Multiscale environmental heterogeneity in a large river-floodplain system
(Pergamon-Elsevier Science Ltd, 2020-06)
River-floodplain systems host very high biodiversity and provide a great variety of ecosystem services due largely to their high environmental heterogeneity, which is strongly dependent on spatial and temporal scales of ...
Quantitative food webs and invertebrate assemblages of a large River: A spatiotemporal approach in floodplain shallow lakes
(Csiro Publishing, 2016-03)
To test the hypothesis that the hydrological regime of large Rivers affects the structure of invertebrate communities and food webs in floodplain lakes, we studied invertebrate assemblages and stomach contents of fish and ...
Turbidity and dissolved organic matter as significant predictors of spatio-temporal dynamics of phosphorus in a large river-floodplain system
(John Wiley & Sons Ltd, 2018-09)
Phosphorus (P) inputs are increasing in river‐floodplain systems, but the factors whichinfluence the dynamics of this nutrient are not clear. To assess P dynamics in this kindof river, the main channel of the Middle Paraná ...
Origin, evolution, and sedimentary records of islands in large anabranching tropical rivers: The case of the Upper Paraná River, Brazil
(2020-06-01)
Anabranching patterns are characteristic of the largest rivers in the world. We have chosen to study the Paraná River because of its worldwide importance among the great rivers and the large database available from over ...
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 ...
Massive tree mortality from flood pulse disturbances in Amazonian floodplain forests: The collateral effects of hydropower production
(2019-04-01)
Large dams built for hydroelectric power generation alter the hydrology of rivers, attenuating the flood pulse downstream of the dam and impacting riparian and floodplain ecosystems. The present work mapped black-water ...
Geoecologia do baixo curso do rio Piancó-Piranhas-Açu
(Universidade Federal do Rio Grande do NorteBrasilUFRNGeografia Bacharelado, 2016-11-10)
Floodplains are ecologically fertile environments due to the high exchange of
sediments and organic matter during and after the flooding of the river and other river
channels and floodplain. The floodplains have ecological ...
Influence of Yacyretá dam on trees distribution in the Paraná floodplain
(Elsevier Science, 2020-07)
Numerous contributions indicate that the distribution of trees in floodplains is determined by hydrological dynamics and that some plants are more tolerant than others to flood periods, however very little scientific ...
Associations between Macrophyte Life Forms and Environmental and Morphometric Factors in a Large Sub-tropical Floodplain
(Frontiers Media S.A., 2018-02)
Macrophyte assemblages are composed of species with different life forms and various ecological functions. Our aim was to investigate the potential environmental determinants of changes in the biomass of individual life ...
