Assessment of water quality in temperate-plain streams (Argentina, South America) using a multiple approachEvaluación de la calidad del agua mediante un enfoque múltiple en arroyos de la llanura templada (Argentina, América del Sur)
(Asociación Argentina de Ecología, 2012-05)
We assessed the water quality in two pampean lotic systems (Argentina), the Juan Blanco and Buñirigo streams, subjected to different land uses (i. e., the UNESCO Biosphere Nature Reserve versus industry and agriculture, ...
Macroinvertebrate trophic responses to nutrient addition in a temperate stream in South America
(E Schweizerbartsche Verlags, 2013-01)
The present continuous anthropogenic pressure has resulted in an enhancement of nutrient inputs into rivers and streams. This situation has worsened, mainly in agricultural areas, causing an accelerated eutrophication. ...
Water exchange processes estimation in a temperate shallow lake based on water stable isotope analysis
(Taylor & Francis Ltd, 2020-08)
The estimation of lake hydrological characteristics such as evaporation/inflow ratios and water residence time becomes necessary for understanding cycling and potential retention of natural and anthropogenic substances ...
