Comparative population pangenomes reveal unexpected complexity and fitness effects of structural variants

The paper analyzes structural variants in three North American jay species using pangenome tools and long-read assemblies, revealing rapid genome evolution and population size effects on SV dynamics.

ONeSAMP 3.0: Effective Population Size via SNP Data for One Population Sample

ONeSAMP 3.0 estimates genetic effective population size (Ne) from SNP data of a single population using Approximate Bayesian Computation and local linear regression, showing robustness and accuracy in simulated and empirical data.

Population genomics indicate three different modes of divergence and speciation with gene flow in the green-winged teal duck complex

Down Feather Structure Varies Between High And Low Elevation Male Andean Torrent Ducks (Merganetta armata)

The study compares down and contour feather structures between high- and low-elevation male Andean Torrent Ducks, finding significant differences in down feathers but not contour feathers.
