Resumen:
The marine areas of South America (SA) include almost
30,000 km of coastline and encompass three different oceanic
domainsthe Caribbean, the Pacific, and the Atlantic
ranging in latitude from 12uN to 55uS. The 10 countries that
border these coasts have different research capabilities and
taxonomic traditions that affect taxonomic knowledge. This
paper analyzes the status of knowledge of marine biodiversity in
five subregions along the Atlantic and Pacific coasts of South
America (SA): the Tropical East Pacific, the Humboldt Current,
the Patagonian Shelf, the Brazilian Shelves, and the Tropical
West Atlantic, and it provides a review of ecosystem threats and
regional marine conservation strategies. South American marine
biodiversity is least well known in the tropical subregions (with
the exception of Costa Rica and Panama). Differences in total
biodiversity were observed between the Atlantic and Pacific
oceans at the same latitude. In the north of the continent, the
Tropical East Pacific is richer in species than the Tropical West
Atlantic, however, when standardized by coastal length, there is
very little difference among them. In the south, the Humboldt
Current system is much richer than the Patagonian Shelf. An
analysis of endemism shows that 75% of the species are reported
within only one of the SA regions, while about 22% of the
species of SA are not reported elsewhere in the world. National
and regional initiatives focusing on new exploration, especially
to unknown areas and ecosystems, as well as collaboration
among countries are fundamental to achieving the goal of
completing inventories of species diversity and distribution.
These inventories will allow accurate interpretation of the
biogeography of its two oceanic coasts and latitudinal trends,
and will also provide relevant information for science based
policies.uN to 55uS. The 10 countries that
