Sensitivity of winter phytoplankton communities from Andean lakes to artificial ultraviolet-B radiation
(Sociedad de Biología de Chile, 2001)
Optical characterization of Argentinean lakes, from deep Andean lakes to shallow Pampean ones
(E Schweizerbartsche Verlags, 2014-06-07)
The purpose of this article is to aboard phytoplankton community as an optically active particulate component of water systems. Mayor concepts of hydrologic optics such as water components and processes that determine the ...
Phytoplankton of the Andean Lakes
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 ...
Solar UVR-induced DNA damage and inhibition of photosynthesis in phytoplankton from Andean lakes of Argentina
(E. Schweizerbart'sche Verlagsbuchhandlung, 2004-10)
During January 1999, studies were carried out in temperate lakes of the Andean region of Argentina (41° S, 71° W) to determine the short-term effects of solar ultraviolet radiation (UVR, 280 – 400 nm) upon natural phytoplankton ...
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 ...
Isolation of UV-B resistant bacteria from two high altitude Andean lakes (4,400 m) with saline and non saline conditions
(Microbiology Research Foundation, 2009-12)
Laguna (L.) Negra and L. Verde are high altitude Andean lakes located at the 4,400 m altitude in the Andean desert (Puna) in the Argentine northwest. Both lakes are exposed to extreme weather conditions but differ in ...
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 ...
