Parameters from the community of leaf-litter frogs from Estação Ecológica Estadual Paraíso, Guapimirim, Rio de Janeiro State, southeastern Brazil

Abstract

We studied the leaf-litter frog community of Estação Ecológica Estadual Paraíso, in Guapimirim, Rio de Janeiro State, southeastern Brazil. Herein we combined three sampling methods (large plots, visual encounter surveys and pit-fall traps) to present data on species composition, richness, relative abundance and densities. The local assemblage of frogs associated to the leaf-litter was composed by 14 species, belonging to nine families. Haddadus binotatus, a direct-developing frog, was the most abundant species in the community. The estimated density of the local leaflitter frog assemblage based on plot sampling was 4.3 frogs/100 m 2 . Haddadus binotatus had the highest density (1.1 ind/100 m 2 ). Frogs were predominantly found at night. Thoropa miliaris had the largest values of SVL (39.0 ± 10.3 mm), whereas the smallest species were Euparkerella brasiliensis (16.7 ± 2.2 mm) and E. cochranae (16.0 ± 2.7 mm). Rhinella ornata had the highest mean body mass (12.1 ± 7.5 g), and E. cochranae the lowest (0.4 ± 0.2 g).

“…Available ecological information on R. ornata is restricted to its reproductive modes (e.g. Pombal Junior and Haddad, 2007), development and body size (Rebouças et al, 2019), ecosystems energy flow (Ohashi and Silva, 2009), activity (Rocha et al, 2011) and adults feeding habits, microhabitat use and daily activity period (e.g. Maia-Carneiro et al, 2013).…”
