Se confirma la presencia de la raya chupare del Pacífico Styracura pacifica en el Pacífico colombiano. Esta especie junto con S. schmardae en el Atlántico son los únicos representantes de la familia Potamotrygonidae que habitan en aguas marinas y salobres. La distribución confirmada de la especie se limitaba a las costas del Pacífico de Centroamérica, entre el sur de México y Panamá; por tanto, el presente registro extiende su distribución en el Pacífico Oriental Tropical en unos 470 km hacia el sur.
An analysis on the species richness distribution of marine sharks and batoids for the Colombian Caribbean and Pacific regions was carried out. A total of 138 species was documented in nearby marine waters off Colombia, including 76 sharks and 62 batoids; 20 species occurred on both coasts with the Caribbean generally having a higher observed richness than the Pacific. The Caribbean had high richness values both in the insular as well as in the northern region. However, the highest richness values per spatial unit in the Pacific islands of Gorgona and Malpelo, with completeness richness estimate represented mostly by values below 90%. Richness estimators showed values higher than the observed richness, indicating that the inventories and the description of marine shark and batoid richness in Colombia are still incomplete. Despite this, the results of this study are relevant to make decisions aimed at the conservation of this taxonomic group, both in marine protected and unprotected areas of the Pacific and Caribbean coasts of Colombia
The Colombian North Pacific has been a pilot scenario for Marine Spatial Planning (PEM). Over 30 years, it consolidated an inclusive governance model that has allowed the institutional mission to include an ethnic vision of territorial development. In this regard, the declaration of protected areas and complementary conservation strategies have been the pillars that seek to correct conflicts of competition for fishery resources in the industrial and artisanal sectors, the deterioration and over-exploitation of sensitive coastal marine ecosystems, and activities incompatible with a local vocation such as ecotourism. In this complexity, the intersectoral agreements were a de facto result and represented the trust of the actors in a legitimate ordering process and the commitment to guarantee the responsible management of natural resources and the sustainable development of the region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
