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