Communities living in these muddy areas are very rich in quality as well as quantity and with high interactions between the different species. With their trophic ethology, their biogenic actions, these species modify largely the sediment quality, its compactness for example is r

Common patterns in the fluctuations of macrozoobenthic species living at different places on tidal red over Balgzand (a 50 km. tidal flat area in the westernmost part of the Wadden Sea) and at 5 stations located in a small (3 km.) area 150 km away from Balgzand in the eastern part of the Dutch Wadden Sea. In 25 species, numbers per m. were, in most years, sufficiently high at 2 or more of the Bal

Preliminary observations on , (da Costa, 1778) on the Portuguese coast,productive cycle and the annual changes in the population size-structure, and makes comparisons with similar data from the species’ northern geographical limits. The major latitudinal changes are a longer spawning period extending later in the autumn, smaller maximum sizes and shorter life spans.
