| The density distribution of meroplanktonic larvae is compared with the density distribution of adults in the benthos, at five coastal stations in the Southern Bight of the North Sea (<i>Abra alba</i> community). Plankton communities were sampled during one tidal cycle, along a buoy traject or at a fixed point; southern and northern locations, 250 m from each central sampling point, have been investigated too. Benthos samples were taken only at the central points of this traject. Meroplankton consisted of polychaete larvae (9 families) and bivalve and echinoderm larvae. The highest density values of these larvae (6,400 ind.10.25 m<sup>2</sup>) are found on the southern sites of each traject (closest to the coastline). The highest... |

| The composition and dynamics of meio- and macrofauna in a subtidal location at Zoagli (Ligurian Sea, Italy) were followed for an annual cycle (from January 1991 to January 1992). Polychaete recruitment occurred during spring and late summerautumn. The increase in density of predatory nematodes (dominated by <i>Oncholaimellus, Viscosia, Mesacanthion </i>and <i>Chromaspirina</i>) and turbellarians corresponded to the collapse of macrobenthos recruits. Such alteration was probably due to predation by turbellarians and predator-nematodes during and immediately after the macrofaunal larval settlement. Differences in predator pressure were observed between spring and autumn. Conversely, no significant impact was observed on bivalves. The... |
