Abstract
A minimal conceptual model has been built that is capable of explaining the microscale heterogeneity observed in the benthic trophic system of harpacticoid copepods grazing on diatom microalgae. Alternative models of trophotaxis in predator-prey systems are considered in which the stimulus for predator movement is prey density, attractant secreted by the prey, or predator satiation. The model in which taxis is determined by predator satiety proves the most suitable for describing the harpacticoid-diatom dynamics.
