Male Lekking Duration and Mating Benefits in a Lek-Forming Hawaiian Drosophila

摘要: Variation in lekking duration of males a Hawaiian Drosophila, D. grimshawi, was examined laboratory enclosures. The relationship between variation male activity and number eggs laid by females, proportion hatching, total offspring production investigated. Females mating highly active fewer thus had lower than females less males, even though other studies have shown that grimshawi prefer more as mates. These results are discussed terms conflict over benefits trade-offs faced per mating. Testis mass not related to levels, but with heavier testes produced mating, suggesting may vary ways correlate possible direct fitness gains for females.
