Abstract
A mathematical model of small organism diffusion around an attractive center is presented. The diffusion equation includes a forcing term which creates a virtual flow of organisms toward the center. Owing to the attractive force, the organisms tend to collect in “swarms” or “patches” notwithstanding the diffusive motion of surrounding water.
