The paper tests mating patterns in replicated secondary contact experiments and finds disassortative mating instead of expected assortative mating or reproductive isolation.

This study introduces >12,000 threespine stickleback into nine lakes to test if environmental matching or intrinsic population traits predict introduction success, finding intrinsic traits are more important.

The paper examines flower color variation in Hesperis matronalis along an urban-rural gradient, finding increased diversity in urban areas and systematic shifts in morph frequencies linked to predation and historical fitness differences.

The paper experimentally studies host-parasite dynamics in newly founded stickleback populations, finding destabilized infection rates and rapid eco-evolutionary responses.
