Morphology and Gene Sequence of Levicoleps biwae n. gen., n. sp. (Ciliophora, Prostomatida), a Proposed Endemic from the Ancient Lake Biwa, Japan
TLDR
Levicoleps biwae, a barrel‐shaped ciliate discovered in organic mud on the shore of Lake Biwa, Japan, is considered to represent a new genus and established a terminology for the colepid armour and selected four features for genus recognition: the number of armour tiers, the structure of the tier plates, the presence/absence of armour spines, and theNumber of adoral organelles.

Vorticella Linnaeus, 1767 (Ciliophora, Oligohymenophora, Peritrichia) is a grade not a clade: redefinition of Vorticella and the families Vorticellidae and Astylozoidae using molecular characters
TLDR
It is shown that Vorticella microstoma morphotypes, Astylozoon, and Opisthonecta form a well-supported, monophyletic clade, that is distinct from and basal to the family VortICEllidae containing other species of Vorticeslla. Expand
Growth and survival of peritrich ciliates in an urban stream
TLDR
By tracing the development of each Carchesium polypinum colony in the river, it was possible to estimate the actual growth rate of this species without considering the effect of immigration, and the rate of Vorticella microstoma increase was much lower than previously reported. Expand
Morphological and molecular characterization of Histiobalantium natans viridis (Ciliophora, Scuticociliatia).
TLDR
The morphological and molecular data show, with high support, a close relationship of Histiobalantium, Schizocalyptra and Pleuronema, supporting the family Pleuronematidae Kent, whose nearest relatives are the Cyclidiidae Ehrenberg. Expand
Two Oxytrichids from the Ancient Lake Biwa, Japan, with Notes on Morphogenesis of Notohymena australis (Ciliophora, Sporadotrichida)
TLDR
Two oxytrichid freshwater ciliates, Apoamphisiella tihanyiensis and Notohymena australis were recorded for the first time in Lake Biwa, a 4-million-year-old lake located at the Shiga Prefecture in Japan and morphology was investigated based on observations of live and protargol-impregnated material. Expand
The impact of nigorobuna crucian carp larvae/fry stocking and rice-straw application on the community structure of aquatic organisms in Japanese rice fields
TLDR
While Cladocera and Podocopida decreased in fish-stocked plots, Euglenales and Halteriida became more abundant there, and top-down or bottom-up effects of fish seemed to control these changes in community structure. Expand
Distributional survey of large branchiopods of rice paddies in Shiga Prefecture, Japan: a Lake Biwa Museum project based on lay amateur participation
TLDR
A distributional survey of the large branchiopod crustaceans of the rice paddies of Shiga Prefecture, Japan, was conducted by the Lake Biwa Museum in May and June of 1999 and 2000, with success due to the use of Field Reporters, who were able to provide a high degree of coverage of the study area. Expand
Morphology, morphogenesis and gene sequence of a freshwater ciliate, Pseudourostyla cristata (Ciliophora, Urostyloidea) from the ancient Lake Biwa, Japan.
TLDR
The present observations indicate that P. cristata has a wide geographic distribution, and possesses constant morphological and morphogenetic traits. Expand
Molecular phylogeny of the family Vorticellidae (Ciliophora, Peritrichia) using combined datasets with a special emphasis on the three morphologically similar genera Carchesium, Epicarchesium and
TLDR
P phylogenetic analyses of vorticellids based on the sequence of the small-subunit (SSU) rRNA gene, including one species of the genus Apocarchesium, for which no sequence has previously been reported are performed to explore further the phylogenetic relationship between the three morphologically similar genera. Expand
Cytological, genetic, and biochemical characteristics of an unusual non‐Chlorella photobiont of Stentor polymorphus collected from an artificial pond close to the shore of Lake Biwa, Japan
TLDR
Stentor polymorphus (Müller) Ehrenberg is a trumpet‐form ciliate with endosymbiotic green algae (photobionts) that has a form typical of Chlorella Beijerinck, with one chloroplast and a distinct pyrenoid. Expand
