Lakes are excellent sponsors of environmental change, including climatic change. Diatoms and ostracods are among the most useful biological indicators for paleoenvironmental reconstruction found in lake sediments, due to their sensitiveness to abiotic variables (Lotter et al., 1999; De Deckker & Forester, 1988). However, the use of these microfosils in quaternary studies for Southern Patagonia is still limited and poorly understood because of the paucity of regional taxonomic and paleoenvironmental knowledge. The multiproxy study of lacustrine sediments from Chaltel presented here aims to partially fill this gap.
