M. balthica). Macoma balthica (Linnaeus, 1758) Baltic macoma Native range | All suitable habitat | Point map | Year 2100: This map The habitat may be subject to variable salinity conditions in marine inlets. The species assemblage is characterised by the lugworm [Arenicola marina] and the Baltic tellin [Macoma balthica]. The polychaetes [Scoloplos armiger] and [Pygospio elegans] are typically superabundant and common, respectively. Note: The original Macoma balthica of the Arctic and North Atlantic ocean has been renamed Limecola balthica, according to marinespecies.org. The species previously identified as Macoma balthica in San Francisco Bay has now been recognized as Macoma petalum (which is also found in the North Atlantic American coast), but no morphological differences between the two species have been specified.

In the present paper, the importance of different habitats (intertidal, subtidal and adjacent coastal waters) for the persistence of the population was evaluated for the bivalve Macoma balthica (L.) in the western Dutch Wadden Sea estuary. the movements of a coastal marine bivalve, Macoma balthica, that migrates over several kilometres between the adult habitat on low-lying tidal flats and nurseries for the juveniles at the high flats. Dingle (1996) defined a migration as a ‘persistent and straightened out movement, effected by the animal’s own locomotion or active M. balthica migrates over several kilometres between nurseries at high tidal flats, where juveniles are found in high numbers, and the adult habitat on low-lying tidal flats. bottom-up factors to population abundance of the infaunal clam Macoma balthica in two ecosystems differing in spatial extent by an order of magnitude: the York River, 50 km long, and the Rhode River, 5 km long.

Hoewel dit een mariene soort is verdragen de dieren zeer sterke verlaging van het zoutgehalte ( brakwater ). In de voormalige Zuiderzee leefde de soort nog bij ca. 2‰ totaal zoutgehalte .

In the York, Macoma M. balthica migrates over several kilometres between nurseries at high tidal flats, where juveniles are found in high numbers, and the adult habitat on low-lying tidal flats. Most benthic species in the Wadden Sea have been caught in the water column; also, Macoma balthica has been frequently caught. revealed the Baltic clam Macoma balthica, which according to science normally occur in shallower areas, around 20 15meters depth . The invasive worm Marenzelleria viridis was also found in the mud sample (see Table 2).

In the Pacific Northwest it occurs from northern Alaska to southern California; it is currently listed as a circumboreal species, though Atlantic populations may actually represent a separate species. Habitat: Burrows in soft substrata, particularly in estuaries and on tidal flats, where it may be abundant; intertidal only. Buries shallow to 20 cm under muddy-sandy substrate, commonly in bays and estuaries (Refs. 95344, 95753). In the northern Baltic Sea, known to thrive in eutrophic conditions (Ref. 95752). It is infaunal on sand and eelgrass beds and epifaunal on eelgrass beds (Ref.

The species previously identified as Macoma balthica in San Francisco Bay has now been recognized as Macoma petalum (which is also found in the North Atlantic American coast), but no morphological differences between the two species have been specified. It is thought to have been brought to the Pacific coast by oyster farming. An anoxic layer is usually present within 5cm of the sediment surface and is often visible in worm casts. The habitat may be subject to variable salinity conditions in marine inlets.
