| Data are reported on the amphipods and isopods taken in a sledge-type hyperbenthos sampler in the subtidal of the Voordelta, a shallow coastal area in the Westerschelde, the last estuary of the delta area (SW Netherlands). More than 300 samples were collected between 1988 and 1991. Two salt marches in the brackish part of the estuary were sampled monthly with a flume net in 1990 and 1991.A total of 46 amphipod species (42 gammarideans, 3 caprellids and 1 hyperiid), 19 of which are new for the area were recorded. The dominant amphipod species in the Voordelta and the marine part of the Westerschelde estuary are <i>Atylus swammerdami</i> and <i>Gammarus crinicornis</i>. Estimated densities of both species are high comparison to these... |

| Monthly sampling with a sledge type gear at 24 stations in the shallow coastal area in front of the Dutch Delta (southern bight of the North Sea) shows that high densities of a variety of animals are present in the lower 1 m of the water column: the hyperbenthos. Hyperbenthic community structure is strongly dominated by seasonal fluctuations due to the sequential appearance, high abundance and disappearance of the different species of temporary hyperbenthos. In winter and early spring, when the community is dominated by its permanent residents, spatial patterns emerge. Averaged over the year, these spatial patterns are consistent with the hydrodynamic regime in the system. Sedimentation of silt occurs in the same sheltered areas where the highest biomass... |

| The <i>Pomatoschistus minutus</i> (Pallas) and <i>P. lozanoi</i> (de Buen) stock of the ebb-tidal delta of the former Grevelingen estuary was sampled monthly from September 1992 to October 1993. Sagittae were extracted and the areas of the sagitta and sulcus acusticus were measured with a digitizer. The frequency response and auditory threshold of these two sympatric goby species were determined from the ratio of the sulcus acusticus area to the sagitta area (S:O ratio). The S:O ratio of <i>P. minutus</i> increased while in <i>P. lozanoi</i> the S:O ratio was constant with increasing standard length. The average S:O ratio of <i>P. lozanoi</i> was significantly higher than that of <i>P.... |

| Chapter 1: provides, I believe, a quasi-complete overview of the existing literature on the hyperbenthos. It thus serves as a general introduction to the work presented in this thesis. Studies are situated in space and time and the main structural characteristics of hyperbenthic communities are summarised. Quite some effort is paid to resolve the overriding semantic disagreement which seems to slow down progress in the field. Sampling methodology and the history of hyperbenthic research are reviewed. The role of hyperbenthic animals in marine food webs is briefly touched upon. Chapter 2: describes the hyperbenthic communities of the Voordelta. Twelve locations were sampled monthly at two depths between August 1988 and July 1989.' Three subareas were... |
