Abstract
Spiders are indicators of environment quality due fact of been sensible to environment changes. Their adaptions among the environment and their relations between vegetal communities make them have a special role in forest ecosystems. However, this relation makes spiders susceptible to effects of urban process and to defloration and ecosystem fragmentation process. A spider fauna survey was developed using 50 “pitfall traps”, annual sample process begun in 2010 and finished in 2011 (total samples = 600) in an urbanized patch. A total of 1238 individuals were collected, constituting 51 species belonged to 18 families which Zodariidae and Lycosidae were most abundant, and Salticidae and Theridiidae were the richest families. It´s also observed many rare species (Singletons and Doubletons). The richness estimators didn´t exhibit a trend do exhibit an asymptote and the relation between collected species and estimated species, suggesting more samples process also suggests a necessity of develop politics to preserve the local biodiversity.
