    Notizen: Abstract To evaluate the effects of a deposit-feeding bivalve on meiobenthic assemblage structure in muddy habitats, a laboratory experiment was performed at the Askö Laboratory in the northwestern Baltic proper. Microcosms, surface area 104 cm2, containing a c. 7-cm thick layer of sieved (0.5 mm) sublittoral mud were established in June 1990. Two months later the tellinid bivalve Macoma balthica was added in quantities varying from 0 to 40 individuals per microcosm. After 5 months the effects of the bivalves on the meiofauna were surprisingly small. The density of harpacticoid copepods was lowest (P 〈0.05) in microcosms containing a high density of M. balthica. It is suggested that competition for food resources was responsible for this pattern. For all other meiofaunal groups, including nematodes which were the most abundant taxon (99%), no significant differences (P〉0.05) were observed among treatments. The assemblage structure of the nematodes was similar between treatments. The vertical distribution of both major taxa and nematode species appeared to be unaffected by the presence of the bivalve.

    A new, flow-through corer for the quantitative sampling of surface sediments (1983)

    Notizen: Abstract A new, flow-through benthic corer is described and compared to other commonly used coring methods. The new corer compares favorably with diver coring and is superior to coring with a ball-type, check valve corer, based on recovery of meiofauna, macrofauna, and particle bound hydrocarbons. Check valve corers yielded the most variable results. The new corer may be used to efficiently obtain samples of surface sediments from shallow (〈6 m) water, where a reasonably stable working platform is available.
