Isolation of Bacteria from Remote High Altitude Andean Lakes Able to Grow in the Presence of Antibiotics
(Bentham Science Publishers, 2009-01)
High altitude Andean lakes are placed in Puna desert over 4400 above sea level. Completely isolated, they are exposed to extreme environmental factors like high levels of salinity, UV radiation and heavy metals and low ...
Limnology in El Dorado: some surprising aspects of the regulation of phytoplankton productive capacity in a high-altitude Andean lake (Laguna de Guatavita, Colombia)Limnology in El Dorado: some surprising aspects of the regulation of phytoplankton productive capacity in a high-altitude Andean lake (Laguna de Guatavita, Colombia)
Phytoplankton from natural water bodies of the Patagonian Plateau
(E Schweizerbartsche Verlags, 2014-06)
The Patagonian Plateau is one of the most arid regions of Argentina, where mean annual rainfall ranges between 100 and 200 mm. This region contains different types of water bodies: large artificial lakes, permanent natural ...
Bacterial community structure in Patagonian Andean lakes above and below timberline: from community composition to community function
Lakes located above the timberline are remote systems with a number of extreme environmental conditions, becoming physically harsh ecosystems, and sensors of global change. We analyze bacterial community composition and ...
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
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 ...
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 ...
Inorganic mercury (Hg2+) uptake by different plankton fractions of Andean Patagonian lakes (Argentina).
(EDP Sciences, 2014-07-22)
The species composition and the size structure of natural planktonic food webs may provide essential information to understand the fate of mercury and, in particular, the bioaccumulation pattern of Hg2+ in the water column ...
