Hydrologic pulsing promotes spatial connectivity and food web subsidies in a subtropical coastal ecosystem
(Inter-research, 2017-03-13)
Resource pulsing is a widespread phenomenon, but its effects on ecosystem dynamics are often difficult to predict. Hydrological pulsing, in particular, is known to influence the structure and dynamics of fluvial and coastal ...
Morphological variation of freshwater crabs Zilchiopsis collastinensis and Trichodactylus borellianus (Decapoda, Trichodactylidae) among localities from the middle Paraná River basin during different hydrological periods
(Pensoft Publishers, 2014-09)
Measures of hydrologic connectivity have been used extensively to describe spatial connections in riverine landscapes. Hydrologic fluctuations constitute an important macrofactor that regulates other environmental variables ...
Stable isotopes reveal groundwater to river connectivity in a mesoscale subtropical watershed
(2021-01-01)
The Corumbataí River basin (São Paulo, Brazil) has a critical situation regarding water availability due to the intensive use to support agriculture and urbanization, requiring scientific information to face water demand. ...
Discrimination of hydrologic variations for spatial distribution of fish assemblage in a large subtropical temperate river
(John Wiley & Sons Ltd, 2019-10-26)
This study examines the effects of the flow and flood pulses on spatialdispersion of fish assemblages in the floodplain of the Paraná River in Argentina. Wetested the hypothesis that high water levels and greater lateral ...
Hydrological connectivity of alluvial Andean valleys: a groundwater/surface-water interaction case study in Ecuador [Connectivité hydrologique des vallées alluviales andéennes: cas d’étude des interactions eau souterraine/eau de surface en Equateur] [Conectividade hidrológica dos vales andinos aluviais: o estudo de caso da interação das águas subterrâneas/águas superficiais no Equador] [Conectividad hidrológica de los valles aluviales andinos: caso de estudio de interacción del agua subterránea/agua superficial en Ecuador]
(SPRINGER VERLAG, 2016-01-01)
The Andean region is characterized by important intramontane alluvial and glacial valleys; a typical example is the Tarqui alluvial plain, Ecuador. Such valley plains are densely populated and/or very attractive for urban ...
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.) ...
Decomposition of 2D polygons and its effect in hydrological models
(IWA Publishing, 2019)
© IWA Publishing 2019.2D non-uniform polygonal meshes allow representation of the impact of landscape elements and small infrastructures on water flows. The initial vectorial mesh, derived from the intersection of several ...
Spatial variability of chromophoric dissolved organic matter in a large floodplain river: Control factors and relations with phytoplankton during a low water period
(John Wiley & Sons Inc, 2016-04)
Chromophoric dissolved organic matter (CDOM) affects ecological processes in freshwater environments. Few studies assessed its spatial variability and relations with phytoplankton in floodplain rivers. Therefore, these ...
Plankton richness and abundance in several different hydrological situations in lakes lateral to a river: a case study in the mouth zone of a tributary into a tropical reservoir.
(2011-01-01)
A descriptive analysis of the responses of plankton from lakes lateral to a river in its mouth zone into a tropical reservoir to water level variations is presented. Three situations were reported: 1) a comparison of species ...
