The observed regional differences in juvenile and adult M. arenaria could result from a lack of competent larvae over eastern versus southern Maine tidal flats in the form of either local effects (e.g., postponing metamorphosis to avoid settling on flats characterized by pollution, contamination, or otherwise unattractive habitat qualities until they are carried elsewhere) or regional effects associated with fewer M. arenaria larvae …

For juvenile individuals of M. arenaria and potentially other bivalves, Steamer may be a candidate biomarker for exposure to ocean acidiﬁcation conditions.

Earlier studies demonstrated that densities of 0-y-old individuals of Mya arenaria L. were lower in Washington County on the eastern Maine coast than in Cumberland County on the southern Maine coast. Reduced juvenile recruitment could result from reduced larval abundances, high postsettlement mortality, or a combination of PDF | We present some of the few suspension-feeding measurements and to our knowledge the first velocity-field measurements for early post-settlement | Find, read and cite all the research you influence of sediment acidification on the burrowing behaviour, post-settlement dispersal, and recruitment of juvenile soft-shell clams (mya arenaria l.) by 2017-06-21 in suspension feeding by juvenile Mya arenaria clams Kevin T.

We verify and extend our experimental results with numerical simulations. For 1.8–2.8 mm shell length Mya arenaria clams, pumping rates ranged 0.03–0.22 μl s−1, inhalant siphon Reynolds numbers ( Re) ranged 0.16–0.79 Differences in larval and juvenile uptakeWe found highly significant differences between uptake in larval and juvenile Mya arenaria shells.

In order to indentify factors causing spatial patterns in the bivalve Mya arenaria, abundances of juveniles and adults, as well as death assemblages were recorded on a 20 km scale in the intertidal zone of the Sylt-Rømø bight. Clam landings have dramatically decreased in eastern Maine since 1982. Earlier studies demonstrated that densities of 0-y-old individuals of Mya arenaria L. were lower in Washington County on the eastern Maine coast than in Cumberland County on the southern Maine coast.

Mya arenaria currently occupies a wide geographical range in the northern hemisphere, on both coasts of the Atlantic as well as on the Pacific east coast. Some authors claim it also occurs on the Pacific west coast. The species originated in the Pacific during the Miocene and was already present on both Atlantic coasts in the Pliocene.

35, surface of bench); Richard F. Flint; 1937-08-04 Mya arenaria. Linnaeus, 1758. Soft-shell clams (American English) or sand gaper (British English/Europe), scientific name Mya arenaria, popularly called "steamers", "softshells", "piss clams", " Ipswich clams", or " Essex clams" are a species of edible saltwater clam, a marine bivalve mollusk in the family Myidae . Mya arenaria även kort och gott kallad Sandmussla, även om den benämningen även kan syfta på andra närbesläktade musslor. är en musselart som beskrevs av Carl von Linné 1758. Mya arenaria ingår i släktet Mya och familjen sandmusslor.
