摘要: Diversity of terrestrial gastropod mollusks in the Pacific region Nicaragua, and their habitat preferences. Landsnail communities Nicaraguan Slope were studied. The study area was subdi- vided into 21 quadrats (ca. 40 x km). A high taxonomic richness found: 79 species, 43 genera 23 families. Species (S) per quadrat ranged from 17 through 50. biogeographic index presented higher values on 5 (3.04), 6 (3.03), 8 (2.96) 11(2.96). Quadrat 11 had highest species (S=50), one (IB=2.96). Gastropod mollusk are favored by sites with an illumination filtered sun, associated to riparian forests a susbtratum wet soils leaf litter. Rev. Biol. Trop. 56 (1): 317-332. Epub 2008 March 31.
