Abstract
Matrix-habitat and edge effects on amphibian communities in the Brazilian Atlantic rainforest Brazil's Atlantic rainforest has been reduced to 10% of its historical range but still harbors a tremendous amount of endemism and diversity. This is particularly true for amphibians, which are represented by over 300 endemic species. As primary forest is lost and replaced with plantations, the effects of these new matrix types on amphibians are critical to understand. We investigated the effects of the dominant matrix types (coffee plantations, Eucalyptus plantation, and secondary forests) and their edge effects on bromeligenous and leaf litter frogs along a reserve in the mountainous regions of Espírito Santo in southeastern Brazil. Both species diversity and the total abundance of frogs were lower in coffee plantations, Eucalyptus plantations, and secondary forests than in the interior of the reserve. In addition, species diversity in edge habitats was lower than in interior forest for coffee plantations and Eucalyptus plantations matrix types. All bromeliad-dwelling frogs were found only in the forest interior. Results suggest that, in general, 1) species prefer primary forest, 2) matrix habitat types will only be used by some species, and 3) edge effects are greater for matrix types that represent the largest contrast with primary forest. We will discuss the role of the local community in habitat loss and bromeliad collections. We will also discuss our involvement in the local community, including interviews, discussions and education programs.
