Fine structure of the female genital apparatus of Philodina (Rotifera, Bdelloidea)
Zoomorphology, 1982The organization of the female genital apparatus of the bdelloid rotifer Philodina roseola was analyzed by light and electron microscopy. It differs from that of the monogononts in several respects: the gonad is paired; in each gonad, the follicular layer completely surrounds the syncytial vitellarium and the cluster of ovocytes; the cytoplasmic ...

Hydrobiologia, 1991
Five clonal populations belonging to the parthenognetic species Macrotrachela quadricornifera were analyzed electrophoretically. The populations stemmed from samples collected from different environments paires geographically: water bodies (C,P,F) and terrestrial mosses (M1, M2).

Life histories of some species of Rotifera Bdelloidea
Hydrobiologia, 1983Nine species of Rotifera Bdelloidea have been cultured under laboratory conditions. The species were collected from two different environments: one group from water courses, the other from terrestrial mosses. Life tables have been determined and population dynamics parameters have been calculated.

Icelandic bdelloidea transcriptomic profiling through differential expression analysis
2021With the recent upsurge of Bdelloidea discoveries in permanently cold environments, members of the group represent prime candidates for better understanding adaptations to one of the most pervasive abiotic stressors; cold. Previous studies have highlighted the role of inducing cold stress tolerance through manipulation of the purine and energy ...

Holocene fossil Habrotrocha angusticollis (Bdelloidea: Rotifera) in North America
Journal of Paleolimnology, 1988Holocene fossil shells of the rotifer, Habrotrocha angusticollus (Bdelloidea: Rotifera) is reported from two peatlands in northern Ontario, Canada. H. angusticollis is a common component of the microfauna in Sphagnum peatlands and other wet mossy habitats. Our knowledge of the distribution and ecology of H.

Histochemical investigations of Rotifera Bdelloidea. I. Localization of cholinesterase activity
The Histochemical Journal, 1984Cholinesterase activity has been investigated in Rotifera Bdelloidea (Philodina roseola, Philodina tubercolata, Rotaria rotatoria and other unidentified species) by histochemical methods and in vivo observations. Parallel histological studies have been carried out. The enzyme specificity was tested by employing different substrates and inhibitors.

Zootaxa, 2015
Two new Bdellidae, Biscirus iranensis Paktinat-Saeej & Bagheri sp. nov. and Bdella farabii Paktinat-Saeej & Bagheri sp. nov., are described from northern Iran. The monotypic genus Neobiscirus considered a junior synonym of Biscirus, and its only species therefore considered Biscirus kobachidzei (Gomelauri, 1963) comb. nov.

Descriptions of three new species of Philodinida (Rotifera, Bdelloidea) from Korea
ZootaxaA taxonomic study on bdelloid rotifers collected from terrestrial habitats such as mosses and leaf litter at two different locations in Korea resulted in three new species, Habrotrocha changhoi n. sp., H. microcornis n. sp. and Philodina undulata n. sp. Habrotrocha changhoi n. sp. is easily distinguished from its congeners by five small dorsal humps on

Opinion paper: Are lemnisci and proboscis present in the Bdelloidea?
1998Phylum Rotifera is typically defined by the presence of a (a) primary body cavity, (b) specialized ciliary apparatus called the corona located at the anterior end, and (c) jaw apparatus of hard parts (trophi) (e.g., de Beauchamp, 1965). To this list of characters Nielsen (1995) added (d) an intracytoplasmic skeletal lamina, (e) a retrocerebral ...
