Revisión del estado de conocimiento de los decápodos neostrengeria macropa y procambarus clarkii (crustacea: decapoda) en la sabana de Bogotá

Abstract

The present work is a compilation of the existing information on the decapods that inhabit the savannah of Bogotá. Neostrengeria macropa and Procambarus clarkii are two species with very different habits; they are of varied morphology, distribution, reproductive cycle, biology, diet, and occupy a different role in the ecosystem. Neostrengeria macropa is an endemic species of crab that lives at an altitude ranging from 2,200 to 2,900 m above sea level and is a common inhabitant of mountain water bodies, with low temperatures and a large amount of oxygen. Its importance lies in terms of processes of destruction of organic matter and loosening of the soil in the streams. On the other hand, Procambarus clarkii is a crayfish, native to the southeastern United States, but can be found on other continents, where it is often an invasive species. It has been deliberately introduced outside of its area of origin, such as in countries in Asia, Africa, Europe and other parts of the American continent. In Colombia, this species was introduced for the first time in the 1980s in the Valle del Cauca area and its presence was recorded in the Bogotá savannah in 2004. Due to its colonizing potential and constituting a serious threat to the native species, habitats or ecosystems, greater depth and available data are required to make a more conclusive estimate about the impact it may have on the savannah crab due to the fact that this species is classified as an endangered species and its disappearance could generate an ecological problem due to its important role in freshwater ecosystems. The data was collected from the database search, obtaining 126 documents such as books, scientific articles, scientific notes, ndergraduate and postgraduate theses, web pages, management and conservation plans. and non-scientific journalistic publications that include, 65 of Procambarus clarkii, 42 of Neostrengeria macropa, 6 of the savannah of Bogotá and 5 documents of the decapods of the savannah of Bogotá. The results obtained were divided into categories regarding the topics covered in each source of information, inferring that research on the decapods of the Bogotá savanna is still scarce, to establish conservation plans for Neostrengeria macropa and management plans for Procambarus clarkii. However, reviews of the scientific literature allow us to have up-to-date knowledge about the status of the species.
