Aerotaxis in the closest relatives of animals
(eLife Sciences Publications LtdeLife, 2016-11-24)
As the closest unicellular relatives of animals, choanoflagellates serve as useful model organisms for understanding the evolution of animal multicellularity. An important factor in animal evolution was the increasing ocean ...
Motility of Colonial Choanoflagellates and the Statistics of Aggregate Random Walkers
(American Physical SocietyPhysical Review Letters, 2016-01-22)
We illuminate the nature of the three-dimensional random walks of microorganisms composed of individual organisms adhered together. Such aggregate random walkers are typified by choanoflagellates, eukaryotes that are the ...
Filter-feeding, near-field flows, and the morphologies of colonial choanoflagellates
(American Physical SocietyPhysical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2016-11-01)
Efficient uptake of prey and nutrients from the environment is an important component in the fitness of all microorganisms, and its dependence on size may reveal clues to the origins of evolutionary transitions to ...
