Biodiversity of littoral nematodes from two sites in the Gulf of California

Abstract

The Gulf of California, Mexico, consists of unique environmental conditions resulting in a rich array of biological diversity. Nematodes are present in most marine sediments and are probably the most abundant metazoans. This research analyses and compares nematode biodiversity in two shallow, littoral locations of the Gulf and compares the results with other Pacific and Atlantic faunae. Samples collected in Punta Estrella and Santa Clara were processed for nematode extraction by standard methods. A total of eighty genera were identified, sixty-seven occurring in coarser sediments at Punta Estrella and fifty-five in more silty sediments at Santa Clara. Nematode abundance was higher at the latter location, on average. The region was not especially high or low in diversity compared to other littoral sites, and was most similar to locations in Europe with a corresponding ecology but at temperate latitudes.
