| Streams contain an expressive fraction of the South American fish diversity, mostly composed of small-sized, endemic, and rare species. Populational, reproductive, and diet aspects of Microglanis garavelloi were studied, aiming to make a wide characterization of this species of bumblebee catfish. This is an endemic species of the Upper Paraná River Basin, and the only representative of the genus in the watershed. It is a littoral-dweller of small rivers, with asymptotic length of 34.1 mm and a population mostly composed of individuals with 20-30 mm of standard length. This species presents high fecundity and mortality rate, and low longevity and growth rate. It is a total spawner, October to February being the spawning period, and probably has brood care... |

| ABSTRACT River regulation has fragmented fluvial ecosystems in South America, affecting fish migration and dispersion dynamics. In response, authorities have installed fish passage facilities (FPF) to mitigate impacts. However, little is known about the geographical distribution of these facilities, and no synthesis of the research effort applied to understanding their functioning and limitations exists. To address this issue, our study gathered the available scientific literature about fishways in South America to provide an overview of studied FPF and associated research effort. We found 80 studies that investigated 25 FPF, mostly ladders installed in the upper reaches of large rivers, particularly in the Paraná River Basin. One important finding is that... |

| ABSTRACT The Paranapanema River is a major tributary of the upper Paraná river basin. Eleven hydropower dams regulate its main course, but no study has investigated fish diversity in these impoundments at the basin-scale. The present study investigated spatial patterns of richness, composition, and abundance of native (non-migratory and migratory) and non-native fishes in the cascade of reservoirs along the Paranapanema River. The study is based on data collected from 34 independent studies conducted in nine reservoirs (47 samples). The compilation recorded 161 species, being 111 native (14 migratory) and 50 non-native. Total richness ranged between 56 and 112 species/reservoir, with a mean of 72 (49.9 non-migratory, 8.1 migratory and 14 non-native). The... |
