Diverse DNA transposons in rotifers of the class Bdelloidea [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2005 We surveyed the diversity, structural organization, and patterns of evolution of DNA transposons in rotifers of the class Bdelloidea, a group of basal triploblast animals that appears to have evolved for millions of years without sexual reproduction ...

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.

Oogenesis in Macrotrachela quadricornifera (Rotifera, Bdelloidea)
Hydrobiologia, 1993Bdelloids reproduce via obligate apomictic parthenogenesis. Oogenesis occurs through two subsequent equational divisions, with the extrusion of two polar bodies. Although the morphology of the bdelloid reproductive apparatus has been previously described, the eutely of the germarium has never been investigated.

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.

Journal of Natural History, 2004 We describe some rare epizoic rotifers found on Potamon fluviatile (Herbst, 1785) from Italy. Three species are discussed: Lecane branchicola (Piovanelli, 1903) (Monogononta, Lecanidae; new synonym: L.

The Philodinavidae (Rotifera Bdelloidea): a special family
Hydrobiologia, 1998Here we focus on the fine morphology and present observations on the biology of representatives of family Philodinavidae. Philodinavus paradoxus and Henoceros falcatus were collected and cultured under laboratory conditions. Rotifers of both species are tiny, about 200 μm long, have protrudable trophi and creep with leech-like movements.

Iranian Cunaxidae (Acari: Prostigmata: Bdelloidea): Part 2. Subfamily Cunaxinae
Journal of Natural History, 2011 The Iranian Cunaxinae dealt with in this paper comprise three known species of one genus. They are Cunaxa grobleri den Heyer, 1979a, Cunaxa capreolus (Berlese, 1889) and Cunaxa setirostris (Hermann, 1804). The first description of a male of Cunaxa capreolus is provided. The first two species are reported for the first time from Iran.

New records of rare Bdelloidea and Monogononta Rotifers in gravel streams
Archiv Für Hydrobiologie, 1995Rare rotifer species have been newly found in two different gravel streams (Oberer Seebach, Austria; and Afon Mynach, North Wales, Great Britain). The taxonomy and habitat distribution is revised, and confirmed for: Philodinavus paradoxus (MURRAY), Henoceros falcatus (MILNE), Microcodides chlaena (GOSSE), Proalinopsis caudatus (COLLINS), Dicranophorus ...

Functional morphology of the muscles in Philodina sp. (Rotifera: Bdelloidea)
Hydrobiologia, 2000Whole-mounts of Philodina sp., a bdelloid rotifer, were stained with fluorescent-labeled phalloidin to visualize the musculature. Several different muscle types were identified including incomplete circular bands, coronal retractors and foot retractors.
