Project summary

This work is carried out at Lago Uauacu in central Amazonia, Brazil (details of the study site can be found in Haugaasen and Peres 2006). The ongoing research focuses on the structural and compositional differences between unflooded and flooded Amazonian forests and their respective contribution to the regional -diversity. The resulting publications have been the first to compare the composition and structure of an entire assemblage of mid- to large-bodied vertebrates in adjacent unflooded (terra firme) and flooded (varzea) forest (Haugaasen and Peres 2005a) with detailed descriptions of the primate (Haugaasen and Peres 2005b) and bird assemblages (Haugaasen and Peres in review a). We have also examined the effects of seasonality on trees and their fruit resources (Haugaasen and Peres 2005c) and in turn the seasonal importance of each forest type for a wide range of resident vertebrates (Haugaasen and Peres in review b).
