437 Territorial behaviour of the strawberry poison-dart frog, Dendrobates pumilio Heike Pröhl Institut für Zoologie, Tierärztliche Hochschule Hannover, Bünteweg 17, 30559 Hannover, Germany Institut für Zoologie der Universität Wien, Abt. Evolutionsbiologie, Biozentrum, Althanstrasse 14, 1090 Wien, Austria The elaborated social behaviour of dendrobatid frogs has been studied extensively in captivity as well as in the field (Weygoldt, 1987; Zimmermann and Zimmermann, 1988). The ecology and reproductive behaviour of Dendrobates pumilio was investigated by several workers in La Selva, Costa Rica, where some evidence were found on male territorial behaviour (Bunnell, 1973; McVey et al., 1981; Donnelly, 1989a, b). This corresponds to observations in other dendrobatid species where mostly males defend territories (Wells, 1980; Roithmair, 1992, 1994; Summers, 1992; Wijngaarden and Gool, 1994). Dendrobates pumilio inhabits the Atlantic lowland forest in Central America from Nicaragua to Panamd. The species is diurnal, toxic and aposematically coloured. Parental care is complex with role sharing between the sexes: males moisten the terrestrial eggs once a day, females transport the hatched tadpoles to water-filled bromeliads and feed them every few days with unfertilized eggs (Weygoldt, 1980, 1987). In the following pages I will briefly discuss the purpose of territoriality including activity, vocal advertisement,
