The ocean’s nitrogen is largely fixed by cyanobacteria, including Trichodesmium, which
forms aggregates comprising hundreds of filaments arranged in organized architectures. …

Phytoplankton come in a stunning variety of shapes but elongated morphologies dominate—typically
50% of species have aspect ratio above 5, and bloom-forming species often form …

Classical turbulence theory assumes that energy transport in a 3D turbulent flow proceeds
through a Richardson cascade whereby larger vortices successively decay into smaller ones. …

We investigate flow pattern formation and viscosity reduction mechanisms in active fluids by
studying a generalized Navier-Stokes model that captures the experimentally observed bulk …

The ecological interaction between bacteria and sinking particles, such as bacterial degradation
of marine snow particles, is regulated by their encounters. Current encounter models …

Recent experiments demonstrate the importance of substrate curvature for actively forced
fluid dynamics. Yet, the covariant formulation and analysis of continuum models for …

We discuss a minimal generalization of the incompressible Navier-Stokes equations to
describe the complex steady-state dynamics of solvent flow in an active suspension. To account …

Biofilm formation is the most successful survival strategy for bacterial communities. In the
biofilm lifestyle, bacteria embed themselves in a self-secreted matrix of extracellular polymeric …

Properties of microbial communities emerge from the interactions between microorganisms
and between microorganisms and their environment. At the scale of the organisms, microbial …

Under favorable conditions, microscopic phytoplankton cells dwelling in the oceans can
divide rapidly and reach high concentrations, forming blooms that span kilometers and last for …
