Abstract

Diet and microhabitat use by juveniles Rhinella ornata (Anura, Bufonidae) in an insular Brazilian Atlantic Rainforest area.

Highlights

Anuran diet studies in Tropical Forests such as the Brazilian Atlantic Rainforest (BAF) are common for adults, but few analyses include juveniles probably because they are less frequent along the year in comparison to adults (Duellman and Trueb, 1994)
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)
We found a total of seven potential microhabitats that were used by individuals of R. ornata but in different frequencies: Leaf-litter (18%), Tree root (17%), Tree trunk (16%), Trunk (16%), Leaf (16%), Rock (12%) and on Bromeliads (5%)

Summary

Introduction

Anuran diet studies in Tropical Forests such as the Brazilian Atlantic Rainforest (BAF) are common for adults, but few analyses include juveniles probably because they are less frequent along the year in comparison to adults (Duellman and Trueb, 1994). 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). We analyzed the microhabitat use and diet of Rhinella ornata juveniles in an insular BAF habitat.
