Molecular phylogeny of choanoflagellates, the sister group to Metazoa
Choanoflagellates are single-celled aquatic flagellates with a unique morphology consisting of a cell with a single flagellum surrounded by a “collar” of microvilli. They have long interestedExpand

Higher Level Taxonomy and Molecular Phylogenetics of the Choanoflagellatea
ABSTRACT. The choanoflagellates (Choanoflagellatea) comprise a major group of nanoflagellates, which are ubiquitous in the aquatic environment. Recent molecular phylogenies have shown them to be theExpand

A comparison of the growth kinetics of six marine heterotrophic nanoflagellates fed with one bacterial species.
The growth kinetics of 6 species of marine heterotrophic nanoflagellates (5 to 13 mum) were compared. The maximum specific growth rates (mu(max)) of the flagellates ranged from 0.035 to 0.21 h-1 andExpand

Effect of inhibitors on calcium carbonate deposition mediated by freshwater algae
Nine green algae, a diatom and three cyanobacteria were shown to precipitate CaCO3 in batch culture, when grown in the light in a hard water medium containing 68 mg L−1 soluble calcium. TheExpand

Silicification of 'cell walls' of certain protistan flagellates
Silica deposition is described for two protistan flagellates, Synura petersenii (Chrysophyceae, algae) and Stephanoeca diplocostata (Choanoflagellida, Protozoa). Both taxa produce silica unitsExpand

A six-gene phylogeny provides new insights into choanoflagellate evolution.
Recent studies have shown that molecular phylogenies of the choanoflagellates (Class Choanoflagellatea) are in disagreement with their traditional taxonomy, based on morphology, and thatExpand

Three-dimensional images of choanoflagellate loricae
Choanoflagellates are unicellular filter-feeding protozoa distributed universally in aquatic habitats. Cells are ovoid in shape with a single anterior flagellum encircled by a funnel-shaped collar ofExpand
