Study on the role of microtubules related to the nuclear behaviors during conjugation of paramecium caudatum [PDF]
, 2002 In most organisms, microtubules are involved in the migration of the pronuclei during fertilization. Fertilization process of Paramecium caudatum includes two stages of nuclear migration. One is a selection of meiotic products.

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.

Information and Meaning in Life, Humans and Robots [PDF]
, 2005 Information and meaning exist around us and within ourselves, and the same information can correspond to different meanings. This is true for humans and animals, and is becoming true for robots.

Host control and nutrient trading in a photosynthetic symbiosis [PDF]
arXiv, 2015 Photosymbiosis is one of the most important evolutionary trajectories, resulting in the chloroplast and the subsequent development of all complex photosynthetic organisms. The ciliate Paramecium bursaria and the alga Chlorella have a well established and well studied light dependent endosymbiotic relationship.

The mechanics of gravitaxis inParamecium [PDF]
Journal of Experimental Biology, 2010 SUMMARYAn analysis of swimming patterns in the ciliate Paramecium shows that the ability to swim preferentially upwards (negative gravitaxis) is primarily the result of upwardly curving trajectories. The trajectory characteristics are consistent with those produced by mechanical orientation. Cell profile measurements from microscope images suggest that

Biological Fluid Mechanics Under the Microscope: A Tribute to John Blake
, 2018 John Blake (1947--2016) was a leader in fluid mechanics, his two principal areas of expertise being biological fluid mechanics on microscopic scales and bubble dynamics. He produced leading research and mentored others in both Australia, his home country,

THE EFFECT OF CYANIDE ON RESPIRATION IN PARAMECIUM CAUDATUM AND PARAMECIUM AURELIA
The Biological Bulletin, 1945 1. The oxygen consumption in Paramecium caudatum and Paramecium aurelia is partially inhibited by potassium cyanide.2. The extent of inhibition by cyanide is dependent upon the food content of the organisms as well as upon the concentration of cyanide in the solution.3. In P.

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 ...

The Biological Bulletin, 1947 1. The feeding apparatus in Paramecium consists of a shallow ciliated groove, a ciliated tube which leads into the body, and a bundle Of fibers (esophageal fibers) which extend from the tube nearly to the posterior end of the body. The tube is composed of an outer part (the vestibulum) and an inner part (the pharynx).2.
