摘要: Brazilian legislation only grants the necessary licenses to build hydroelectric plants (previous license, installation and operation licenses) if environmental impact assessment studies are carried out, mitigation compensatory measures taken. The formation of a reservoir causes natural habitat loss significant alteration for wild terrestrial aquatic mammals, in Amazonia have affected ecological feeding reproductive habitats mammals chelonians. Monitoring programs out those reservoirs shown chelonians fitting their behavior repertoire new created by reservoirs. During initial phase implantation reservoir, mammal species taken usual home ranges already occupied areas, phenomenon known as dam’s extended effect. formed an area previously without that body water now has influence on phenological rhythms surrounding vegetation well altering seasonal phases hydrological cycle (flood phase, drying drought, flooding phase) which freshwater turtles’ movements fit with, function food availability appropriate habitats. Programs monitor animal populations can establish guidelines mitigate impacts means proper management procedures conservation sustainable
