Abstract

Four Cerrado Biome phytophysiognomies (palm tree woodlands, primary semi-deciduous dry forest, secondary semi-deciduous dry forest and Cerrado stricto sensu), at Nazareth Farm (Municipality of José de Freitas, State of Piauí) were sampled using beating tray and pitfall traps. All the collected individuals during the structured protocol and those previously collected in the study area (occasional sampling with pit-fall traps with drift fences) were identified together. A total of 1215 spiders, 40 families and 114 species were sampled. Only 38 species were sampled during the structured inventory. The estimate species richness curves reached from 47 (Bootstrap) to 124 (Chao2) species. The secondary semi-deciduous dry forest harbored the highest spider abundance (n = 221) and species richness (19 spp.). This is the first study to compare these vegetation types, too characteristic in the North of Piauí, and assuredly threatened by the agricultural advance in this state. The spider species richness found at Nazareth Farm is the second higher recorded from Piauí.
