One hypothesis to explain the phenomenon of high bivalve recruitment after severe winters in coastal North Sea sediments is reduced epibenthic predation. Using predator exclusion experiments, I tested the hypothesis that epibenthic predation on the juvenile bivalves Cerastoderma edule, Macoma balthica and Mya arenaria was lower after a severe winter (1995 to 1996) than after a moderate (1996 to 1997) and a mild (1997 to 1998) winter. In C. edule and M. arenaria there was 2-fold evidence for reduced epibenthic predation after the severe winter: (1) significant predation effects occurred only in exclusion experiments after the 2 milder winters but not after the severe winter; and (2) recruits attained larger sizes in August and October after the severe winter suggesting continuous growth rather than truncation of the size spectrum by predators. In M. balthica, predation effects were also significant only after the milder winters but there was no effect on size. In all 3 bivalve species, recruitment at the experimental sites in the fall was higher after the severe winter than after the 2 milder ones. These results suggest that high bivalve recruitment after severe winters is primarily caused by the post-settlement factor of reduced epibenthic predation on the tidal flats. The strategy to conduct several predator exclusion experiments in both sand and mud in 3 consecutive years with differential winter conditions, and while considering migration activity and size development in juvenile bivalves, proved useful to distinguish between cage artefacts and predation effects.

“…However, field assessments of these relationships are seldom done due to the difficulty in quantifying the abundance of appropriate prey items (Stoner et al, 2001; but see van der Veer & Witte, 1993). Benthic macroinvertebrates are an important food source (Gibson, 1994;de Vlas 1979;Amara et al, 2001) and juvenile flatfish can feed not only on whole prey items but also on regenerating body parts such as bivalve siphon tips and polychaete tails tips, heads and tentacles (Kuipers, 1977;Ansell et al, 1999;van der Veer et al, 2011). Using qualitative information from 0-group plaice diet, combined with macrozoobenthic biomass data from specific surveys in intertidal and subtidal areas of the western Dutch Wadden Sea we conclude that, although subtidal areas present much higher total macrobenthic biomass, the amount that is actually available for 0-group plaice does not differ significantly between areas, which suggests that food per se may not explain the redistribution patterns of 0-group plaice in early summer.…”

“…Studies in the western Dutch Wadden Sea helped to elucidate patterns of habitat use by juvenile plaice (Zijlstra, 1972;Kuipers, 1973Kuipers, , 1975Kuipers, , 1977de Vlas, 1979) and to evaluate plaice population dynamics in relation to variation in habitat quality (van der Veer et al, 1990;Karikiri et al, 1991;van der Veer & Witte 1993;van der Veer et al, 2010). It was established that plaice settlement is mainly restricted to tidal flat areas (Zijlstra et al, 1982;van der Veer & Bergman, 1986) and that 0-group plaice remain in this primary nursery habitat until autumn, before moving to deeper waters offshore as suggested by increasing densities in coastal waters (> 3 m depth) (Zijlstra et al, 1982;van der Veer et al, 1990).…”

“…Previous diet studies in various nursery areas have shown that juvenile plaice can be considered as opportunistic omnivorous benthic feeders (e.g. Edwards & Steele, 1968;Kuipers, 1977;de Vlas, 1979;Poxton et al, 1983;Pihl, 1985;van der Veer & Witte, 1993). Therefore, food availability for 0-group plaice was not based on detailed, time consuming stomach content analysis, but on estimates of potential available benthic prey biomass (c.f.…”

showed that the utilization of the western Wadden Sea has greatly changed, with changing patterns of depth distribution of the 0-group. Settlement of 0-group plaice still occurred in the intertidal, however, shortly thereafter, they moved to deeper waters. Such shift in habitat use did not seem to have affected growth rates. Overall, it seems that the western Wadden Sea can still support young-of-the-year plaice population and in spite of changes in habitat use, the functional importance of the area for this group has not been affected.

Lugworms are important members of the macrobenthos of sheltered intertidal sediments, and this study assessed the abundance and distribution of Abarenicola affinis in Otago, southern New Zealand. Using a faecal cast:lugworm ratio (1.00:1.09) revealed a patchy distribution across inlets, with an overall mean abundance of 11.1 individuals/m 2 (range: 3.8 to 21.3 individuals/m 2 ). Distribution patterns varied among inlets, with lugworms mostly confined to the high intertidal zone, but spread across all intertidal zones in one inlet. The lugworm habitat was characterised by muddy to medium sand (55Á233 mm mean grain size) with low organic matter (B 2%) and chlorophyll a (1Á12 mg/g dry sediment) contents. Depending on the inlet, lugworm abundance was related to sediment parameters, indicating that their distribution across Otago inlets is habitat dependent. The present findings also indicate that factors other than those measured contribute to A. affinis distribution and abundance patterns in this region.
