In the present work, three poorly described vaginicolids, Pyxicola pusilla, Cothurnia ceramicola and Vaginicola tincta, were isolated from the surface of two freshwater/marine algae in China. In our study, the ciliature of Pyxicola and Vaginicola is revealed for the first time, demonstrating the taxonomic value of infundibular polykineties. The small subunit rDNA, ITS1-5.8S rDNA-ITS2 region and large subunit rDNA of the above species were sequenced for the first time. Phylogenetic analyses based on these genes indicated that Pyxicola and Cothurnia are closely related. -

The Macronuclear Genome of Stentor coeruleus Reveals Tiny Introns in a Giant Cell Abstract The giant, single-celled organism Stentor coeruleus has a long history as a model system for studying pattern formation and regeneration in single cells. Stentor [1, 2] is a heterotrichous ciliate distantly related to familiar ciliate models, such as Tetrahymena or Paramecium. The primary distinguishing feature of Stentor is its incredible size: a single cell is 1 mm long. Early developmental biologists, including T.H. Morgan [3], were attracted to the system because of its regenerative abilities—if large portions of a cell are surgically removed, the remnant reorganizes into a normal-looking but smaller cell with correct proportionality [2, 3]. -

Here, we have surveyed the literature involving planktonic protist interactions and gathered the information in a manually curated Protist Interaction DAtabase (PIDA). In total, we have registered ~2,500 ecological interactions from ~500 publications, spanning the last 150 years. -

UNIVERSITY OF ILLINOIS WATER RESOURCES CENTER 2535 Hydrosystems Laboratory Urbana, Illinois 61801 AUGUST 1977 ABSTRACT Water samples and free-living and sessite ciliated protozoa were col- lected at various distances above and below a stream that received runoff from a feedlot. No correlation was found between the species of protozoa recovered, water chemistry, location in the stream, or time of collection. Kenneth S. Todd, Jr'. EFFECTS OF FEEDLOT RUNOFF ON FREE-LIVING AQUATIC CILIATED PROTOZOA Final Report Project A-074-ILL, Office of Water Resources Research, Department of the Interior, August 1977, Washington, D.C., 13 p. KEYWORDS--*ciliated protozoa/feed lots runoff/*water pollution/water chemistry/Illinois/surface water INTRODUCTION The current trend for feeding livestock in the United States is toward large confinement types of operation. Most of these large commercial feedlots have some means of manure disposal and programs to prevent runoff from feed- lots from reaching streams. However, there are still large numbers of smaller feedlots, many of which do not have adequate facilities for disposal of manure or preventing runoff from reaching waterways. The production of wastes by domestic animals was often not considered in the past, but management of wastes is currently one of the largest problems facing the livestock industry. -
Based on SSU Rdna Sequences

KATZa,b aDepartment of Biological Sciences, Smith College, Northampton, Massachusetts 01063, and bProgram in Organismic and Evolutionary Biology, University of Massachusetts, Amherst, Massachusetts 01003, USA ABSTRACT. The ciliate Sorogena stoianovitchae, which can form a multicellular fruiting body, has been classi®ed based upon its ultrastructure and morphology: the oral and somatic infraciliature of S. stoianovitchae most closely resemble those of members of the order Cyrtolophosidida in the class Colpodea. We characterized the small subunit ribosomal DNA (SSU rDNA) gene sequence from S. stoianovitchae and compared this sequence with those from representatives of all ciliate classes. These analyses placed S. stoianovitchae as either sister to members of the class Nassophorea or Colpodea. In an in-group analysis, including all SSU rDNA sequences from members of the classes Nassophorea and Colpodea and representatives of appropriate outgroups, S. stoianovitchae was always sister to Platyophrya vorax (class Colpodea, order Cyrtolophosidida). However, our analyses failed to support the monophyly of the class Colpodea. Instead, our data suggest that there are essentially three unresolved clades: (1) the class Nassophorea; (2) Bresslaua vorax, Colpoda in¯ata, Pseudoplatyophrya nana, and Bursaria truncatella (class Colpodea); and (3) P. vorax and S. stoianovitchae (class Colpodea).

