Neuropeptides coordinate complex social behaviors important to both basic and applied science. Understanding such phenomena requires supplementing the powerful tools of behavioral neuroscience with less conventional model species and more rigorous evolutionary analyses. We review studies that use comparative methods to examine the roles of vasopressin and(More)
Despite its well-described role in female affiliation, the influence of oxytocin on male pairbonding is largely unknown. However, recent human studies indicate that this nonapeptide has a potent influence on male behaviors commonly associated with monogamy. Here we investigated the distribution of oxytocin receptors (OTR) throughout the forebrain of the(More)
Arginine vasopressin (AVP) and oxytocin (OT) influence social behavior and cognitive processes and may explain some of the variance associated with individual differences in behavior. Although great focus has been placed on the roles of these peptides in learning and memory, less attention has been given to the receptors to which they bind. The authors(More)
The decision to mate may be one of the most important decisions that animals make. For monogamous species, this decision can carry the added weight of limiting future mating opportunities. The mechanisms that govern these decisions have presumably been shaped by evolution in ways that optimize decision-making processes. In particular, a so-called social(More)
Single males might benefit from knowing the identity of neighbouring males when establishing and defending boundaries. Similarly, males should discriminate between individual females if this leads to more reproductive opportunities. Contextual social cues may alter the value of learning identity. Knowing the identity of competitors that intrude into an(More)
