[Microscale patchiness of the distribution of Harpacticoida as a result of trophotaxis].
A minimal conceptual model capable of explaining the microscale heterogeneity observed in the benthic trophic system harpacticoids-diatoms algae has been constructed. Alternative models of trophotaxis in predator-prey systems have been built in which a stimulus for predator movement is, correspondingly: (a) prey density, (b) attractant secreted by the prey, and (c) predator satiation. The analytical study demonstrated that the model in which predator taxis is determined by predator satiation is best suited for the description of population dynamics in system harpacticoids-diatoms algae.
