Habitat and Ecology [top]

Habitat and Ecology:The species is found exclusively in large terrestrial bromeliads (Brocchinia micrantha). Eggs are deposited on the leaves and the exotrophic tadpoles live in the water-retaining leaf axils (phytotelmata). Reproduction does not appear to be seasonally constrained, as courtship and tadpoles have been observed in March and June to August. Females examined in June and July had 1-5 pigmented eggs (0.9-1.1 mm), with clutch size usually comprised of 4 eggs. Tadpoles feed on detritus, insect larvae, unfertilized eggs and other tadpoles (Kok et al., 2006).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The species might be extirpated in the near future in Kaieteur National Park, as its typical habitat is being slowly invaded by the neighbouring forest. Dead leaves from the surrounding trees cause the disappearance of suitable breeding habitat by filling the bromeliad phytotelms. Observations and interviews with local people suggest that this might have happened in the past to several populations of the species within the park (P. Kok, pers. comm. 2008).

Conservation Actions [top]

Conservation Actions: The species occurs within Kaieteur National Park.
