The paper investigates a steep hybrid zone between lake and stream stickleback ecotypes, finding that divergent ecological selection maintains reproductive isolation despite recent habitat contact.

This study identifies cis-regulatory changes in the hoxdb gene cluster as the mechanism underlying parallel evolution of dorsal spine reduction in threespine stickleback fish.

The paper presents chromosome-level genome assemblies of Pieris mannii and its sister species, revealing the W chromosome's origin from Z-autosome fusion and its rapid evolution.
