Dams are recognised to impact aquatic biodiversity, but the effects and conclusions diverge
across studies and locations. By using a meta‐analytical approach, we quantified the effects …

Aim We quantify biotic homogenization of fish fauna caused by the elimination of a natural
barrier between two freshwater ecoregions. We also evaluated fish introductions by different …

An annotated checklist for the freshwater fishes from Paraná State, Brazil is provided. A total
of 440 freshwater fish species are recorded for the state, distributed across five ecoregions …

Habitat connectivity is considered a central factor shaping ecological communities, and the
effects of waterway barriers such as natural waterfalls on fish movements are expected to …

Dams change the hydrological dynamics, patterns of biological production and distribution
of organisms in space and time. In contrast, tributary rivers can function as source areas in …

While environmental alterations have made Homo sapiens the hyperkeystone species of the
globe, biotic homogenization initiated a new era, the “Homogenocene.” Still, some terrestrial …

Biodiversity has to be accurately evaluated to assess more precisely possible dam effects on
fish populations, in particular on the most biodiverse rivers such as the Mekong River. To …

Hydrological disconnection is increasingly threatening biodiversity in river floodplain
ecosystems worldwide, but studies reporting long-term change of aquatic biodiversity in …

Water level variation has an important role in the biology of fish species, driving behavior,
feeding, and reproduction both in natural and modified environments. In reservoirs, different …

This work tests the null hypothesis that the coefficients of the total landings, landed values,
mean catches and price per kg of migratory and resident species are constant over time …
