Levantamento da Mirmecofauna (Hymenoptera, Formicidae) em serapilheira em uma área de restinga da Barra do Rio Mamanguape, Rio Tinto, Paraíba

Abstract

Through studies of faunal survey, it becomes possible to identify species able to provide information on the integrity of the processes taking place in the ecosystem. Some studies indicate that ants can be used as bioindicators of environmental quality. But mirmecofaunísticos studies are lacking in sandbank environments. This study aimed to evaluate the richness and composition of litter ants in sandbank environment of Barra do Rio Mamanguape – PB. Samples were collected in July 2014, the method used was the mini-Winkler extractor. To estimate the species richness of the area, two richness estimators were used: Jacknife 1 and Jacknife 2. Were recorded 50 morphospecies of Formicidae, comprising 22 genera in a total of 5 subfamilies. Species accumulation curves produced by the richness estimators showed that general data of the two estimators was 64spp. The results of this study suggest that more studies should be performed in sandbank environment about the ant fauna that compose it.
