Branquiópodos de las masas de agua lacustre del Parque Nacional Cajas (Andes Australes, Ecuador) inventario y notas autoecológicas

Abstract

Extensive sampling of 202 lentic water bodies (lakes, lagoons and ponds) located between 3150 and 4460 m a.s.l. in the Cajas National Park (South Ecuadorian Andes) has revealed the high interest of these mountain enclaves in tropical latitudes for the investigation of faunal and ecological aspects of the branchiopod fauna. The first results allowed to recognize 21 species, 15 of them new to Ecuador, of which 2 are in process of description to be published as new to science. All species are characteristic of little mineralized and oligotrophic waters, 8 of them appear in the plankton and the rest in the limnetic littoral benthos.
