Ecological interactions among phytoplankton occur in a moving fluid environment.

Diversity of growth rates maximizes phytoplankton productivity in an eddying ocean

We show that vertical nutrient flux depends both on the vertical motion within the eddying flow and varies nonlinearly with the growth rate of the phytoplankton itself.

Channel formation and branching is widely seen in physical systems where movement of fluid through a porous structure causes the spatiotemporal evolution of the medium in response to the flow, in turn causing flow pathways to evolve.
