“…For example, Bonsdorff & Wenne (1989) found that recruits of Macoma balthica were negatively affected by hydrogen sulfide concentrations, so that juveniles were absent at polluted sites, compared with other sites where size-frequency distributions showed many age classes and a clear dominance of juveniles. High sediment metal concentrations have also been found to influence the settlement and survival of M. balthica (McGreer 1982). Site CH lies in a pollution gradient running along the northern channel of the harbour.…”

“…This is similar to Tellina tenuis, for which fluctuations in total densities result mainly from settlement of juvenile individuals, and size-frequencies are dominated by 1-2-year-olds (Evans & Tallmark 1976;Barnett & Watson 1986). Young individuals are also important for the tellinid bivalve Macoma balthica, with small animals (up to 2 years old) predominating in size-frequency distributions (Nichols & Thompson 1982;McGreer 1983). Peaks in total densities (Fig.…”

The population biology of the wedge shell Macomona liliana (Iredale, 1915) was studied at six sites on intertidal sandflats in Manukau Harbour over 2 years. Differences were found in the densities of bivalves between sites, and at each site large seasonal fluctuations in densities were also observed. Withinsite density fluctuations were mainly the result of changes in the numbers of juveniles (< 5 mm long). Length-frequency distributions were dominated by a single mode associated with new recruits. The only major inter-site difference was the scarcity of large bivalves at one site. Recruitment to the macrobenthos occurred over an extended period (summer to late winter or spring), but with markedly different levels of recruitment in the two successive years. Lengthfrequency plots indicated that growth in the first year was 2-3 mm. The possible involvement of hydrodynamics, inter-and intraspecific interactions, and pollution on recruitment, and the importance of mortality and migration to post-settlement survival are discussed.

“…Several studies have demonstrated negative effects of heavy metals on recruitment in soft sediments (Long et al 1995, Watzin & Roscigno 1997, Olsgard 1999. Metals have been found to influence the distribution of bivalves via effects on recruitment (McGreer 1982, Bryan & Gibbs 1983, to reduce recruiting abundances (Watzin & Roscigno 1997, Olsgard 1999, and also to increase recruiting abundances in some instances, for example gastropods (Watzin & Roscigno 1997). Metals have also been demonstrated to affect established assemblages (as opposed to recolonisation); for example, crustaceans (mainly gammarids and cumaceans) were the fauna most affected in an experiment examining the effects of copper on in situ soft-sediment assemblages (Morrisey et al 1996).…”

Influence of an Antarctic waste dump on recruitment to nearshore marine soft-sediment assemblages

Abandoned waste dumps in Antarctica pose an environmental hazard due to contaminant mobilisation in marine and terrestrial habitats. At Casey Station, east Antarctica, a shoreline waste dump has contaminated adjacent marine sediments with metals, hydrocarbons and organic carbon. This study experimentally assessed a model whereby contamination of marine sediment can lead to changes in recruitment and differences in soft-sediment assemblages. We tested the hypotheses that recruitment would be different at disturbed 'station' locations compared to controls and different in contaminated sediment compared to control sediment. We conducted 2 reciprocal sedimenttransplant field experiments over 2 consecutive years in which defaunated sediments were deployed at disturbed locations and control locations and were recovered after 9 mo (March to November: winter), and also after 12 mo. The majority of fauna recruiting to the experiment were highly motile species with non-pelagic lecithotrophic larvae, such as gammarids, tanaids, isopods and gastropods. There were large differences in recruiting assemblages between all locations and there were significant differences in recruitment between disturbed and control locations. Assemblages in contaminated sediment were significantly different from those in control sediment. Differences in abundances of individual taxa between control and contaminated sediment were complex and difficult to interpret. Assemblages recruiting to the control locations were more variable than those recruiting to disturbed locations. This study provides evidence that contaminants in marine sediments adjacent to the waste dump at Casey Station may be having an environmental impact.

“…Although biological research on estuarine mud flats has been extensive in Europe (e.g., Anderson 1972;Beanland 1940;Chambers and Milne 1975;Lammens 1967) and the east coast of North America (Gilbert 1973;Burke and Mann 1974;Tunni-detailed studies from the Pacific coast. Studies on M. balthica have included research on vertical distribution (Vassallo 1969), stratification within the substrate (Vassallo 197 l ) , general ecology and distribution (Dunnill and Ellis 1969), biomass and production (Nichols 1977), and the effects of pollution (Myren and Pella 1977;McGreer 1979aMcGreer , 1979b.

Growth and reproduction of the bivalve, Macoma balthica (Linnaeus, 1758) was studied for one year (April 1977 – March 1978) on an intertidal mud flat in the Fraser River estuary, British Columbia. The maximum number of individuals (1830/m2) occurred in April, then steadily declined throughout the year. Spawning occurred between mid-June and late July but recruitment was slow and prolonged. Peak spatfall (age 0+ individuals) did not occur until the following March when a maximum density of only 410/m2 for newly settled spat was observed. The oldest animals found were 5+ years of age. Maximum growth took place from April through July. The growth rate measured was one of the highest recorded for any M. balthica population. A direct relationship between high water temperatures, a fast growth rate, and reduced longevity was apparent. A regression of body weight on shell height was used to calculate a condition factor (CF), which reached its highest value during growth and its lowest value immediately after spawning. The mean annual biomass measured was 2.96 g dry weight per square metre.
