Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil. [PDF]

J Fish Biol
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing. [PDF]

Zoo Biol
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

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 ...

For your eyes too: a new set of images of biological materials from the scientific commissioning of the MOGNO beamline at Sirius. [PDF]

J Synchrotron Radiat
From whole specimens to histological level reconstructions, images derived from 3D synchrotron‐based microtomography (SR‐microCT) have emerged as a tool that is revolutionizing a wide range of biological research. This paper presents the first commissioning results from experiments to image the anatomy of small animals and specimens from zooarchaeology

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 ...
