Long-term Hydrologic Variability in a Large Subtropical Floodplain River: Effects on Commercial Fisheries
(John Wiley & Sons Ltd, 2017-03)
We analysed the effects of decadal and annual hydrologic fluctuations on freshwater fisheries catches in the Middle Paraná River for a period of six decades from the 1930s to the 1980s. The climatic fluctuations in this ...
Influence of hydrology on the fish body condition in a large subtropical floodplain
(Sociedade Brasileira de Ictiologia, 2017-03)
With the objective of finding fluctuations on fish body condition in the Middle Paraná River floodplain in different hydrological scenarios, this attribute was analyzed in several trophic groups of a secondary floodplain ...
Impact of water table fluctuations on the seasonal effectiveness of the pump-and-treat remediation in wet–dry tropical regions
(2020-09-01)
The pump-and-treat (P&T) method is a common remediation approach that is used to mitigate occurrences of hydrocarbon contamination. In a well-studied site that had been contaminated by a large volume of jet fuel, continuous ...
Phytoplankton of the Chaco-Pampean Plain
(E Schweizerbartsche Verlags, 2014-07)
This article summarizes the characteristics of phytoplankton of the Chaco-Pampean Plain between the Pilcomayo River (25º15’S; 57º45’W) and the Lower Salado River (31º39’S; 60º45’W) towards the Paraguay-Paraná system. This ...
Spatial variability of chlorophyll-a and abiotic variables in a river–floodplain system during different hydrological phases
(Springer, 2013-06)
Chlorophyll-a (Chl-a) and abiotic variables were measured in the main channel and floodplain waterbodies of the Middle Paraná River to analyse the system dynamics and to assess their spatial variability during different ...
Limnological changes in two shallow lakes from an urban reserve throughout a complete hydrological cycle: proposals for restoration and management
(Inderscience Enterprises, 2013-10)
We analysed the fluctuations of the limnological variables and phytoplankton structure in two shallow lakes located in an urban ecological reserve from Buenos Aires city (Reserva Costanera Sur) during a complete hydrological ...
Response of Eichhornia crassipes (Pontederiaceae) to water level fluctuations in two lakes with different connectivity in the Paraná River floodplain
(Universidad de Costa Rica, 2007-02)
Floodplain lakes are especially dynamic due to the irregular flow regime of the Paraná River and its location along the geomorphologic gradient between the lakes and the river. The response of Eichhornia crassipes (Mart.) ...
Field data and numerical simulation of btex concentration trends under water table fluctuations: Example of a jet fuel-contaminated site in Brazil
(2017-01-01)
Mass transfer of light non-aqueous phase liquids (LNAPLs) trapped in porous media is a complex phenomenon. Water table fluctuations have been identified as responsible for generating significant variations in the concentration ...
Fluctuations in the monthly discharge of Guyana Shield rivers, related to Pacific and Atlantic climate variability
(Taylor & Francis, 2012-06)
The discharge variability of the main rivers that drain the Guyana Shield is analysed over the last 50 years using cross-wavelet, coherence and composite analysis involving oceanic and atmospheric variables. We highlight ...
Effects of the hydrosedimentological regime on nitrogen transport and speciation in a large subtropical floodplain river
(Taylor & Francis, 2017-11)
Hydrosedimentological conditions of floodplain rivers can affect nutrient delivery processes. This study aimed to evaluate the effects of sedimentological and hydrological regimes on N speciation and transport in the ...
