Long-Term Changes in Planktonic Ciliate Beta Diversity Under Contrasting Hydrological Regulation in A River-Floodplain System. [PDF]

Environ Microbiol
Hydrological regulation by dams reshaped ciliate biodiversity over 14 years, increasing temporal compositional change and ecological uniqueness while accelerating declines in richness and density. These results highlight flood‐pulse dynamics as a fundamental mechanism sustaining biodiversity and ecological integrity in river‐floodplain ecosystems ...

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

International Journal of Biometeorology, 2015
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 ...

Transboundary water relations of the Itaipu Dam

Regions and Cohesion, 2023
Abstract The article identifies an empirical blind spot in the literature on hydro-hegemony, with a scant analysis of power relations and resource control between states in transboundary water relations in a Latin American context. This article aims to fill this gap by examining Brazilian hydro-hegemony in the case of the Brazilian–Paraguayan Itaipu ...
