Aquatic macrophytes in the large, sub-tropical Itaipu Reservoir, Brazil

open access: yesRevista de Biología Tropical, 2010
In the last three decades, rapid assessment surveys have become an important approach for measuring aquatic ecosystem biodiversity. These methods can be used to detect anthropogenic impacts and recognize local or global species extinctions.

Soybean yield in relation to distance from the Itaipu reservoir. [PDF]

open access: yesInt J Biometeorol, 2016
Crops close to small water bodies may exhibit changes in yield if the water mass causes significant changes in the microclimate of areas near the reservoir shoreline. The scientific literature describes this effect as occurring gradually, with higher intensity in the sites near the shoreline and decreasing intensity with distance from the reservoir ...

Spatiotemporal dynamics of larvae and juveniles of two species of interest for fisheries in Itaipu: A big neotropical reservoir

open access: yesBoletim do Instituto de Pesca
The corvina (Plagioscion squamosissimus) and the mapará (Hypophthalmus oremaculatus) are two of the most explored fish species in the Itaipu reservoir region. However, information on the ecology and dynamics of their initial advances remains scarce.

Spectral Reflectance in the Spatial-temporal Dynamic of Turbidity, Itaipu Reservoir, Brazil [PDF]

open access: yesAnuário do Instituto de Geociências, 2021
Water quality and the useful life of reservoirs and dams are influenced by the entry of suspended solids, in addition to reducing theirtransparency and storage capacity. It is primary to monitor and analyses its space-time dynamics. Thus, the objective of this work isto characterize the dynamics of the Itaipu Reservoir waters from turbidity, rainfall ...

Quantification of metals in macrophytes in an aquaculture area of the itaipu binational reservoir

open access: yesScientia Agraria Paranaensis, 2021
The macrophytes in natural conditions perform an important role in the maintenance and balance of aquatic environments with a capacity of absorbing the excess of nutrients and pollutants serving as bioindicators of water quality in aquatic ecosystems. The objective was to evaluate the levels of trace metals in three species of macrophytes (Egeria densa
