Diversidad del fitoplancton en el eje fluvial Paraguay-ParanáPhytoplankton biodiversity in Paraguay-Paraná rivers
Phytoplankton biodiversity in Paraguay-Paraná hydrographic basin was analized, including Paraguay and Paraná rivers and its floodplain. This contribution is based upon information published in taxonomic and ecological ...
Distribution of non-native suckermouth armoured catfish Pterygoplichthys ambrosettii in the upper Paraná River basin, Brazil
This study describes the invasion of the upper Paraná River basin by Pterygoplichthys ambrosettii based on a literature review and field samples. Pterygoplichthys ambrosettii has been reported in 42 localities throughout ...
Connectivity processes and riparian vegetation of the upper Paraná River, Brazil
In fluvial systems, the relationship between a dominant variable (e.g. flood pulse) and its dependent ones (e.g. riparian vegetation) is called connectivity. This paper analyzes the connectivity elements and processes ...
Distribución de la vegetación fluvial y su relación con el régimen de pulsos en el Bajo Paraná
(Facultad de Ciencias Naturales e Instituto Miguel Lillo., 2004-12)
The Paraná River has an irregular hydrological regime with regular and extreme floods and at the sites it flows as a typical floodplain river. The pulse regime (frequency, intensity, duration and seasonal variation) is the ...
The geochemical signature of suspended sediments in the Parana River basin: Implications for provenance, weathering and sedimentary recycling
(Elsevier Science, 2016-08)
The Paraná River basin is one of the largest hydrological systems in South America. The present study focuses on the mineralogical and chemical composition of the suspended sediments exported by the Paraná River to the ...
Contrasting the middle Parana and Mississippi rivers to develop a template for restoring large floodpain river ecosystems
(Taylor & Francis, 2007-12)
Effective rehabilitation of large rivers requires a concept of normal floodplain river behavior – the reference condition – to understand systemlevel disturbance history and to develop plans to improve river health. However, ...
FLUVIAL PROCESSES IN ATTACHMENT BARS IN THE UPPER PARANA RIVER, BRAZIL
(Uniao Geomorfologia Brasileira, 2017-07-01)
Bars are semi-submerged fluvial forms associated with the availability of sediments and a temporal dynamic, whose dimensions are controlled by the flow and depth of the channel. Attachment bars are very common in large ...
Genesis and sedimentary record of blind channel and islands of the anabranching river: An evolution model
Blind channel (BC) is a fluvial feature formed by attachment of a lateral sand bar to an island or riverbank. It consists of a 10- to 20-m wide and hundreds to thousands meters long channel, parallel to the island or bank, ...
