| Abstract |
|
The role of the endocrine system in regulating the expression of behavior in vertebrates has become the paradigm for studies at both proximate and ultimate levels of analysis. This chapter reviews variation in reptilian reproductive behavior that is induced by different endocrine networks. We focus on the roles of natural and sexual selection to provide the structure for understanding the functional role of the various components of the endocrine system at the proximate level. We specifically review models for the evolution of male–male interactions, ideas underlying the evolution of density regulation (r-K selection) and viviparity, parental care, and recent models for the evolution of sociality. We highlight empirical results that indicate that reptiles, and in particular lizards, display considerable variation in social systems. Notably, we also describe patterns of sociality that include both nuclear family structure in large groups and cooperation (e.g., greenbeard selection), which until recently were thought to be restricted to mammals, birds, and social insects. While details of the endocrine control of endocrine systems related to male behaviors have been quite well studied in reptiles (testosterone (T), arginine vasotocin (AVT), neuroendocrine), we point out other systems that have received little attention (e.g., prolactin (PRL)) and suggest likely control points for the endocrine regulation of alternative reproductive strategies.
