delimiting species boundaries within a paraphyletic species complex: insights from morphological, genetic, and molecular data on paramecium sonneborni (paramecium aurelia species complex, ciliophora, protozoa). | the demarcation of boundaries between protist species is often problematic because of the absence of a uniform species definition, the abundance of cryptic diversity, and the occurrence of convergent morphology. the ciliates belonging to the paramecium aurelia complex, consisting of 15 species, are a good model for such systematic and evolutionary studies. one member of the complex is p. sonneborni, previously known only from one stand in texas (usa), but recently found in two new sampling sites ... | 2015 | 26277215 |
the first european stand of paramecium sonneborni (p. aurelia complex), a species known only from north america (texas, usa). | p. aurelia is currently defined as a complex of 15 sibling species including 14 species designated by sonneborn (1975) and one, p. sonneborni, by aufderheide et al. (1983). the latter was known from only one stand (texas, usa). the main reason for the present study was a new stand of paramecium in cyprus, with strains recognized as p. sonneborni based on the results of strain crosses, cytological slides, and molecular analyses of three loci (its1-5.8s-its2-5'lsu rdna, coi, cytb). the new stand o ... | 2014 | 24882685 |
identification of the basal bodies and kinetodesmal fibers in living cells of paramecium tetraurelia sonneborn, 1975 and paramecium sonneborni aufderheide, daggett & nerad, 1983. | critical use of nomarski dic optics and a rotocompressor permits basal bodies and kinetodesmal fibers to be visualized in the cortices of living paramecium tetraurelia and paramecium sonneborni. the identification of these structures is confirmed by the correspondence of the images obtained by dic optics of living cells and by brightfield optics of fixed cells stained by the fernández-galiano silver technique. examination of cells carrying cortical inversions (portions of the cortex rotated 180 ... | 1986 | 3959010 |
