Variation in abundances of intertidal populations: consequences of extremities of environment,iation at lower levels, supporting the hypothesis. ., however, showed the opposite pattern, contradicting the hypothesis. Despite close associations between . and ., patterns of relationship of spatial variances were inconsistent. The study demonstrates the need for tests in numerous sites and that

The influence of , abundance on resuspension,ting that indirect effects of . grazing may become more important at high levels of bottom shear stress. The implications of our findings for suspended solids concentration in estuarine systems are discussed.

Preying at the edge of the sea: the nemertine , and its amphipod prey on high intertidal sandflats,axima of . and . usually did not coincide spatially. It is assumed that the nemertines avoid tidal flats that dry out quickly leaving too little time for prey capture. . is not able to dig into the sediment, but lives in burrows of . The abundance of this polychaete was inversely related to ., prese

Spatial and temporal distribution of , (Ophichthidae) and associated fish fauna in a northern Brazitly in time and space. The densities and biomass for the three most dominant species (. spp. and .) differed significantly among species. Only the biomass of these species showed significant monthly differences. The only significant main effect on variance in the densities and biomass of . were enco

,Faecal pellet production by Arctic under-ice amphipods — transfer of organic matter through the icee sea ice (mean: 36.4 mg C m.) and mean amphipod abundances (.: 33.8 ind. m., . spp.: 0.5 ind. m., . 9.4 ind. m.) in the Greenland Sea in summer 1994, the amount of POC transferred from the ice to the water by faecal pellet production was estimated (0.7 mg C m. d. or almost 2% of ice-bound carbon).

Barnacle populations were monitored in summer 199
