| dc.description.abstract | Distribution and abundance of meiofauna on a sandy beach in Big Lagoon, California, were studied during a 3-week period in the summer of 1996. Sediment cores were taken to a depth of 10 em at three tidal levels. In addition to quantitative counts of meiofauna, exposure to air, percentage water content, and grain size composition were determined f-or each sample. Results of Spearman rank correlations revealed that median grain size, percentage exposure to air, and sediment saturation were strongly correlated to differences in meiofauna abundance at the mid and low water stations. Mean meiofauna abundance was 779 individuals per 100 cm3 of sand. Nematodes and oligochaetes made up approximately 80% of the mean abundance at the midwater stations. Although polychaetes accounted for approximately 70% of the mean total meiofauna at the low water stations, the most numerically dominant group varied on different sampling days and included polychaetes, gastrotrichs, turbellarians, and nematodes. New distributional records for Northern California include Nematoplana nigrocapitula (Turbellaria, Proseriata), Turbanella mustela (Gastrotricha, Macrodasyida), and Microcerberus abbotti (Isopoda, Microcerberoidea). | |
