A model for the effects of germanium on silica biomineralization in choanoflagellates
Marron, Alan Oliver; Chappell, Helen; Ratcliffe, Sarah; Goldstein, Raymond Ethan (Royal Society PublishingJournal of the Royal Society Interface, 2016-09-21)Silica biomineralization is a widespread phenomenon of major biotechnological interest. Modifying biosilica with substances like germanium (Ge) can confer useful new properties, although exposure to high levels of Ge ...

Aerotaxis in the closest relatives of animals
Kirkegaard, Julius Bier; Bouillant, A; Marron, Alan Oliver; Leptos, Kyriacos; Goldstein, Raymond Ethan (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
Kirkegaard, Julius Bier; Marron, Alan Oliver; Goldstein, Raymond Ethan (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 ...

The Evolution of Silicon Transport in Eukaryotes
Marron, Alan Oliver; Ratcliffe, Sarah; Wheeler, Glen L; Goldstein, Raymond Ethan; King, Nicole; Not, Fabrice; de, Vargas Colomban; Richter, Daniel J (Oxford University PressMolecular Biology and Evolution, 2016-10-11)Biosilicification (the formation of biological structures from silica) occurs in diverse eukaryotic lineages, plays a major role in global biogeochemical cycles, and has significant biotechnological applications. Silicon ...
