Behavior and communication
Atelopus zeteki uses thermoregulation to reduce chances of infection with chytrid fungus (Richards-Zawacki 2009). Adults were able to modify their behavior to elevate their body temperatures above normal and above levels generally tolerated by the fungus (Richards-Zawacki 2009). As in many species of Atelopus, A. zeteki does not have a middle ear. However, they do respond to playbacks of calls, which suggests that are able to hear (Lindquist and Hetherington 1996). Lindquist et al (1998) found that the body wall/lungs may serve as a route of sound transfer in these frogs. Male Panamanian Golden frogs wave their hands and feet at other males. These actions, combined with calling, are signals of aggression and territorial defense. The significance of hand and foot waving, along with calling, as a multimodal signal has been studied in detail by Criswell (2008). Lindquist et al (2007) explored the nocturnal movements of juveniles and adults by tracking them with flourescent dye. They found that adults move more and to higher resting spots than juveniles.
