Flying insects of the night and twilight

How do moths respond to changes in their habitat in human-modified landscapes of the tropics. Dr Joseph Hawes and colleagues conducted one of the first studies (Hawes et al. 2009, Journal of Tropical Ecology) to assess the change in moth diversity in the fragmented landscapes of the Amazon. They found that secondary forests and Eucalyptus plantations can support a substantial level of moth diversity (because of the inherent high structural diversity). But they also show that these forest types hold assemblages with significantly distinct community structures and composition from primary forest indicating impacts of forest degradation on functional diversity. Dr Hawes is now collaborating with BIOFRAG.
