The Surface Antigens of Paramecium aurelia [PDF]
Journal of General Microbiology, 1956 SUMMARY: A surface antigen preparation obtained from Paramecium aurelia absorbs from a concentrated antiserum approximately 74% of the total antibody absorbed by the intact animal. An antiserum prepared against this preparation immobilized P. aurelia of the same serotype.

A Ninth Variety of Paramecium aurelia [PDF]
Journal of General Microbiology, 1954 SUMMARY: A new variety of Paramecium aurelia—variety 9—containing two mating types XVII and XVIII, has been identified from seven samples of water collected in Scotland. Variety 9 belongs to the group A varieties in the Sonneborn system of classification, but shows no interparietal mating reactions.

Food niches of planktonic rotifers: Diversification and implications
Limnology and Oceanography, Volume 67, Issue 10, Page 2218-2251, October 2022., 2022 Abstract The diverse diets of common planktonic rotifers are described in detail from field and laboratory observations and experiments. Also considered are methodological approaches, rotifer feeding mechanisms, and the availability in natural waters of less well‐known food items (detritus, picoplankton, protozoans).

Bacterial symbiosis in ciliates (Alveolata, Ciliophora): Roads traveled and those still to be taken
Journal of Eukaryotic Microbiology, Volume 69, Issue 5, September/October 2022., 2022 Abstract The diversity of prokaryotic symbionts in Ciliophora and other protists is fascinatingly rich; they may even include some potentially pathogenic bacteria. In this review, we summarize currently available data on biodiversity and some morphological and biological peculiarities of prokaryotic symbionts mainly within the genera Paramecium and ...

Paramecium epigenetics in development and proliferation
Journal of Eukaryotic Microbiology, Volume 69, Issue 5, September/October 2022., 2022 Abstract The term epigenetics is used for any layer of genetic information aside from the DNA base‐sequence information. Mammalian epigenetic research increased our understanding of chromatin dynamics in terms of cytosine methylation and histone modification during differentiation, aging, and disease.

Ciliate research: From myth to trendsetting science
Journal of Eukaryotic Microbiology, Volume 69, Issue 5, September/October 2022., 2022 Abstract This special issue of the Journal of Eukaryotic Microbiology (JEM) summarizes achievements obtained by generations of researchers with ciliates in widely different disciplines. In fact, ciliates range among the first cells seen under the microscope centuries ago.

Ecology and Evolution, Volume 12, Issue 2, February 2022., 2022 Climatic changes are predicted to alter mean temperatures and fluctuations in temperature. Here, we show that increased mean temperatures are generally associated with negative impacts on biodiversity. However, these negative impacts can be partially reduced if fluctuations in temperature are maintained. Abstract Future climate changes are predicted to

Body size and shape responses to warming and resource competition
Functional Ecology, Volume 35, Issue 7, Page 1460-1469, July 2021., 2021 A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Body size is a fundamental trait that impacts many aspects of species biology and ecology. It is, in turn, influenced by a suite of environmental factors, and often decreases with warming.

Density-and trait-mediated effects of a parasite and a predator in a tri-trophic food web [PDF]
, 2014 1. Despite growing interest in ecological consequences of parasitism in food webs, relatively little is known about effects of parasites on long-term population dynamics of non-host species or about whether such effects are density- or trait- mediated ...

Molecular epidemiology of African sleeping sickness [PDF]
, 2009 Human sleeping sickness in Africa, caused by Trypanosoma brucei spp. raises a number of questions. Despite the widespread distribution of the tsetse vectors and animal trypanosomiasis, human disease is only found in discrete foci which periodically give ...
