Distribution modelling for Neotropical freshwater stingrays Potamotrygon brachyura and Potamotrygon motoro (Myliobatiformes, Potamotrygonidae) in the Uruguay River basin. [PDF]

J Fish Biol
Abstract This study aimed to identify geographical distribution patterns of the giant short‐tailed river stingray Potamotrygon brachyura and the motoro stingray Potamotrygon motoro in the Uruguay River basin. Data on presence/absence of stingrays were based on fishers' knowledge accessed by interviews through expeditions in Brazil, Argentina and ...

Operations Eclipse Sequencing in Multipurpose Dam Planning

Earth's Future, Volume 11, Issue 4, April 2023., 2023
Abstract A resurgence of dam planning and construction is under way in river basins where untapped hydropower potential could meet growing energy demands. Despite calls for more comprehensive evaluation of dam projects, most dams continue to be planned with traditional methods that neglect interdependencies between planning and management and ...

Evident but context‐dependent mortality of fish passing hydroelectric turbines

Conservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract Globally, policies aiming for conservation of species, free‐flowing rivers, and promotion of hydroelectricity as renewable energy and as a means to decarbonize energy systems generate trade‐offs between protecting freshwater fauna and development of hydropower. Hydroelectric turbines put fish at risk of severe injury during passage. Therefore,

Determinants of population persistence and abundance of terrestrial and arboreal vertebrates stranded in tropical forest land‐bridge islands

Conservation Biology, Volume 35, Issue 3, Page 870-883, June 2021., 2021
Abstract Megadams are among the key modern drivers of habitat and biodiversity loss in emerging economies. The Balbina Hydroelectric Dam of Central Brazilian Amazonia inundated 312,900 ha of primary forests and created approximately 3500 variable‐sized islands that still harbor vertebrate populations after nearly 3 decades after isolation. We estimated
