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. The tellinid Macoma balthica moves extensively about the surface of the sand, its activities not being restricted to vertical movements as hitherto supposed. These horizontal migrations comprise a movement towards the sun followed by a movement away from it. If there is heavy cloud movements still occur, in summer at least, but are at random. MACOMA BALTHICA: A FIELD EXPERIMENT BY E. B. OLAFSSON Department of Animal Ecology, University of Lund, S-223 62 Lund, Sweden SUMMARY (1) Levinton's hypothesis that populations in deposit-feeding communities are more often food-limited than those in filter-feeding communities was field tested using exclusion cages.

This study deals with another aspect: the survival of Macoma in this area. The data used, had been collected from 1969 to 1978 inclusive.
Limited information is currently available on metal ENP effects, uptake, and depuration kinetics in aquatic organisms. In the present study, a deposit-feeding clam, Macoma balthica, was exposed to sediment spiked with Ag and Cu in different forms (aqueous ions, nanoparticles, and micrometer-sized particles) in three experiments.
