Indigenous territories and protected areas are crucial for ecosystem connectivity in the Amazon basin.

ABSTRACT: Ecosystem connectivity-the uninterrupted flow of natural processes within and among ecosystems-is critical for maintaining healthy ecosystem functions. However, in the Amazon drainage basin, multiple anthropogenic activities are rapidly disrupting connectivity. To assess the severity of this problem, we analyzed the spatial distributions of six major anthropogenic activities: dam construction, deforestation, fire, mining, oil and gas exploitation, and roads. We examined their impacts across four key landscapes: Amazonian Andes, lowland nonflooded forests, wetlands, and rivers. Using a resistance-based connectivity model, we quantified connectivity across terrestrial, wetland, and river ecosystems and found a marked decline in connectivity across the basin. A central focus of our study was
