![]() ![]() The Torrent Duck (Merganetta armata) is one of the four species of ducks that live in fast flowing rivers, and the only one inhabiting mountain rivers from Venezuela to Argentina. Hydroelectric power production on Torrent Duck populations could be mitigated through the modification of the The hydropower intakes showed no impact onĮither the chemistry of the water or the composition of the macroinvertebrate community. Traffic roads and sections downstream of the hydropower intakes. Torrent Ducks tended to avoid the presence of high vehicular Spatial segregationĪmong individuals suggests the effect of territoriality. These conditions were influenced by the width and shape of the river bed. Torrent Ducks were observed in selected sections of rivers where the presence of rapids, high slopes and high water The number of rapids, gradient, total flow, water velocity, relative position to hydropower intakesĪnd abundance of conspecifics were identified as important attributes in Torrent Duck habitat preferences. Habitat variables were measured to determine the factors that influence Indices of Torrent Duck abundance and reproduction were recorded at 74 sampling points distributed alongģ5.4 km of river between 20. ![]() Part of a long-term study, two rivers important for hydroelectric production were surveyed in Central Chile. The Torrent Duck (Merganetta armata) inhabits the torrential rivers of the Andean mountains. ![]()
