Gause's exclusion principle revisited: artificial modified species and competition
, 2000 Gause's principle of competition between two species is studied when one of them is sterile. We study the condition for total extinction in the niche, namely, when the sterile population exterminates the native one by an optimal use of resources.

"Paramecium aurelia and mutation"
Experimental Biology and Medicine, 1904 The ordinary species is Paramecium caudatum; superficially, it resembles P. aurelia. The latter differs from the former in smaller size, in rounded instead of attenuated posterior end, and in the possession of two instead of one micronucleus. The last is generally regarded as the most important difference between the two species. In March, 1905, a pair

Senescence in vitro and ionising radiations—the human diploid fibroblast model [PDF]
, 1981 The influence of ionising radiations on ageing is still controversial. Since Hayflick established the concept that diploid cells have finite lifespan in vitro, human diploid fibroblast (HDF) cultures have been recognised as a potent experimental model ...

Macronuclear DNA in Stentor coeruleus: a first approach to its characterization [PDF]
, 2017 The macronuclei of Stentor coeruleus were isolated on a discontinuous sucrose gradient and their DNA was purified by conventional methods. The GC content was 32 mole%. The DNA banded as a single peak on analytical ultracentrifugation at 1·691 g/cm3.

CORTICAL ULTRASTRUCTURE OF PARAMECIUM AURELIA
Journal of Cell Biology, 1969 Two methods have been devised for the isolation of large quantities of purified pellicles (cortical layers) of Paramecium aurelia. Pellicles isolated by both procedures, when examined by electron microscopy, were found to contain ciliary basal bodies ...

Thermal response of freshwater ciliates: Can they survive at elevated lake temperatures?
Freshwater Biology, Volume 69, Issue 9, Page 1245-1260, September 2024.Abstract Ciliates are a well‐defined, species‐rich, versatile group of heterotrophic and mixotrophic protists. Their response to increased temperature during global warming is critical for the structure and functioning of freshwater food webs. I conducted a meta‐analysis of the literature from field studies and experimental evidence to assess the ...

Methylation of Replicating and Nonreplicating DNA in the Ciliate \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]
, 1989 Methylation of adenine in replicating and nonreplicating DNA of the ciliate Tetrahymena thermophila was examined. In growing cells, 87% of the methylation occurred on the newly replicated daughter strand, but methylation was also detectable on the ...

Competition between mixo‐ and heterotrophic ciliates under dynamic resource supply
Ecosphere, Volume 15, Issue 7, July 2024.Abstract The outcome of species competition strongly depends on the traits of the competitors and associated trade‐offs, as well as on environmental variability. Here, we investigate the relevance of consumer trait variation for species coexistence in a ciliate consumer–microalgal prey system under fluctuating regimes of resource supply.
