Habitat Macoma balthica tends to prefer very fine sediments (median grain size 200 μm) with high mud contents (> 20%). The maximum relative occurrence (80%!) is reached in sediments with a median grain size of 0-50 μm and a mud content of 50-60%.

Habitat & Range The Baltic macoma lives buried to 20 cm below the surface in sandy or muddy bays and estuaries, from the intertidal to a depth of 40 m. 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. Distributed from the White Sea south to Spain and Portugal (Distr.

(2) Densities of the bivalve, Macoma balthica, were varied experimentally in a sublittoral, exposed, sandy sediment and a sublittoral, sheltered, muddy, sand sediment. Densities varied from 0.25 to 4.0 x natural levels in the muddy, sand sediment and from 0.5 to 4.0 x natural levels in the sand sediment. The growth rates of individually marked

A metapopulation structure containing subpopulations with habitat- and location-specific demographic rates, combined with multiple spawning events and larger sizes than found elsewhere in the world, have permitted a boreal marine bivalve, Macoma balthica, to overcome a physiologically
