Abstract/OtherAbstract:
|
Arginine vasotocin (AVT) is a neuropeptide that modulates social behavior in amphibians and activates calling in frogs. The Puerto Rican coqui frog, Eleutherodactylus coqui, is a terrestrial anuran that exhibits complex social behaviors, including territoriality and paternal care. Males have a distinctive social hierarchy and can be any of the following: satellite (non-calling), territorial (calling), or paternal (guards and broods embryos). Field experiments were conducted to determine the effects of AVT on satellite behavior and the male social hierarchy of E. coqui. Satellite males were captured within the territory held by a resident male, given injections (i.p.) of AVT or saline (control) and placed back in their original location. To determine if AVT affects all males, not merely satellite males, territorial (calling) males were injected with AVT. Significantly more satellite males commenced advertisement calling following AVT injections than did control males injected with saline. AVT-activated satellites did not challenge the resident territorial male for possession of the territory but instead moved into a new area before commencing to call. In fact, AVT-activated satellite males were significantly more likely to move into a new territory following AVT injections than AVT-injected territorial males. The effect of AVT was short lived, lasting only one night in all but two cases. It is concluded that AVT stimulates advertisement calling and AVT-activated males displayed territorial characteristics of E. coqui. |
