Abstract

The endangered Panamanian golden frog, Atelopus zeteki, is a stream dweller of middle elevation rain forests of the Panamanian isthmus. In order to better understand this species for conservation, we set out to determine the nocturnal whereabouts of this diurnally active animal. It was expected that adult males and juveniles might occupy different nocturnal microhabitats based on differences in size, coloration and patterning. Findings presented here demonstrate that adult males climb significantly higher than juveniles at night and that movement distances to final resting positions also significantly differed. This change in diurnal and nocturnal position in adult males may be related to predator vigilance and avoidance. Lastly, this study demonstrated that individual rain forest amphibians can be successfully tracked over short to moderate distances in humid to wet environments using fluorescent pigments. © 2007 Departamento de Ciências Biológicas.
