Los moluscos terrestres (Mollusca: Gastropoda) de Costa Rica: clasificación, distribución y conservación

摘要: Terrestrial mollusks (Mollusca: Gastropoda) of Costa Rica: classification, distribution and conservation. are poorly known worldwide. The country has 183 reported species, 30% endemic 7% probably extinct. About 400 species expected to inhabit the country. Biology, ecology, distribution, genetics other areas research unknown for more than 95% species. most diverse families Spiraxidae, Orthalicidae Subulinidae. However, family that may have is Euconulidae. Euconulids highlands, where less work been done. study high- lands will also rise endemism rate. Future taxonomic, biological ecological should consider their low vagility, tendency produce new taxa in sympatry, specific microhabitat requirements, hermaphroditism, high evolutionary rate (10% per million years), divergence between (2 30%). Urgent studies protect Rican malacofauna include: abundance, effect land use climate changes on populations. Rev. Biol. Trop. 58 (4): 1165-1175. Epub 2010 December 01.
