Heterotrophic nanoflagellates are the main consumers of bacteria and picophytoplankton in
the ocean and thus play a key role in ocean biogeochemistry. They are found in all major …

In the past decade, the volvocine green algae, spanning from the unicellular
Chlamydomonas to multicellular Volvox, have emerged as model organisms for a number of …

Active suspensions, such as suspensions of self-propelled microorganisms and related
synthetic microswimmers, are known to undergo complex dynamics and pattern formation as …

The hydrodynamics of an archetypal low-Reynolds number swimmer, called “squirmer,”
near a wall has been numerically studied. For a single squirmer, depending on the …

The metabolic rate of organisms may be viewed as a basic property from which other vital
rates and many ecological patterns emerge and that follows a universal allometric mass …

We use numerical simulations to address locomotion at zero Reynolds number in
viscoelastic (Giesekus) fluids. The swimmers are assumed to be spherical, to self-propel …

The boundary behavior of axisymmetric microswimming squirmers is theoretically explored
within an inertialess Newtonian fluid for a no-slip interface and also a free surface in the …

In 1952, Lighthill introduced the simplest possible model of a swimming micro-organism of
finite size, intended as a model of a single-celled protozoan covered in beating cilia. The …

A number of swimming microorganisms, such as ciliates (Opalina) and multicellular colonies
of flagellates (Volvox), are approximately spherical in shape and swim using beating arrays …

The self-propulsion of a spherical squirmer–a model swimming organism that achieves
locomotion via steady tangential movement of its surface–is quantified across the transition …
