High termite richness in an urban fragment of Atlantic Forest in northeastern Brazil

Alta riqueza de térmitas em um fragmento urbano de Floresta Atlântica do Nordeste Brasileiro

Termites are very abundant in tropical ecosystems and have active roles in nutrient cycling and soil formation, but few studies of their assemblages have been undertaken in the Brazilian Atlantic Forest. The present study analyzed the composition of termite assemblages in a fragment of Atlantic Forest embedded within an urban matrix in northeastern Brazil. Five standardized sampling protocols of termites were applied, with a total sampling effort of 1500m². We encountered 45 species of termites belonging to 25 genera and three families. The soil-feeders group demonstrated the greatest species richness, while wood-feeders species were the most abundant. The species richness of termite in the study area was the greatest yet recorded for an Atlantic forest site in Brazil, indicating the importance of urban fragments for conserving tropical biodiversity.
