From: Selection for Male Weapons Boosts Female Fecundity, Eliminating Sexual Conflict in the Bulb Mite

Correlated evolution of female fecundity in response to artificial selection on male weapons of the bulb mite Rhizoglyphus echinopus: lines selected for larger weapons (up lines, in red) evolved higher fecundity than lines selected for smaller weapons (down lines, in blue). This correlated response was significant (ΔAICc = 2.81 between two models that only differed in having selection direction as a fixed effect; see Methods) and occurred despite females lacking fighting legs, and selection only being applied to male fighters.
