Abstract: | Habituation and its role in the dear enemy effect was investigated in a population of green frogs, Rana clamitans. Green frogs have a prolonged breeding season, and males defend territories centered around suitable oviposition sites. We
tested the prediction that male green frogs will habituate to broadcasts of synthetic conspecific stimuli. Our results indicate
that male green frogs can discriminate familiar from unfamiliar stimuli. We suggest that habituation helps to mediate the
territorial interactions between male green frogs. Strangers present a greater threat than familiar neighbors. By habituating
to the advertisement vocalizations of their near neighbors, males avoid costly interactions with individuals that are not
a major threat to their territories.
