The microbial mercury link in oligotrophic lakes: Bioaccumulation by picocyanobacteria in natural gradients of dissolved organic matter
(Pergamon-Elsevier Science Ltd, 2019-09)
Andean Patagonian lakes are oligotrophic systems characterized by low dissolved organic carbon (DOC) levels and moderate to high Hg concentration that determine naturally high Hg/DOC ratios and bioavailability. In these ...
Summer Stratification of Andean Lakes of Patagonia and Tierra del Fuego. Global Warming or Enso Effects?Estratificación de verano de los lagos andinos en la Patagonia y Tierra del Fuego: ¿Calentamiento global o efectos del ENOS?
(Universidad de Concepción. Facultad de Arquitectura, Urbanismo y Geografía. Departamento de Geografía, 2010-04)
Lakes are traps of water and sediment. As such, they can record past times climate changes. High-latitude Andean piedmont lakes only give information of the interglacial periods -ice-free periods. Climatic studies should ...
Evolution of ice-dammed proglacial lakes in Última Esperanza, Chile: Implications from the late-glacial R1 eruption of Reclús volcano, Andean Austral Volcanic Zone Evolución de lagos proglaciales embalsados por hielo en Última Esperanza, Chile: Implicanci
(2011)
Newly described outcrops, excavations and sediment cores from the region of Última Esperanza, Magallanes, contain tephra derived from the large late-glacial explosive R1 eruption of the Reclús volcano in the Andean Austral ...
Hydrochemistry, isotope studies and salt formation in saline lakes of arid regions: Extra-Andean Patagonia, Argentina
(Elsevier, 2022-04)
The most favourable locations for the development of saline lakes are in the rain-shadow of mountain ranges, which provide large areas of precipitation catchment while the base of the basin is under arid climate and exposed ...
Effect of glacial lake outburst floods on the light climate in an Andean Patagonian lake: implications for planktonic phototrophs
(Springer, 2018-07)
Climate change is altering temperature and precipitation patterns all over the world. In North Patagonia, glaciers of the Tronador mountain (41°S) show a continuous and maintained recession, and these meltwaters are ...
Physicochemical Parameters Affecting the Distribution and Diversity of the Water Column Microbial Community in the High-Altitude Andean Lake System of La Brava and La Punta
(MDPI, 2020)
Due to the low incidence of precipitation attributed to climate change, many high-altitude Andean lakes (HAALs) and lagoons distributed along the central Andes in South America may soon disappear. This includes La Brava-La ...
Forged under the Sun: Life and Art of Extremophiles from Andean Lakes
(Wiley Blackwell Publishing, Inc, 2016-01)
High-altitude Andean lakes (HAAL) are a treasure chest for microbiological research in South America. Their indigenous microbial communities are exposed to extremely high UV irradiation and to multiple chemical extremes ...
Differential piscivory of the native Percichthys trucha and exotic salmonids upon the native forage fish Galaxias maculatus in Patagonian Andean lakes
(Elsevier Gmbh, 2007-02)
The present paper analyses predation patterns, of Percichthys trucha and salmonid fish upon Galaxias maculatus in five lakes of northern Patagonia with differing community and environmental characteristics. Tank experiments ...
UV-Resistant Actinobacteria from High-Altitude Andean Lakes: Isolation, Characterization and Antagonistic Activities
(Wiley Blackwell Publishing, Inc, 2017-05)
Polyextremophiles are present in a wide variety of extreme environments in which they must overcome various hostile conditions simultaneously such as high UVB radiation, extreme pHs and temperatures, elevated salt and ...
