Genetic diversity in the Paramecium aurelia species complex.
Current understanding of the population genetics of free-living unicellular eukaryotes is limited, and the amount of genetic variability in these organisms is still a matter of debate. We characterized-reproductively and genetically-worldwide samples of multiple Paramecium species belonging to a cryptic species complex, Paramecium aurelia, whose species have been shown to be reproductively isol...
متن کاملDistribution of species of the Paramecium aurelia complex in Spain.
At present 15 species of the Paramecium aurelia complex are known world-wide (Sonneborn 1975, Aufderheide et al. 1983). Some species are cosmopolitan (P. primaurelia, P. biaurelia, P. tetraurelia, and P. sexaurelia), while others have been found only in single localities (e.g., P. quadecaurelia). Studies concerning their distribution, however, were carried out unevenly in different areas. For i...
متن کاملNew stands of species of the Paramecium aurelia complex in Africa and Europe.
The relevance of geographical distribution and the roles of dispersal and spatial isolation during the speciation of microorganisms are nowadays of great interest. The Paramecium aurelia species complex is a perfect model system to explore these questions given its long history as a study subject and broad distribution. However, the world-wide distribution of the Paramecium aurelia complex (Cil...
متن کاملInterspecies Relationships in the Paramecium aurelia Complex: Acid Phosphatase Variation1
Up to five zones of acid phosphatase activity appear in gels after electrophoresis of detergent-treated extracts from 13 of the 14 species of the Paramecium aurelia complex. The overall pattern is somewhat similar for all species; differences in intensity and mobility of individual zones permit the grouping of these sibling species into eight groups. All 14 species can be identified using the p...
متن کاملSpecies of the Paramecium aurelia complex in Russia (western region of European Russia) with molecular characteristics of Paramecium novaurelia.
The presence of P. primaurelia, P. biaurelia, P. triaurelia, and P. novaurelia of the P. aurelia complex was revealed in the studied region of Russia. RAPD-PCR fingerprints (band patterns) of newly identified P. novaurelia strains from Russia were compared to those characteristic for the other chosen European strains of the species. The strains revealed intraspecific polymorphism as several gro...
