The intertidal fauna of a Belgian sandy beach was sampled on an hourly basis with a hand-pushed sledge to study circadiel patterns in species composition. Four assemblages could be distinguished with classification and ordination techniques. A first division separated the samples taken during daytime from the night samples. Both assemblages were subsequently divided into an ebbtide and a floodtide situation. Light intensity and tidal height were the most important variables explaining the variation in the Canonical Correspondence Analysis. |

Early (post)larval fish constitute a significant part of the temporary hyperbenthos, i.e. of the fauna living in the lower reaches of the water column close to the substratum. Information on the densities and spatial and temporal variations of these stages, as well as on their lengths at the moment of occurrence, can be an important contribution to the knowledge of their dispersion, migrations and to the identification of possible bottlenecks in their recruitment. Therefore the hyperbenthos of the Voordelta, a shallow coastal zone in front of the Dutch Delta, as well as that of the subtidal channels and the intertidal brackish marsh creeks of the Westerschelde Estuary, was sampled monthly during one year by means of a sledge and a stow net. A total of 37... |
