Abstract
Anthropic activities have produced global effects in recent decades accelerating the loss of the ecological integrity in many ecosystems, as well as the risk of extinction of many species. The need to know and preserve endangered species drives us to document the knowledge we have of our biodiversity. The Limnology Section of the Faculty of Sciences of Uruguay has been sampling invertebrates in various limnic environments since its foundation in 1984. The aim of this work was the formation of a malacological collection from these collections. 750 benthic macroinvertebrate samples were reviewed and conditioned according to pre-established protocols. Six families of Gastropoda were recognized: Tateidae, Cochliopidae, Lymnaeidae, Physidae, Ampullariidae and Planorbidae, the latter with the subfamilies Planorbinae and Ancylinae; and six families of Bivalvia: Hyriidae, Solecurtidae, Mycetopodidae, Sphaeriidae, Corbulidae and Cyrenidae. A database was developed linking the material to the limnic system of origin and the publications to which it originated. The results are a malacological collection, with ordered information from more than 30 years of research in limnology.
