             abstract = "The expansion of hydroelectric dams that is planned, and under 
                         construction, in the Amazon basin is a proposal to generate clean 
                         energy, with the purposes of meeting the regional energy demand, 
                         and the insertion of Brazil into the international economic 
                         market. However, this type of megaproject can change the dynamics 
                         of natural ecosystems. In the present article, the spatiotemporal 
                         patterns of deforestation according to distance from the reservoir 
                         in the vicinity of the lake of Tucuru{\'{\i}}, and within a 
                         radius of 30 km from it, are analyzed. A linear spectral mixture 
                         model of segmented Landsat-thematic mapper (TM), enhanced thematic 
                         mapper plus (ETM+), and operational land imager (OLI) images, and 
                         proximity analysis were used for the mapping of the land-cover 
                         classes in the vicinity of the artificial lake of 
                         Tucuru{\'{\i}}. Likewise, landscape metrics were determined with 
                         the purpose of quantifying the reduction of primary forest, as a 
                         mechanism of loss of ecosystem services in the region. These 
                         methods were also used for the evaluation of the influence of the 
                         distance from the reservoir on the expansion of anthropogenic 
                         activities. This methodology was used for the scenarios of 
                         pre-inauguration, completion of phase I, beginning of construction 
                         phase II, full completion of the Tucuru{\'{\i}} hydroelectric 
                         project, and the current scenario of the region. The results 
                         showed that the highest deforestation rate occurred in the first 
                         period of the analysis, due to the areas submerged by the 
                         reservoir and due to the anthropogenic disturbances, such as 
                         timber extraction, road construction, and the conversion of 
                         forests into large areas of agribusiness.",
