This study shows that a male-expressed mating plug in nematodes increases female fertility by extending reproductive windows and reducing sperm loss, indicating reproductive cooperation rather than male competition.

The paper surveys Argonaute genes across 51 Caenorhabditis species, identifying gene gains, losses, and functional diversification, revealing dynamic evolution of small RNA pathways.

This study uses experimental evolution in C. elegans to show sex-specific gene expression changes driven by sexual selection, revealing transcriptomic sexual conflict over short evolutionary timescales.

This paper introduces an auxin-mediated sterility induction system in C. elegans that allows reversible control of fertility, offering advantages over existing methods for studying mating systems and aging.
