Carlin (1943) proposed to throw the familiar name K. cochlearis into synonymy with K. stipitata Ehrenberg on the basis of a presumed error by Ehrenberg in drawing a K. quadrata dorsal pattern in a K. cochlearis outline.

Any body of standing water is likely to contain rotifers and Keratella cochlearis is probably the commonest and most widespread species in the world. Please see our brief essay. Polyarthra trigla was the most common species over the four seasons and proportionally most dominant in spring and autumn, whereas Cephalodella exigua and Keratella cochlearis were the most dominant species in winter and summer, respectively. While B. urceolaris showed a large selective advantage at low pH, this was reduced and both species fared better at near-neutral pH. Register.

(Ed.) In experiments and field studies we show that during part of their ontogeny fish larvae feed intensively on the common rotifer Keratella cochlearis, and that larval fish predation reduces rotifer spine length both through induction of shorter spines and selective predation on long-spined individuals. : 58360 (Download Help) Keratella cochlearis TSN 58360 Taxonomy and Nomenclature Kingdom: Animalia : Taxonomic Rank: Species : Synonym(s): Common Name(s): Taxonomic Status: Current Standing: valid Data Quality Indicators: Record Credibility Rating: unverified Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts.

Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. The main aim of this thesis was to investigate and describe the genetic diversity of one of the most common freshwater rotifer - Keratella cochlearis - in relation to its morphological variability. Specifically, this investigation examines the role of genetic factors in ex-plaining variance in spine development among members of the genus Keratella (K. cochlearis, K. hiemalis, and K. quad-rata).

This material is based upon work supported by the It was, thus, our goal to investigate the potential direct and indirect feeding relationships between some dominant freshwater ciliates of the genus Urotricha and the common co-occurring rotifer species Keratella cochlearis and Keratella quadrata.

Keratella cochlearis is within the scope of WikiProject Animals, an attempt to better organize information in articles related to animals and zoology.For more information, visit the project page. The second genus selected for analysis, Brachionus, has been the target of prior molecular studies. Keratella cochlearis var. The small cladocerans, Bos- rnina longirostris and Chydorus sphaericus also were resis- tant to predation by this copepod. 2021. We investigated the potential competition and feeding impact of the common rotifer species, Keratella cochlearis and K. quadrata, on the abundant prostomatid ciliates, Urotricha furcata and Balanion planctonicum, in laboratory batch culture experiments.
