The role of tumbling frequency and persistence in optimal run-and-tumble chemotaxis
Julius B. Kirkegaard, Raymond E. Goldstein
One of simplest examples of navigation found in nature is run-and-tumble chemotaxis. Tumbles reorient cells randomly, and cells can drift toward attractants or away from repellents…
Mechanics and Variability of Cell Sheet Folding in the Embryonic Inversion of
Pierre A. Haas, Stephanie S. M. H. Höhn, Aurelia R. Honerkamp-Smith +2
Many embryonic deformations during development are the global result of local cell shape changes and other local active cell sheet deformations. Morphogenesis does not only therefo…
Filter-feeding, near-field flows, and the morphologies of colonial choanoflagellates
Julius B. Kirkegaard, Raymond E. Goldstein
Efficient uptake of 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 evo…
Aerotaxis in the Closest Relatives of Animals
Julius B. Kirkegaard, Ambre Bouillant, Alan O. Marron +2
As the closest unicellular relatives of animals, choanoflagellates serve as useful model organisms for understanding the evolution of animal multicellularity. An important factor i…
Motility of Colonial Choanoflagellates and the Statistics of Aggregate Random Walkers
Julius B. Kirkegaard, Alan O. Marron, Raymond E. Goldstein
We illuminate the nature of the three-dimensional random walks of microorganisms composed of individual organisms adhered together. Such are typified by…
