After 5 months the effects of the bivalves on the meiofauna were surprisingly small. The density of harpacticoid copepods was lowest (P <0.05) in microcosms containing a high density of M. balthica. Habitat. Limecola balthica lives a few centimetres below the surface of sand, mud and muddy sand. It is found from the upper regions of the intertidal into the sublittoral, particularly in estuaries and on tidal flats. Description. Mainly mid and lower shore sandy mud or mud in lower estuaries, sheltered bays and marine inlets, often subject to variable salinity.

1997), inducing driving distribution of a dominant infaunal clam, Macoma balthica, along a salinity (i.e., stress) gradient in the York River, Chesapeake Bay, I experimentally examined the effects of predation, recruitment, and food availability in shallow, subtidal, soft-bottom habitats. Specifically, in upriver and downriver zones I quanti- Macoma inquinata, M. nasuta and M. balthica (see descriptions in this guide) are all species with an anterior ventral edge of pallial sinus that is not detached and they tend to be larger (up to 110 mm) than M. acolasta or M. yoldiformis (less than 30 mm).

As an important prey for migratory 78 birds (Piersma and Beukema, 1993), macro-invertebrates (Edjung and Bonsdorff, 1992) L. balthica vit dans la zone septentrionale des océans Atlantique et Pacifique, et son aire naturelle de répartition s'étend jusque dans le subarctique en Amérique du Nord comme en Europe. En Europe, on le trouve de la France au sud jusque dans la mer Blanche et la mer de Pechora, en passant par la mer Baltique.
