| Abstract |
The taxonomic richness of marine Nematoda in Brazilian oceanic islands and similarities among them are analyzed. Results are from surveys conducted in Saint Peter and Saint Paul Archipelago, Rocas Atoll, and Trindade Island. A complete faunal list is presented, containing 9 orders, 39 families, and 143 genera. Chromadoridae and Desmodoridae were the richest families with 21 and 13 genera, respectively. Among the genera recorded, Pseudonchus and Paradraconema had not yet been recorded in Brazilian coastal environments. So far results have pointed out high richness and low similarity in composition among the studied islands. However, further studies are required, especially more systematic samplings, to help understand and to confirm the patterns found. Furthermore, to allow for complete biogeographical studies, locations not yet sampled, e.g. Fernando de Noronha and Abrolhos, should also be studied. |
