The Presidente Figueiredo region holds a unique biogeographic position at the interface between the Guiana Shield and Amazonian highland ecosystems. This transition zone hosts an exceptional mosaic of habitats, where species from different biomes overlap, interact and respond sensitively to environmental and climatic changes. Studying biodiversity in this region enables Amazon Nexus to capture ecological dynamics that are not observable in lowland forests alone, making Presidente Figueiredo a strategic natural laboratory for understanding patterns of species distribution, resilience and conservation across the Amazon.
