Fish invasions in the world's river systems: when natural processes are blurred by human activities.
TL;DR: It is shown that the biogeography of fish invasions matches the geography of human impact at the global scale, which means that natural processes are blurred by human activities in drivingFish invasions in the world's river systems.
Journal ArticleDOI
Partitioning global patterns of freshwater fish beta diversity reveals contrasting signatures of past climate changes
Fabien Leprieur,Fabien Leprieur,Pablo A. Tedesco,Bernard Hugueny,Olivier Beauchard,Hans H. Dürr,Sébastien Brosse,Thierry Oberdorff +7 more
TL;DR: It is found that spatial turnover and nestedness differ geographically in their contribution to freshwater fish beta diversity, a pattern that results from contrasting influences of Quaternary climate changes.
Journal ArticleDOI
Homogenization patterns of the world’s freshwater fish faunas
TL;DR: It is demonstrated that current homogenization of the freshwater fish faunas is still low at the world scale but reaches substantial levels in some highly invaded river basins from the Nearctic and Palearctic realms, stressing the need for further understanding of the ecological consequences of homogenized species assemblages.
Journal ArticleDOI
The use of multiple biological traits in marine community ecology and its potential in ecological indicator development
TL;DR: It is suggested that greater focus on life history ecology and on the links between marine species traits and ecosystem functioning are still needed to support trait-based indicator development.
Journal ArticleDOI

TL;DR: This database results from an extensive survey of native and non-native freshwater fish species distribution based on 1436 published papers, books, grey literature and web-based sources and represents a highly valuable source of information for further studies on freshwater macroecology, macroevolution, biogeography and conservation.
