Which index is the best to assess stream health?
(Elsevier Science, 2011-01)
Biotic indices are widely used in monitoring the health status of various ecosystems. The choice of the best index is generally done qualitatively depending on a variety of aspects including cost and time. ROC (Receiver ...
Segment scale typology for colombian andean rivers
(2017-04)
This paper presents a method for establishing segment scale typology for the Andean rivers of Colombia. The method incorporates physical and ecological aspects and combines inferences of structural stability and metabolic ...
Assessing the effects of urbanization on streams in Tierra del FuegoEvaluación de los efectos de la urbanización en los arroyos de Tierra del Fuego
(Asociación Argentina de Ecología, 2017-04)
We set out to understand how urbanization affects streams in Ushuaia, Tierra del Fuego. Paired ttestsand linear regressions were used to compare physico-chemical stream habitat variables (i.e., temperature,turbidity, ...
n situ tests for water quality assessment: a case study in Pampean rivers
(Pergamon-Elsevier Science Ltd., 2002-12)
Two invertebrate species (Hyalella curvispina and Palaemonetes argentinus) and one macrophyte (Egeria densa) from a naturally high nutrient content system (Pampean rivers of La Plata, Argentina) were evaluated for their ...
Benthic Diatom Monitoring and Assessment freshwater Environments Standad Methods and Future Chalanges
(Caister Academic Press, 2016)
Since biofilms integrate the environmental effects of water chemistry, along with the physical and geomorphological characteristics of rivers and lakes, they have been widely applied in biomonitoring. In particular, diatoms ...
Concordance between macroinvertebrate communities and the typological classification of white and clear-water streams in Western Brazilian Amazonia
(Instituto Virtual da Biodiversidade, 2012-06-01)
Neste trabalho, nós investigamos se há correspondência entre comunidade de macroinvertebrados e classificação de igarapés em águas claras e brancas no oeste da Amazônia. Nós trabalhos em duas bacias hidrográficas, Rio Moa ...
Implications of macroinvertebrate taxonomic resolution for freshwater assessments using functional traits: the Paute river basin (Ecuador) case
(2021)
Aim: This study aimed at investigating the taxonomic resolutions (TRs) of benthic
macroinvertebrates for freshwater assessments in the scope of the functional trait
approach (FTA).
Location: Macroinvertebrate samples were ...
