Abstract: What are the advantages of working with unconventional animal model systems? One distinct benefit is that we can explore natural examples of behavioral plasticity; understanding this plasticity and the mechanisms underlying it has driven much of my research. A central question my lab and I have asked is how the endocrine system influences on behavior and physiology are shaped by the social and physical environments. The importance of context for understanding the meaning of endocrine signals within the body frequently have been ignored. Both the production of testosterone and oxytocin and effects on behavior are highly dependent on both the internal and external environments of individuals. These environments are created by the physical location of the individual, their past mating experiences, and the absence or presence of familiar and unfamiliar conspecifics. I will describe findings from my lab with the monogamous, biparental and territorial California mouse, Peromyscus californicus, that help us to make sense of the many stimuli that a biparental and territorial species needs to integrate in order to adapt to a dynamic environment. Endocrine mechanisms that can influence reinforcement and reward of experiences and alter the salience of social cues can dramatically influence the expression of behavior.
