,Régressions et interpolations,First, it is easy to avoid thinking about sediment movement because it does not occur when one walks out on a sand- or mudflat, and one often avoids it in diving situations as well. Second, very little is known about the mechanics of particle deposition in water, so one cannot extrapolate readily to

This recommendation was made by Ralph Johnson in 1974, but it has scarcely been heeded. He urged benthic ecologists to devise measures of the food resource and its partitioning that were relevant to the requirements and

Models of the feeding and behavior of deposit feeders are a recent addition to benthic ecology (e.g., Calow, 1975; Jumars et al., 1982; Levinton and Lopez, 1977; Taghon et al., 1978; Taghon, 1981). This chapter discusses models that fall under the general heading of optimal foraging theory.

The ability to use such food is indicated by feeding experiments which have shown ingestion selectivity by deposit feeders for protein-coated beads (Taghon 1982; Taghon and Jumars 1984) and demonstrated an ability to absorb non-living organic matter (Lopez et
