| The Belgian Continental Shelf (BCS) is characterized by a set of isolated subtidal sandbank systems, which greatly increase the habitat heterogeneity of the area. The meiobenthos of these sandbanks was investigated during 1997 and 1998. In total, 10 sandbanks have been sampled, belonging to three different geographically isolated systems: the Flemish Banks, the Hinder Banks and the Zeeland Banks. No obvious differences in sedimentological characteristics between the sandbanks were found, but biologically some differences could be detected. The more offshore Hinder Banks had the most diverse meiobenthos, while the Flemish Banks harboured the lowest number of meiobenthic taxa. Seasonal and regional differences in terms of densities are a result of a coupling... |

| In view of their densities, benthic meiofauna are potentially important consumers of primary production. Feeding on diatoms and other microalgae has been documented in a variety of benthic meiotaxa, including many species of the numerically dominant nematodes and harpacticoids. Still, a detailed account of the exact diet of most species, and of the quantitative importance of primary producers in it, is lacking. For nematodes, the presumed nutritive importance of diatoms mostly derives from rather hypothetical links between buccal morphology and food. On the basis of such links, the proportion of nematodes supposedly feeding on the diatoms may amount to as much as 85%, suggesting meiofauna to importantly graze on microalgae. In estuarine and shallow coastal... |

| The intraspecific variation of some nematode species from the Southern Bight of the North Sea is discussed.A redescription (or amplification) is provided for following species: <i>Gonionchus longicaudatus</i> (Ward, 1972), <i>Neochromadora angelica</i> Riemann, 1976, <i>N. munita</i> Lorenzen, 1971, <i>N. paratecta</i> Blome, 1974, <i>Sabatieria celtica</i> Southern, 1914, <i>S. longispinosa</i> Lorenzen, 1972, <i>S. punctata</i> (Kreis, 1924).Following taxonomic changes are proposed: <i>Gonionchus villosus</i> sensu Vincx, 1981 nec Cobb, 1920 is synonymized with <i>G. cumbraensis</i> Benwell, 1981; <i>Neochromadora paramunita</i>... |

| The metazoan meiofauna in the region off Kapp Norvegia, Antarctica (Weddell Sea: 71°S, 12°W), was collected from depths between 211 and 2080m. Total meiofaunal abundance ranged from 815 to 5122 ind. per 10 cm² and total biomass from 126 to 966 µg dwt per 10 cm². Nematodes dominated the samples (range 83 to 97%) followed by harpacticoid copepods, polychaetes and kinorhynchs. A typical skewed length frequency distribution was obtained with most nematodes in the 0.4 to 0.6 mm size-class. The meiofauna communities were primarily influenced by bathymetric depth and food availability (e.g. organic matter and microbiota), which in turn are suggested to be directly related to phytoplankton blooms and associated sedimentation pulses. Standing stock and distribution... |

| The interactions between macrobenthic in- and epifauna of a mid-intertidal <i>Ceriops tagal</i> (Perr.) Rob. stand were studied in order to test the relative importance of epibenthic predation pressure on and resource competition with the macro-endobenthos. The study is the fourth in a series of papers based on exclusion experiments in two different parts of the mangrove system at Gazi Bay in southern Kenya. The permanent and visiting epibenthos were excluded using cages. Densities of the macrobenthic taxa Oligochaeta (families Tubificidae and Enchytraeidae), Amphipoda (genera <i>Grandidierella</i> and <i>Ampelisca</i>), Insecta larvae (family Dolichopodidae), Polychaeta (families Nereidae and Terebellidae),... |

| Nematodes are the most abundant metazoans in marine (littoral, estuarine, coastal and oceanic) sediments, extending from the high-water mark into the deepest oceanic trenches (Nicholas, 1975). All marine free-living nematodes are considered to be members of the meiobenthos; small organisms, mainly metazoans, which are separated from the larger macrobenthos either on a methodological basis (i.e. as all animals passing a 1 mm or a 0.5 mm sieve) or a taxonomic basis (i.e. particular animal groups such as Nematoda, Harpacticoida, Gastrotricha, Kinorhyncha, Tardigrada, Foraminifera etc. which consist exclusively or mainly of small species living in sediments). In most circumstances, nematodes are numerically the dominant group of the meiofauna. In fact, they... |

| 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.... |

| Six new species of the genus <i>Richtersia</i> Steiner, 1916 are described from the Mediterranean Sea: <i>R. bathyalis</i> sp.n., <i>R. spinosa</i> sp.n., <i>R. heipi</i> sp.n., <i>R. mediterranea</i> sp.n., <i>R. staresensis</i> sp.n. and <i>R. coomansi</i> sp.n. Some morphological adaptations of <i>R. bathyalis, R. spinosa</i> and <i>R. heipi</i> are discussed in relation to their small body size. The structure of the stomatal region, labial region and spicules is described in detail and probably holds for the entire genus. |
