Predizendo impactos sobre espécies de peixes ameaçadas de extinção do Brasil.

Abstract

Species are becoming extinct at extremely high rates. Among the various stressors, we can highlight the destruction of habitats, introduction of exotic species, overexploitation of species, pollution and global climate change. Because of these various stressors, freshwater ecosystems are considered the most threatened in the world, studies that guide or support decision-making are essential to mitigate anthropogenic actions. In order to find patterns at the watershed level, this study sought to predict the effects of different anthropogenic impacts on the distribution of threatened species of freshwater fish. The first study assessed the vulnerability of endangered fish species to climate change. The second studyvdefined priority areas for the conservation of endangered fish species and the third chapter sought to identify the main anthropogenic impacts on endangered fish species in Brazil. Thus, identifying the main anthropogenic impacts at the river basin level is the first for conservation strategies to be adopted.
