Epibenthic predation in marine soft-bottoms: being small and how to get away with itnts in these trays. Juvenile . survived periods where they are most susceptible to epibenthic predation in the protected burrows of their mother. Extended parental care enables juvenile amphipods to recruit immediately into the adult habitat with a good survival chance. It is hypothesized that some

Abundance, feeding behaviour and nematocysts of scyphopolyps (Cnidaria) and nematocysts in their preyphopolyps. These rhopaloids were earlier included within the euryteles and were not considered to be separate nematocysts. They are distinctive from the euryteles due to the two swellings on their discharged shaft..The absence or presence of the nudibranch . on laminarian thalli possibly has an eff

The importance of intraspecific competition in a , population in the Wadden Sea of small winkles even from cages with 10 to 20 times natural density of large individuals. Of greater importance was the original number of winkles at the site. The available resources on the mussel beds appear to be sufficient to maintain a high population density. Intraspecific competition does n

Parasites on an intertidal ,-bed: factors determining the phenology of microphallid trematodes in thon between snails and amphipods during this period, and (3) a general increase in the . population during late summer. From samples collected between 1990 and 1995 it is shown that microphallid trematodes occasionally may give rise to mass mortality in the amphipod population. The prerequisites for

Within-specimen analyses showed that toxicity was higher in the ectosome than in the choanosome of the sponges. There was a seasonal pattern of change in the toxicity of the species.
