ABSTRACT
The Patagonian lakes are of glacial origin and some of these are associated with glaciers that generate
specific optical properties such as water colorations due to glacier sediments. These lakes also are oligotrophic
with a low crustacean zooplankton species number. The aim of the present study was to analyze
potential associations between optical properties and zooplankton communities in Tagua Tagua Lake (41°S).
The results revealed inverse associations in reflectance of bands 3 and 7 of LANDSAT TM+ with Daphnia
ambigua, Mesocyclops araucanus, and nauplius, and direct Neobosmina chilensis and Cyclopoids copepodites,
whereas it was inverse relations between bands 5 and 2 with B. gracilipes and calanoid copepodites
that make this zooplankton assemblage similar to Nord Patagonian oligomesotrophic lakes. These results
would agree with few reports for other similar Patagonian lakes of glacial origin reported for Argentinean
and Chilean Patagonia. Nevertheless, it is necessary for more studies to find potential associations between
limnological characters and optical properties.
