One major adaptive constraint over formation and use of heuristics involves a ciliate 's initial subjective bias, responsiveness, or preparedness, as defined by Stevens' Law of subjective stimulus intensity, for perceiving the meaningfulness of mechanical pressures accompanying cell-cell contacts and additional perimating events. This bias controls durations and valences of nonassociative learning, search rates for appropriate mating strategies, potential net reproductive payoffs, levels of social honesty and deception, successful error diagnosis and correction of mating signals, use of insight or analysis to solve mating dilemmas, bioenergetics expenditures, and governance of mating decisions by classical or quantum statistical mechanics.

I now report this same social bias also differentially affects the spatiotemporal sparseness, as measured with metric entropy, of ciliate heuristics. Sparseness plays an important role in neural systems through optimizing the specificity, efficiency, and capacity of memory representations. The present. Act together — implications of symbioses in aquatic ciliates.

Full Text Available Mutual interactions in form of symbioses can increase the fitness of organisms and provide them with the capacity to occupy new ecological niches. The formation of obligate symbioses allows for rapid evolution of new life forms including multitrophic consortia.

Microbes are important components of many known endosymbioses and their short generation times and strong potential for genetic exchange may be important drivers of speciation. Hosts provide endo- and ectosymbionts with stable, nutrient-rich environments and protection from environmental stresses. This is of particular importance in aquatic ecosystems, which are often highly variable, harsh and nutrient-deficient habitats. Thus it is not surprising that symbioses are widespread in both marine and freshwater environments. Symbioses in aquatic ciliates are good model systems for exploring symbiont-host interactions.

Many ciliate species are globally distributed and have been intensively studied in the context of plastid evolution. Their relatively large cell size offers an ideal habitat for numerous microorganisms with different functional traits including commensalism and parasitism. Phagocytosis facilitates the formation of symbiotic relationships, particularly since some ingested microorganisms can escape the digestion. For example, photoautotrophic algae and methanogens represent endosymbionts that greatly extend the biogeochemical functions of their hosts.

Consequently, symbiotic relationships between protists and prokaryotes are widespread and often result in new ecological functions of symbiotic communities. This enables ciliates to thrive under a wide range of environmental conditions including ultraoligotrophic or anoxic habitats. We summarize the current understanding of this exciting research topic to identify the many areas in which knowledge is lacking and to stimulate future research by providing an overview on new methodologies and by formulating a number of emerging.

The mitochondrial genomes of the ciliates Euplotes minuta and Euplotes crassus. Graaf, R. These genomes are rather similar because the ciliates analysed Tetrahymena spp. Here we study the mitochondrial.

The most prominent protistologists who worked with ciliates from the Leeuwenhoek time up to the beginning of the XX century are mentioned. Their achievements in ciliatology and especially in taxonomy of ciliates are briefly discussed on the basis of the original literature and reviews, published during the last years.

Phytoplankton growth inhibited by the toxic and bacterivorous ciliate Uronema marinum Protozoa, Ciliophora.

Rumen ciliate protozoal fauna of native sheep, friesian cattle and dromedary camel in Libya. Rumen ciliate species and composition were surveyed on the native sheep, Friesian-cattle and dromedary one-humped camels kept in Libya. As a result of survey, 5 genera including 14 species with 5 formae in native sheep, 9 genera including 27 species with 6 formae in Friesian-cattle and 6 genera including 13 species and 7 formae in dromedary camels were identified.

All of the ciliate species and their percentage composition detected from the Libyan sheep and cattle in this examination were similar to those found from corresponding animals in the other countries. Libyan camels lacked some peculiar ciliate species found from camels in the other countries, but had many cosmopolitan species common with those in the domestic ruminants, suggesting that ciliate faunae of camel are easily affected by the other domestic ruminants kept together.

A comparative in-silico analysis of autophagy proteins in ciliates. A set of eukaryotic genes called autophagy-related genes ATGs orchestrate this highly elaborative process. The existence of these genes and the role they play in different eukaryotes are well-characterized. However, little is known of their role in some eukaryotes such as ciliates. Here, we report the computational analyses of ATG genes in five ciliate genomes to understand their diversity.

Our results show that Oxytricha trifallax is the sole ciliate which has a conserved Atg12 conjugation system Atg5-AtgAtg Interestingly, Oxytricha Atg16 protein includes WD repeats in addition to its N-terminal Atg16 domain as is the case in multicellular organisms. Additionally, phylogenetic analyses revealed that E2-like conjugating protein Atg10 is only present in Tetrahymena thermophila. We fail to find critical autophagy components Atg5, Atg7 and Atg8 in the parasitic ciliate Ichthyophthirius multifiliis.

