Longhorn Beetle (Coleoptera: Cerambycidae) Assemblage and the Structural Heterogeneity of Habitat at the Brazilian Atlantic Forest.

The longhorn beetles play important roles in the forest ecosystem processes and their diversity is affected by many environmental disturbances worldwide. This study aimed at understanding how the structural heterogeneity of the habitat can affect the longhorn beetle assemblage in three areas of an Atlantic Forest, which suffered differential impacts in the past and are now in different successional stages. The area in the most advanced successional stage had mainly lower density of trees, but with greater availability of dead wood, especially larger diameter classes.
