Abstract

Land use dynamics and synergistic effects of forest conversion and human colonization have been resulting in collapse of the ecosystem services inside both terrestrial and aquatic interfaces. The consequences of this process are fragmented landscapes with species decline and extinction and watershed degradation. The main goal of this project is assess how the landscape structure and land use dynamics affect biodiversity persistence and freshwater conservation in Amazon deforestation frontier at central part of Rondônia. The relationships between landscape metrics obtained from time series Landsat images and both large-bodied vertebrates occupancy and water river chemistry will analyze for understanding the effects of land use dynamics on Amazonian ecosystems services. This study will allow a wide insight for conservation planning by way quantitative remote sensing data and field surveys in a region with the higher rates of deforestation of Amazon. (AU)
