List of freshwater ecoregions of Latin America and the Caribbean
Encyclopedia
This is a list of freshwater ecoregions in Latin America and the Caribbean, as identified by the World Wildlife Fund (WWF).
The WWF divides the Earth's land surface into ecoregion
s, defined as "large area[s] of land or water containing a distinct assemblage of natural communities and species". Ecoregions are grouped into complexes and bioregions, defined as, "a complex of ecoregions that share a similar biogeographic history, and thus often have strong affinities at higher taxonomic levels (e.g. genera, families)." The Earth's land surface is divided into eight ecozone
s. Latin America corresponds, roughly, to the Neotropic ecozone, although northern Mexico lies within of the Nearctic
.
Each ecoregion is also classified into major habitat types, or biome
s.
Many consider this classification to be quite decisive, and some propose these as stable borders for bioregional democracy initiatives.
