Nematofauna da Praia Formosa, município de Cabedelo - Paraíba - Brasil.

Abstract

Nematoda are represented as one of the most abundant phyla on the planet. They are small in size and can be found in different environments, thus being considered important indicators of soil quality, in addition to habitat stability. The present work had as main objective to characterize qualitatively and quantitatively the nematofauna community, in points with different environmental characteristics in the same tide regime, on a beach located in the municipality of Cabedelo-PB. For the procedure of obtaining the samples, a PVC tube of 4 cm in diameter was used, which was introduced into the sediment up to 10 cm in length, thus removing all samples exactly the same. In the laboratory the nematodes went through the process of diafanization and making permanent slides. Nematodes were represented by 39 genera, with Trileptium, Latronema and Paracanthonchus being the most frequent and most abundant genera of this work. The juveniles, and buccal cavity 2A were considered dominant at the sampling points. Through granulometric analysis, the dominance was of fine sand. Some similarities were found in this study with other beaches on the coast of Paraíba, but it showed less diversity. Thus, the study of another sandy beach on the coast of Paraíba increases knowledge about the local fauna and, consequently, about the Brazilian sandy beaches.
