Data from: The evolution of between-species reproductive interference capability under different within-species mating regimes

Daisuke Kyogoku & Teiji Sota
Sexual selection sometimes favors male traits that benefit their bearers, but harm their mates. The harmful effects of male traits may also extend to females of other species via heterospecific mating interactions. This could affect the coexistence of closely related species during secondary contact. We examined the evolution of the interspecific interfering capability of a beetle (Callosobruchus chinensis) with a congener (C. maculatus) using C. chinensis males reared under conditions of monogamy and polygamy for...

Data from: Optimal foraging by herbivores maintains polymorphism in defence in a natural plant population

Yasuhiro Sato, Koichi Ito & Hiroshi Kudoh
1. Many species of plants and animals exhibit polymorphism for defensive traits. Adaptive foraging by natural enemies has long been hypothesized to maintain such polymorphism, but this has not been clearly demonstrated in a natural prey or host population. 2. The purpose of this study was to address whether the brassica leaf beetle Phaedon brassicae promotes the maintenance of defence polymorphism in the trichome-producing (hairy) and trichomeless (glabrous) morphs of Arabidopsis halleri subsp. gemmifera. Here,...