We evaluated sequence quality and de novo assembled a preliminary transcriptome, including 43.3 megabits and 119,141 transcripts. Then we obtained a final transcriptome, including 17.7 megabits and 35,560 transcripts, by removing contaminative and redundant sequences. Phylogenomic analysis based on a supermatrix with 132 genes comprising 53,873 amino acid residues and phylogenetic analysis based on SSU rDNA of 27 species were carried out herein to reveal the evolutionary relationships among six ciliate groups: Colpodea, Oligohymenophorea, Litostomatea, Spirotrichea, Hetero- trichea and Protocruziida. The topologies of both phylogenomic and phylogenetic trees are discussed in this paper. In addition, our results suggest that single-cell sequencing is a sound method of obtaining sufficient omics data for phylogenomic analysis, which is a good choice for uncultivable ciliates. -

This microcenosis, which actually existed as such within a very small, probably semiaquatic habitat, included the remains of about two bacteria species, four fungi (Palaeodikaryomyces baueri, Pithomyces-like conidia, capillitium-like hyphae, yeast cells) two euglenoids, two chlamydomonas (Chlamydomonas sp., Chloromonas sp.), two coccal green microalgae (Chlorellu sp., Chorzcystis-like cells), one zooflagellate, three testate amoebae (Centropyxis aculeata var. oblonga-like, Cyclopyxis eurystoma-like, Hyalosphenia baueri n. sp.), seven ciliates (Pseudoplatyophrya nana-like, Mykophagophrys rerricola-like, Cvrtolophosis mucicola-like, Paracondylostoma -
ABSTRACT Title of Dissertation: IDENTIFICATION, LIFE HISTORY
ABSTRACT Title of Dissertation: IDENTIFICATION, LIFE HISTORY, AND ECOLOGY OF PERITRICH CILIATES AS EPIBIONTS ON CALANOID COPEPODS IN THE CHESAPEAKE BAY Laura Roberta Pinto Utz, Doctor of Philosophy, 2003 Dissertation Directed by: Professor Eugene B. Small Department of Biology Adjunct Professor D. Wayne Coats Department of Biology and Smithsonian Environmental Research Center Epibiotic relationships are a widespread phenomenon in marine, estuarine and freshwater environments, and include diverse epibiont organisms such as bacteria, protists, rotifers, and barnacles. Despite its wide occurrence, epibiosis is still poorly known regarding its consequences, advantages, and disadvantages for host and epibiont. Most studies performed about epibiotic communities have focused on the epibionts’ effects on host fitness, with few studies emphasizing on the epibiont itself. The present work investigates species composition, spatial and temporal fluctuations, and aspects of the life cycle and attachment preferences of Peritrich epibionts on calanoid copepods in Chesapeake Bay, USA. Two species of Peritrich ciliates (Zoothamnium intermedium Precht, 1935, and Epistylis sp.) were identified to live as epibionts on the two most abundant copepod species (Acartia tonsa and Eurytemora affinis) during spring and summer months in Chesapeake Bay. Infestation prevalence was not significantly correlated with environmental variables or phytoplankton abundance, but displayed a trend following host abundance. Investigation of the life cycle of Z. intermedium suggested that it is an obligate epibiont, being unable to attach to non-living substrates in the laboratory or in the field. Formation of free-swimming stages (telotrochs) occurs as a result of binary fission, as observed for other peritrichs, and is also triggered by death or molt of the crustacean host. -

Systematic Index
Systematic Index The systematic index contains the scientific names of all taxa mentioned in the book e.g., Anisonema sp., Anopheles and the vernacular names of protists, for example, tintinnids. The index is two-sided, that is, species ap - pear both with the genus-group name first e.g., Acineria incurvata and with the species-group name first ( incurvata , Acineria ). Species and genera, valid and invalid, are in italics print. The scientific name of a subgenus, when used with a binomen or trinomen, must be interpolated in parentheses between the genus-group name and the species- group name according to the International Code of Zoological Nomenclature. In the following index, these paren - theses are omitted to simplify electronic sorting. Thus, the name Apocolpodidium (Apocolpodidium) etoschense is list - ed as Apocolpodidium Apocolpodidium etoschense . Note that this name is also listed under “ Apocolpodidium etoschense , Apocolpodidium ” and “ etoschense , Apocolpodidium Apocolpodidium ”. Suprageneric taxa, communities, and vernacular names are represented in normal type.
