Regionalization of the Earth's freshwater biodiversity. The freshwater ecoregion map serves as a complement to the global terrestrial and marine ecoregion maps and differs from them in that freshwater species (primarily fish) and freshwater processes drove the map delineation. Encompasses 426 units, whose boundaries generally - though not always - correspond with those of watersheds. Within individual ecoregions there will be turnover of species, such as when moving up or down a river system, but taken as a whole an ecoregion will typically have a distinct evolutionary history and/or ecological processes. Ecoregions are delineated based on the best available information, but data describing freshwater species and ecological processes are characterized by marked gaps and variation in quality, and improved information in the future may warrant map revisions.
