The study of sex differences has produced major insights into the organization of animal phenotypes and the regulatory mechanisms generating phenotypic variation from similar …
Research into the lives of animals in their natural environments has revealed a rich tapestry of complex social relationships and previously unsuspected social and mating systems. The …
Colour polymorphic species are model systems for examining the evolutionary processes that generate and maintain discrete phenotypic variation in natural populations. Lizards …
Despite the taxonomic, behavioral, and lifestyle diversity among reptile species, behavioral consistency in reptiles has not been examined to the extent that it has been in fish, birds …

In response to stressful events, most vertebrates rapidly elevate plasma glucocorticoid levels. Corticosterone release stimulates physiological and behavioral responses that can …
Summary 1 Recent reviews demonstrate that genetically determined alternative mating strategies (AMS) are widespread and typically consist of morphs that are recognized by …
The evolutionary processes that result in reliable links between male signals and fighting capacity have received a great deal of attention, but the proximate mechanisms underlying …
Species with alternative phenotypes offer unique opportunities to investigate hormone– behavior relationships. We investigated the relationships between testosterone …
We describe discrete variation in throat color, an important sexual signal, in males of 2 populations of the mesquite lizard (Sceloporus grammicus). At one locality, males exhibit …