Contrary to previous reports, we also find that ciliate genomes do not encode typical Atg1 since all the candidate sequences lack an Atg1-specific C-terminal domain which is essential for Atg1 complex formation. Consistent with the absence of Atg1, ciliates also lack other members of the Atg1 complex.

However, the presence of Atg6 in all ciliates examined here may rise the possibility that autophagosome formation could be operated through Atg6 in ciliates , since Atg6 has been shown as an alternative autophagy inducer. In conclusion, our results highlight that Atg proteins are partially conserved in ciliates. This may provide a better understanding for the autophagic destruction of the parental macronucleus, a developmental process also known as programmed nuclear death in ciliates.

We examine the life, work, and legacy of Clara Haber, nee Immerwahr, who became the first woman to earn a doctorate from the University of Breslau, in In she married the chemist Fritz Haber. With no employment available for female scientists, Clara freelanced as an instructor in the continued education of women, mainly housewives, while struggling not to become a housewife herself. Her duties as a designated head of a posh household hardly brought fulfillment to her life. The outbreak of WWI further exacerbated the situation, as Fritz Haber applied himself in extraordinary ways to aid the German war effort.

The night that he celebrated the "success" of the first chlorine cloud attack, Clara committed suicide. We found little evidence to support claims that Clara was an outspoken pacifist who took her life because of her disapproval of Fritz Haber's involvement in chemical warfare. We conclude by examining "the myth of Clara Immerwahr" that took root in the s from the perspective offered by the available scholarly sources, including some untapped ones.

Effect of salt and urban water samples on bacterivory by the ciliate , Tetrahymena thermophila. St Denis, C. The effect of road salt on the eating of bacteria or bacterivory by the ciliate , Tetrahymena thermophila, was followed in non-nutrient Osterhout's solution with Escherichia coli expressing green fluorescent protein. Bacterivory was impaired at between 0. By contrast, E. In nutrient medium, salt was not toxic and the ciliates grew.

After growth in salt, ciliates consumed bacteria in 0. Bacteria and ciliates were added to urban creek samples to compare their capacity to support exogenous bacterivory. Even though samples were collected weekly for a year and be expected to have fluctuating salt levels as a result of deicing, all creek samples supported a similar level of bacterivory. The effects of different fertilizers on the ciliate communities of forests. The influence of lime, mineral fertilizers and different composts on the ciliate communities Protozoa: Ciliophora of very acidified spruce forests were tested.

In succession culture experiments species range, total numbers, abundance and dominance structure of the ciliate communities showed continued changes over a 90 day period. This method offers the opportunity not only to diagnose, but also to quantify effects of soil treatments. Investigations at the ARINUS-site Schluchsee Black Forest showed the following results: Liming led to a greater change in the ciliate communities than fertilization with magnesium-sulphate and ammonia-sulphate.

Liming and treatment with compost, made from household garbage, and compost, made from chopped wood on the Beimerstetten site Swabian Alb led also to remarkably changes in the ciliate communities. The total ciliate numbers of the household garbage area were very low. In contrast, the ciliate community of the chopped wood compost areas were characterized by a great species number and high abundances of spirotrichuous ciliates , especially Halteria grandinella.

Diverse modes of reproduction in the marine free-living ciliate Glauconema trihymene. Full Text Available Abstract Background Most free-living ciliates reproduce by equal fission or budding during vegetative growth. In certain ciliates , reproduction occurs inside the cyst wall, viz. Radiophrya spp. Results In addition to equal fission, asymmetric binary division and reproductive cysts were discovered in the free-living bacterivorous scuticociliate Glauconema trihymene Thompson, Asymmetric division is an innate physiological state that can be induced by sufficient food, and the higher the food concentration, the longer the asymmetric division persists.

During asymmetric division, nuclear and somatic structures divide with transiently arrested cytokinesis and variable positioning of macronuclei.

Conclusions The asymmetric division in G. The coexistence of multiple modes of reproduction may represent a previously undescribed reproductive strategy for ciliates living on food patches in coastal waters. This may also be indicative of similar reproductive strategies among other polyphenic ciliates , which have not been intensively studied. Asymmetric division provides a special opportunity for studying ciliates ' phenotypic plasticity and may also illuminate the origins of multicellularity. Ciliated protozoa in the impact zone of the Uzhgorod treatment plant.
