Population dynamics of tadpoles ofCrossodactylus gaudichaudii(Anura: Hylodidae) in the Atlantic Rainforest of Ilha Grande, southeastern Brazil

A study on the population dynamics of Crossodactylus gaudichaudii tadpoles in the Atlantic Rainforest of Ilha Grande, Brazil, revealed that tadpoles in early developmental stages (up to stage 25) were present year-round and constituted 80.4% of the sampled population, indicating continuous recruitment into aquatic environments. In contrast, tadpoles in final development stages (stages 42–46) accounted for only 5%, suggesting higher mortality during early development. Tadpole density was significantly linked to rainfall, with higher densities observed during the rainy season compared to the dry season. Body length variations were also noted among developmental stages and seasons. The research, conducted between May 2002 and April 2005 along streams, provides new insights into the population dynamics of this species in the Atlantic Rainforest.
