TL;DR: The present ostracod diversity results from 9 to 12 separate invasions of the non-marine habitat, starting about 400 Myr ago, which means that all the biological mechanisms which lead up to efficient dispersal have not induced common cosmopolitan distributions in ostracods.

TL;DR: It is demonstrated that urban communities generally consist of smaller species, and that the general trend towards smaller-sized species is overruled by filtering for larger species when there is positive covariation between size and dispersal, which can mitigate the low connectivity of ecological resources in urban settings.

TL;DR: While the ecological role of ponds is now well-established, authoritative research-based advice remains needed to inform future direction in the conservation of small water bodies and to further bridge the gap between science and practice.

TL;DR: Using the most comprehensive fish occurrence database, results suggest that the main center of fish diversity was located westward, with fish dispersal progressing eastward after the basins were united and the Amazon River assumed its modern course toward the Atlantic.

TL;DR: This database, including 2,406 validated freshwater native fish species, 232,936 georeferenced records, results from an extensive survey of species distribution including 590 different sources, represents a highly valuable source of information for further studies on freshwater fish biodiversity, biogeography and conservation.
