Influence of the stream structure on longitudinal gradients of thermal recovery in regulated rivers, Sauce Grande River (Argentina)Influencia de la estructura del cauce sobre los patrones de recuperación térmica en ríos regulados
(Universidad Nacional del Sur. Departamento de Geografía y Turismo, 2017-06)
Las presas y embalses alteran la temperatura del agua del río a diferentes escalas témporo-espaciales. Los efectos térmicos de las represas son más marcados inmediatamente aguas abajo y pueden persistir a lo largo de varios ...
Secondary production and biomass of Cladocera in marginal lakes after the recovery of their hydrologic connectivity with a tropical river
(2010)
Secondary production and biomass of Cladoceran populations were studied in two marginal lakes whose connections to atropical river were re-established after a prolonged drought period. This study investigates the process ...
Post-Fire effects in wetland environment: Landscape assessment of plant coverage and soil recovery in the Paraná River Delta marshes, Argentina
(Asociation for Fire Ecology, 2012-08)
During 2008, under a region-wide drought, there were a large number of simultaneous fires in the Paraná River Delta region: the most affected vegetation was in marshes dominated by Schoenoplectus californicus (C.A.Mey.) ...
Limnology and water quality in La Plata basin (South America) – Spatial patterns and major stressors
(2021-01-01)
The La Plata Basin (LPB) is a continental river-system, extending across five countries in South America. The study intended to discriminate limnological and water quality macroscale patterns and the determinants. Samplings ...
Groundwater chemical baseline values to assess the Recovery Plan in the Matanza-Riachuelo River basin, Argentina
(Elsevier Science, 2016-01)
The two most exploited aquifers in the Matanza-Riachuelo River basin are being monitored in the framework of the Integrated Environmental Sanitation Plan that implements the Basin Authority, Autoridad de Cuenca Matanza ...
Drought episode modulates the response of river biofilms to Triclosan
(Elsevier Science, 2013-02)
The consequences of global change on rivers include altered flow regime, and entrance of compounds that may be toxic to biota. When water is scarce, a reduced dilution capacity may amplify the effects of chemical pollution. ...
Rotifer abundance, biomass, and secondary production after the recovery of hydrologic connectivity between a river and two marginal lakes (Sao Paulo, Brazil)
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2009)
Rotifera density, biomass, and secondary production on two marginal lakes of Paranapanema River were compared after the recovery of hydrologic connectivity with the river (Sao Paulo State, Brazil). Daily samplings were ...

Rotifera density, biomass, and secondary production on two marginal lakes of Paranapanema River were compared after the recovery of hydrologic connectivity with the river (São Paulo State, Brazil). Daily samplings were ...
Recovery of dense minerals as derivative in the exploitation of the alluvial terraces of the miño river
(Universidad Nacional de Colombia Sede Medellín, 2010)
Times the main objective of this work is to define an industrial protocol to recover dense minerals present in the alluvial quaternary terraces of the Miño River (NW Spain), rich in a fine-grained and high-density material ...
Water and sediment ecotoxicological assessment in a river affected by former mining activities
(2013-12-01)
During most of the 20th century, the Ribeira de Iguape River Basin experienced intense activity related to mining. As consequence, it is estimated that the Ribeira de Iguape River received the discharges of approximately ...
