Abstract.The speciesParamecium aureliasensu latu, containing 15 sexually isolated subspecies (syngens), is the classic example of a sibling species complex in the ciliates. Using DNA sequence comparison, it is now possible to see whether this example parallels other studied sibling species complexes.

A Magnesium Current in Paramecium

Science, 1990
Recent reappraisals of the role of ionized magnesium in cell function suggest that many cells maintain intracellular free Mg 2+ at low concentrations (0.1 to 0.7 mM) and that external agents can influence cell function via changes in intracellular Mg 2+ concentration.

Morphology and Cytology of Paramecium

1986
Throughout the world, paramecia have been intensively studied with the electron microscope (EM), and a number of these micrographs—many original—are included in this and other chapters.

Chemosensory transduction in Paramecium

European Journal of Protistology, 1998
Summary Paramecium tetraurelia is attracted and repelled by a variety of chemical stimuli. The attractants probably signify the presence of nutrients. For attractants, there are at least three signal transduction pathways that all lead to a hyperpolarization of the cell that results in relatively fast and smooth swimming. The three pathways differ in
