Diversity and Habitat Use of Neotropical Harvestmen (Arachnida: Opiliones) in a Costa Rican Rainforest

Table 1

Relative abundance of all species collected from log (L), litter (R), tree (T), and foliage (F) microhabitats in three adjacent forests during diurnal and nocturnal sampling. Abundance of species for diurnal samples are combined across all forest ages and reported only by microhabitat, whereas nocturnal samples show abundance by microhabitat within each forest age.
