Primates in a forest fragment in Eastern Amazon

Many new towns were established along the Belém-Brasília Highway following its construction in the 1960s. One was Paragominas, in the northeastern region of the state of Pará (Fig. 1). Large areas of forest in this region were cut for cattle pasture during the 1970s; and due to the depletion of timber resources in southern Brazil, in the 1980s Paragominas also became an important logging center, with the highest concentration of sawmills anywhere in Brazilian Amazonia. Today, timber is scarce in the region, and the sawmills have been moved to new frontiers, although Paragominas still remains an important commercial center for the industry.

Although the remaining fragments suffer from hunting and selective logging, some still maintain primate populations (Lopes and Ferrari, 2000). In this study I evaluate the effects of this land use model on primates in a forest fragment isolated since the late 1970s and composed of three different habitats (unlogged – UN, logged – LG and secondary forest – SF), and compare my results with other studies in the same region.

The potential ecological costs and cobenefits of REDD: a critical review and case study from the Amazon region

Analysis of possible REDD program interventions in a large-scale Amazon landscape indicates that even modest flows of forest carbon funding can provide substantial cobenefits for aquatic ecosystems, but that the functional integrity of the landscape’s myriad small watersheds would be best protected under a more even spatial distribution of forests. Because of its focus on an ecosystem service with global benefits, REDD could access a large pool of global stakeholders willing to pay to maintain carbon in forests, thereby providing a potential cascade of ecosystem services to local stakeholders who would otherwise be unable to afford them.
