Glaciers retreat, stickleback advance: variation in demographic histories of freshwater stickleback populations

This study examines the demographic history of freshwater stickleback populations in Southern Greenland, finding that lake colonization led to population declines and prolonged gene flow with marine populations, with larger lakes having larger effective population sizes.

Differential phoretic vector use among sympatric Caenorhabditis nematodes and an association with invasive nitidulid beetles in southwestern Germany

The paper investigates vector use among three sympatric Caenorhabditis nematodes in southwestern Germany, finding specific associations with invasive beetles.

Evidence for natural selection shaping the evolution of collective behavior among global Caenorhabditis elegans populations

The paper examines global variation in C. elegans aggregation behavior, finding elevation-driven differences and evidence for natural selection shaping this collective behavior.
