Restabelecimento da comunidade de rola-bostas (Coleoptera, Scarabaeinae) em diferentes reflorestamentos na região amazônica

Abstract

Habitat loss is one of the major causes of species and ecosystem service loss, resulting in various economic and ecological damages. The adoption of reforestation programs acts as a means to mitigate the impacts generated on the environment, potentially recovering some of the lost biodiversity and ecosystem services. Monitoring the return of typical forest fauna during the reforestation succession process is an efficient methodology to evaluate the success of environmental recovery, considering that they are good indicators of environmental quality, such as dung beetles. In this study, we evaluated how different reforestation models act in reestablishing the dung beetle community in the Amazon region. We sampled the dung beetle community in five environments with different vegetation structures: native forest, mixed reforestation of native species, fig reforestation, teak reforestation, and pasture. We compared temporal changes in richness, abundance, and species composition of the three reforestation models with forest areas, in order to evaluate their success in recovering the native diversity of dung beetles throughout the forest succession process. Overall, changes in dung beetle communities suggest that mixed native species reforestations are the most efficient in restoring biodiversity, but fig tree plantations also have potential for recovery, even if they promote the reestablishment of species at more advanced ages. Teak reforestation presented low potential for management strategies aiming at to recover biodiversity in degraded environments.
