Mountain gorilla life histories, reproductive competition, and sociosexual behavior and some implications for captive husbandry
Abstract 10.1002/zoo.1430090302.abs New data on modal patterns of, and variability in, mountain gorilla life history tactics and sociosexual behavior, collected during long-term fieldwork at the Karisoke Research Centre, are presented here. These data show that immature males and females develop sociosexual relationships with both peers and adults, and that these relationships—which contribute to more complex […]
Differences induced by incubation temperature, versus androgen manipulation, in male leopard geckos (Eublepharis macularius)
A fundamental tenet of sexual selection is that in sexually dimorphic traits, there is variation within a sex. In leopard geckos (Eublepharis macularius), a species with temperature-dependent sex determination, embryonic temperature contributes both to sex determination and polymorphisms within each sex. In this study we report that males from different incubation temperatures, one hitherto untested, […]
