M. balthica recruited into all areas of the river but suffered local extinction in hypoxic areas, demonstrating that these areas represent sink habitats. I developed an enzyme-linked immunosorbent assay to quantify fecundity in M. balthica and used it determine the effect of hypoxia on clam fecundity. In laboratory experiments

Macoma balthica habitat

It usually lives in the intertidal or shallow subtidal, and is common in estuaries and bays. [3] 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%.

M. edulis (Newell 1969) and M. balthica (Wilson and Elkaim 1991) sampled from high-shore habitats in summertime. Taken together, the thermal sensitivity of the metabolic rate (do) is expected to decrease towards the warm end of the species distribution range. Lately, invasions (Geller 1999; Wonham 2004) and

However, in British waters Macoma balthica is mainly an intertidal species. Distributed from the White Sea south to Spain and Portugal (Distr. M. balthica). 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.

intertidal habitats. Assessment of sediment temperature profiles from M. balthica habitats has shown that the summer temperature fluctuates from ~ 12 to ~25 °C at Dutch localities (52.9° N), and from ~ 13 to ~29 °C at the species distribution limit (45.6° N), with daily fluctuations in habitat temperature that frequently

They tend to live buried in the sandy or muddy areas of shallow water in the middle and lower Chesapeake Bay. Macoma clams are among the most abundant clams in the Chesapeake Bay. Mature Macoma balthica are rarely over 25 mm long (Dunnill and Ellis 1969), but could be confused with the young of some of these larger clams. Other genera of Tellinidae (ie.

Macoma clams have thin, fragile shells. They have two long, thin, flexible siphons (one of which is longer than the other) that can be pulled completely inside their shells.
