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 ...
Water and Flamingo Feces Bacterial Communities from High-Altitude Andean Lakes under Selective Antibiotic Pressure Studied by PCR-DGGE Analyses
(IntechOpen, 2015)
High-altitude Andean lakes are exposed to extreme environmental factors like high salinity, ultraviolet radiation, heavy metals, among others. As it was previously shown, these lakes are not only the habitat of a high ...
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 ...
Heavy metal and trace elements in riparian vegetation and macrophytes associated with lacustrine systems in Northern Patagonia Andean Range
(Springer Heidelberg, 2016-09-03)
Vegetation associated with lacustrine systems in Northern Patagonia was studied for heavy metal and trace element contents, regarding their elemental contribution to these aquatic ecosystems. The research focused on native ...
Bacterial community structure in Patagonian Andean lakes above and below timberline: from community composition to community function
(Springer, 2014-10)
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 ...
Reproductive aspects of Galaxias platei (Pisces, Galaxiidae) in a deep lake in North Patagonia
(Csiro Publishing, 2018-05)
Reproductive characteristics of the native fish Galaxias platei were studied in Lake Moreno, an ultra-oligotrophic deep lake in North Patagonia. According to histological analysis of ovaries, G. platei presents synchronous ...
First Report on the Plasmidome From a High-Altitude Lake of the Andean Puna
(Frontiers Media SA, 2020-06)
Mobile genetic elements, including plasmids, drive the evolution of prokaryotic genomes through the horizontal transfer of genes allowing genetic exchange between bacteria. Moreover, plasmids carry accessory genes, which ...
Bacterioplankton composition in tropical high-elevation lakes of the andean plateau
(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 compared the ...
