The knowledge of the biological diversity of the spiders of the Amazon is still incipient, it is necessary to expand the research on these animals. Spiders are good objects of study for the evaluation of animal community organization and the influence of habitat on these communities. The aim of the present study was to inventory of the spider community composition in in a pasture used for animal husbandry, in the city of Uruará, state of Pará. The research was developed in the June 2014 by pitfall traps and hand collections. As a result, we collected 99 specimens distributed in six families and 19 morph species. The family with the highest abundance was Araneidae with 63 specimens, followed by Anapidae and Anyphaenidae with 10 specimens each. Through the Chi-square test there was no statistically significant difference between the methodologies of collections (p 0.05), however, both methodologies were supplemented, since the specimens Araneidae sp7, Theridiidae sp1 and Theridiidae sp3 were collected through the pitfall traps, while Araneidae sp5 and Ctenidae sp2 were collected only in hand collections. The Shannon's diversity index showed that even the strongly anthropogenic environment presents a relatively high diversity when compared with other regions more preserved, however, the rarefaction curve of species is not stabilized, showing that should be applied a increase sample effort in future collections.Keywords: Amazon; biodiversity; spiders.
