All four series of experiments show that the general `time-periodicity' of rhythms and endomixis in Paramecium aurelia is the same in the several races which have been studied under the following environmental conditions:1.

Microbes, mathematics, and models [PDF]
Microbial model systems have a long history of fruitful use in fields that include evolution and ecology. In order to develop further insight into modelling practice, we examine how the competitive exclusion and coexistence of competing species have been

Paramecium tredecaurelia: A Unique Non-Polymorphic Species of the P. aurelia spp. Complex (Oligohymenophorea, Ciliophora) [PDF]
New stands of Paramecium tredecaurelia, a rare species of the P. aurelia spp. complex, were identified in Thailand and Madagascar on the basis of mating reactions and molecular markers (rDNA and mtDNA).

Population Growth in Space and Time [PDF]
How great an effect does self-generated spatial structure have on logistic population growth? Results are described from an individual based model (IBM) with spatially localized dispersal and competition, and from a deterministic approximation to the IBM

Intraspecies Variability in the Esterases and Acid Phosphatases of Four Species of the Paramecium aurelia Complex 1 [PDF]
One hundred eighty-eight stocks of Paramecium primaurelia. P. biaurelia, P. tetraurelia. and P. octaurelia were grown axenically and screened for variation in four different esterases and acid phosphatase using starch gel electrophoresis.

Esterase Variants in Four Species of the Paramecium aurelia Complex 1 [PDF]
One hundred eighty-eight stocks of Paramecium primaurelia, P. biaurelia, P. tetraurelia , and P. octaurelia were grown axenically and tested for five esterases, visualized by starch gel electrophoresis, in a search for variant stocks.

STUDIES ON THE CHARACTERIZATION AND STRUCTURE OF THE IMMOBILIZATION ANTIGENS OF PARAMECIUM AURELIA.
1. Methods for the extraction and purification of the immobilization antigens of Paramecium aurelia have been developed. 2. The immobilization antigen was shown to be a protein of molecular weight 250000.

Esterase Variations between the 14 Syngens of PARAMECIUM AURELIA under Axenic Growth.
Under axenic growth all 14 syngens of Paramecium aurelia have 4 types of esterases. The three major types (A, B and cathodal C) vary independently in electrophoretic mobility among the syngens. Using these three esterases, stocks can be keyed to a syngen,
