpopulation.
