In East and Central Africa, the nymphalid butterflies Danaus chrysippus, Acraea encedon and Acraea encedana are involved in a Müllerian mimicry complex. Unusually for aposematic mimetic organisms, the three species show extensive colour pattern poly

The brown rat, Rattus norvegicus, is a model system in ecological and systematic science, but little is known about its skull morphology and developmental patterns. Our objective was to investigate the cranial ontogenetic patterns in the brown rats,

Female-biased population sex ratios in butterflies arise as a consequence of infection by maternally-transmitted endosymbionts that manipulate host sex ratio in order to maximize their transmission down the generations. A critical step toward underst

Species with extremely female-biased sex ratios are expected to show alteration in the normal sex roles, as a response to male scarcity. The tropical butterfly Acraea encedon is known to be infected with a male-killing bacterium of the genus Wolbachi

Sex ratio distortion in the tropical butterfly Acraea encedana is caused by infection with a male-killing bacterium of the genus Wolbachia. Previous research on this species has reported extreme female bias, high bacterial prevalences, and full sex r

Within the region of East and Central Africa, the aposematic butterfly D. chrysippus is characterized by unusual ecology, due to the co-occurrence of polymorphism, mimicry and sex ratio distortion. In this paper, we describe a survey conducted for D.

Within certain regions in East Africa, the butterfly Danaus chrysippus (L.) shows female-biased population sex ratio, because of the production by some females of all-female broods, as a result of infection by maternally inherited, male-killing bacte
