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 ...
Inorganic mercury (Hg2+) uptake by different plankton fractions of Andean Patagonian lakes (Argentina)
(EDP Sciences, 2013-07)
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 ...
Changes of sub-fossil chironomid assemblages associated with volcanic sediment deposition in an Andean lake (38°S), Chile
(Sociedad de Biología de Chile, 2007)
The susceptibility of cladocerans in North Andean Patagonian lakes to volcanic ashes
1. Explosive volcanic eruptions are one of the few natural phenomena that can produce global catastrophic effects. On 4 June 2011, an eruption in the Puyehue volcanic complex (40°35′S, 72°06′W, Chile) discharged massive ...
Interplay between climate and hydrogeomorphic features and their effect on the seasonal variation of dissolved organic matter in shallow temperate lakes of the Southern Andes (Patagonia, Argentina): a field study based on optical properties
(John Wiley & Sons Inc, 2017-10)
This study analyses the effects of the interplay between climate seasonality and hydrogeomorphic (HGM) lake features on dissolved organic matter (DOM) properties in two neighbouring shallow lakes of Andean Patagonia with ...
Evolution of ice-dammed proglacial lakes in Última Esperanza, Chile: implications from the late-glacial R1 eruption of Reclús volcano, Andean Austral Volcanic Zone
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2011)
Landscape integration of North Patagonian mountain lakes: a first approach using characterization of dissolved organic matter
(Wiley Publishing Asia, 2015-03)
North-western Patagonia contains a variety of glacially formed mountain lakes located at different positions from the treeline in the Andean Patagonian forest region. Water chemistry of six North Patagonian lakes located ...
First characterisation of a CPD-class I photolyase from a UV-resistant extremophile isolated from High-Altitude Andean Lakes
(Royal Society of Chemistry, 2014-05)
UV-resistant Acinetobacter sp. Ver3 isolated from High-Altitude Andean Lakes (HAAL) in Argentinean Puna, one of the highest UV exposed ecosystems on Earth, showed efficient DNA photorepairing ability, coupled to highly ...
