Lake formation, characteristics, and evolution in retroarc deposystems: A synthesis of the modern Andean orogen and its associated basins
Lake deposystems are commonly associated with retroarc mountain belts in the geological record. These deposystems are poorly characterized in modern retroarcs, placing limits on our ability to interpret environmental signals ...
Differences in bacterial community-level physiological profiles between deep and shallow north-patagonian Andean lakes
(E Schweizerbartsche Verlags, 2018-12)
The utilization of carbon substrates by bacteria results in a process of great ecological significance for aquatic ecosystems. Bacteria are capable of consuming a wide range of organic molecules, but despite the highly ...
Precipitation patterns, dissolved organic matter and changes in the plankton assemblage in Lake Escondido (Patagonia, Argentina)
Global warming affects the hydrological cycle by increasing the frequency and intensity of extreme rainfall events and dry spells. These changes potentially affect the quantity and quality of dissolved organic matter (DOM) ...
Patterns of alluvial deposition in Andean lake consistent with ENSO trigger
The laminated sediment record from Laguna Pallcacocha, Ecuador, is widely used as a sensitive recorder of past variability in the El Nino-Southern Oscillation. However, limited knowledge of local meteorology, ~hydrogeomorphic ...
Bacterioplankton composition in tropical high-elevation lakes of the Andean plateau
(Oxford University Press, 2018)
© FEMS 2018. High-elevation lakes in the tropics are subject to extreme environmental fluctuations and microbes may harbor a unique genomic repertoire, but their composition and diversity are largely unknown. Here, we ...
Fish distribution patterns and habitat availability in lakes Moreno Este and Moreno Oeste, Patagonia, Argentina
(Elsevier Gmbh, 2014-11)
Andean Patagonian lakes are ultraoligotrophic and deep, have simple food webs and low fish diversity and abundance. In this work the distributional abundance data of fish was studied in two interconnected Andean Patagonian ...
Geomorphology context and characterization of dunefields developed by the southern westerlies at drying Colhué Huapi shallow lake, Patagonia Argentina
Patagonia is the only continental territory exposed to the southern westerlies. The speed and frequency of these westerly winds generate a landscape strongly influenced by aeolian processes. This research shows a ...
Changes of sub-fossil chironomid assemblages associated with volcanic sediment deposition in an Andean lake (38°S), Chile
(Sociedad de Biología de Chile, 2007)
