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
(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 ...
Uptake of Hg2+ by picocyanobacteria in natural water from four Andean lakes
(EDP Sciences, 2013-06)
In lake food webs, planktonic bacteria and algae represent the greatest bioconcentration step for Hg2+ and monomethyl-Hg (MeHg). As they are the most abundant organisms in planktonic trophic webs and also the main food ...
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 ...
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 ...
Phytoplankton of the Andean Lakes
(Schweizerbart, 2014-07)
This chapter presents a review of the phytoplankton from the lakes of the Andean Patagonian region. This is one of the most important lake district of Argentina, which encompasses a large number and highly diverse unpolluted ...
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 ...
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 ...
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 ...
