(Corophium vol utator, Macoma balthica, Nereis diversicolor)
Acute toxicity of hexavalent chromium to 3 estuarine ammals (Corophium volutator, Macoma balthica, Nereis diversicolor) has been studied at 3 temperatures (5, 10, 15 'C) and a range of salinities (5 to 40 %o, in 5 %O increments), at time intervals of up to 384 h. Toxicity increased as temperature increased and as salinity decreased. From an analysis of variance, the significant factors and thei...
متن کاملActive pelagic migrations of the bivalve Macoma balthica are dangerous
The bivalve Macoma balthica migrates twice during the benthic part of its life cycle. During the spring migration (May–June), the newly settled spat (0-group) migrates to the nurseries in the high intertidal. Seven to nine months later, the bivalves migrate back to the low tidal flats and the subtidal (winter migration, 1-group). Both 0and 1-group M. balthica use byssus threads for active pelag...
متن کاملClimate-related changes in recruitment of the bivalve Macoma balthica
Population dynamics of common intertidal bivalves (Cerastoderma edule, Macoma balthica, Mya arenaria, Mytilus edulis) are strongly related to seawater temperatures. In northwestern European estuaries, series of mild winters followed by low bivalve recruit densities lead to small adult stocks. In this study, we examine temperature-induced effects on reproductive output (eggs m22), onset of spawn...
متن کاملHistopathologic and histochemical biomarker responses of Baltic clam, Macoma balthica, to contaminated Sydney Harbour sediment, Nova Scotia, Canada.
Sediments in Sydney Harbour, Nova Scotia, are highly contaminated by polynuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and heavy metals. Histopathologic and histochemical evaluations were made on the Baltic clam, Macoma balthica, exposed to 11 Sydney Harbour sediment samples. Histologic lesions in digestive gland (tubular dilation or atrophy, macrophage aggregates, tub...
متن کاملEffects of temporary food limitation on development and mortality of Macoma balthica larvae
Long-term observations (1973 to 2001) of populations of the intertidal bivalve Macoma balthica, in the western Wadden Sea, have suggested that larval mortality is strongly densitydependent. In addition, density-independent factors may affect larval mortality. One possible source for such an effect is food limitation. In laboratory experiments, M. balthica larvae were reared under food limiting ...
