The subtidal macrobenthos in the mesohaline part of the Schelde Estuary (Belgium): influenced by man? OMA
Ysebaert, T.J.; De Neve, L.; Meire, P..
The macrobenthos of the subtidal, mesohaline zone of the Schelde Estuary (Belgium) was sampled in October 1996 and 1997 at 54 and 73 sampling locations respectively. Sediments ranged fr om silty to very coarse, with the dominant sediment type being silt (33% of all locations). Of the 35 macrobenthic species observed, only seven species occurred in more than 20% of the samples. The polychaete <i>Heteromastus filiformis</i> and Oligochaeta were most common. Multivariate techniques revealed three distinct communities, linked mainly with sedimentological factors: (1) a species-poor (nine species) community with a dominance of the amphipod <i>Bathyporeia pilosa</i>, a low mean abundance and biomass (86 ind/m², 0.0189 g ash-free dry...

Community structure and intertidal zonation of the macrobenthos on a macrotidal, ultra-dissipative sandy beach: summer-winter comparison OMA
Degraer, S.; Mouton, I.; De Neve, L.; Vincx, M..
Community structure and intertidal zonation of the macrobenthos on a macrotidal, ultra-dissipative beach were studied. On the beach of De Panne, Belgium, six transects perpendicular to the waterline (each with five stations) were sampled in September 1995 (summer) and March 1996 (winter). The 30 stations were distributed across the continuum from mean high water spring to mean low water spring in order to sample the macrobenthos at different levels of elevation. The 39 species found had total densities up to 5,500 ind m<sup>-2</sup> in summer and 1,400 ind m<sup>-2</sup> in winter. The highest densities were found in the spionid polychaetes <i>Scolelepis squamata</i> and <i>Spio filicornis</i>, the nephtyid...
