Abstract
The inland water crustacean communities in southern Chilean Patagonia (46-55 degrees S) are characterized by their marked low species number, and many recurrent species among a wide ecological and geographical gradient, that is due to oligotrophy of lakes and lagoons and the fluvial parameters (i.e., high flow velocities) in rivers. The aim of the present study was to describe the zooplankton communities in lakes and respective outflow river estuaries in Alacalufes National Reserve on islands of Chilean southern Patagonia (49-51 degrees S). Species abundance and presence/absence were considered. The results obtained revealed the presence of a low number of species and also multiple sites in which zooplankton was not recorded at all. This is probably due the low zooplankton diversity of cold lakes at these high latitudes and the often turbulent flow of the outflow rivers studied.
