Polymorphic Foraging Behavior Among Caenorhabditis elegans: Frequency- and Density-Dependent Selection.

Abstract

Strains of Caenorhabditis elegans obtained from their natural soil environment exhibit one of two forms of foraging behavior. Some strains forage solitarily and disperse evenly on a bacterial lawn. Other strains move rapidly until they encounter groups of conspecifics, and then slow their movement and join the group. Strains expressing these behaviors are… (More)
