Dynamics of Phosphorus in sediments of a naturally acidic lake
(Elsevier, 2013-01)
The mechanisms which controls the fixation and/or release of P in sediment of an extremely acidic lake (pH = 2.0 to 3.0) and its response to the influence of eutrophic urban waste water were investigated. The results, in ...
Optical properties and light penetration in a deep, naturally acidic, iron rich lake: Lago Caviahue (Patagonia, Argentina)
(Elsevier Gmbh, 2013-03)
The optical properties and light climate in the deep and extremely acid Lake Caviahue have been studied in order to better understand its characteristics and the possible influence upon the phytoplankton community. The ...
Iron buffer system in the water column and partitioning in the sediments of the naturally acidic Lake Caviahue, Neuquén, Argentina
(Elsevier Science, 2016-05)
Sedimentary iron partitioning was studied for five sediment strata (16 cm depth) at three sampling sites of the naturally-occurring acidic Lake Caviahue (Patagonia, Argentina). Additionally, water column iron was modeled ...
Acidophilic phytoplankton in Argentina: the case study of Lake Caviahue (Patagonia)
(E Schweizerbartsche Verlags, 2014-07-07)
This article presents a review of the studies carried out over a 10-year period in Lake Caviahue, a natural acidic lake located in Patagonia. The main patterns of the phytoplankton populations are described. Five extremophiles ...
Acidophilic phytoplankton of Lake Caviahue, Patagonia, Argentina
(Schweizerbartsche, 2014-07)
This chapter presents a review of the studies carried out over a 10-year period in Lake Caviahue, a natural acidic lake located in Patagonia. The main patterns of the phytoplankton populations are described. Five extremophiles ...
Utilisation of organic compounds by osmotrophic algae in an acidic lake of Patagonia (Argentina)
(Springer Tokyo, 2014-04)
We investigated whether algal osmotrophy in naturally acidic Lake Caviahue is an important process for acquisition of organic carbon and organic nitrogen. To accomplish this, we quantified algal assimilation of organic ...
May a natural lake behave as an efficient Fenton reactor under dark conditions?
(Springer, 2019-09)
Phenol degradation experiments were performed to study the potential behavior of the acidic Lake Caviahue (LC) as a dark Fenton reactor under natural conditions and upon H2O2 addition at doses typically used for technological ...
Lake Caviahue: an extreme environment as a potential sentinel for nutrient deposition in Patagonia
(Springer, 2018-07)
The objective of this study was to determine if extreme acidic Lake Caviahue could be used as a sentinel of atmospheric deposition hypothesizing that the physiological state of algae will be the indicator parameter. The ...
Dynamics of the dissolved organic matter in a stream-lake system within an extremely acid to neutral pH range: Agrio-Caviahue watershed
(Pergamon-Elsevier Science Ltd, 2020-07)
The Agrio-Caviahue is a natural stream-lake system composed of the Upper Agrio River (UAR) -Lake Caviahue- Lower Agrio River (LAR). The system has a broad pH gradient from extremely acid in the hot spring to almost neutral ...
