On Some Mechanistic Approaches to the Study of Deposit Feeding In Polychaetes

  • Robert B. Whitlatch
Part of the Lecture Notes on Coastal and Estuarine Studies book series (COASTAL, volume 31)


Often, foraging models constructed to predict dietary behavior of organisms partition feeding into a series of choices — decisions about where to forage, which types or quantities of food items to ingest, when to move to a new patch of food, etc. (e.g., Krebs 1978, Stephens and Krebs 1986). The rationale underlying this approach relies heavily on the supposition that as a consequence of evolutionary selection pressure(s), organisms tend to use their food resources efficiently. Given this assumption, it is then possible to develop predictions of how an organism should forage in order to maximize its feeding efficiency and evolutionary fitness.
