About the Cover
Cover image: Male Astatotilapia burtoni, a cichlid fish endemic to Lake Tanganyika (east Africa) engaged in a boundary dispute through posturing and intimidation. A. burtoni is a highly social fish were males adopt one of two adult phenotypes, territorial and non-territorial. In this photo, two territorial males are fighting over their mutual territorial boundary. This fish has been a valuable model system for understanding the effects of the social environment on behavior, reproduction and the brain. Photo: R. Fernald. Submitted by Julie K. Desjardins and Russell D. Fernald, "How do social dominance and social information influence reproduction and the brain?"
