Hydrobiologia, 1983
The biogeography of rotifers is discussed in light of general biogeographical concepts. It is argued that, in spite of considerable abilities for passive dispersal, vicariance can develop well in this group. Examples selected from the Brachionidae illustrate the high levels of endemicity found in Australia and South America, while the Indian ...

Trophi Structure in Bdelloid Rotifers
Hydrobiologia, 2005Bdelloids show a rather uniform morphology of jaws (trophi), named ramate. The most recognizable feature is the presence of a series of teeth forming unci plates. The unci are not uniform in size; each plate has 1–10 major median teeth. Using SEM pictures of trophi and data from the literature, we analyzed the number of major unci teeth in relation to ...

Rotifers are widespread and abundant in aquatic ecosystems and are valuable live feeds in aquaculture and fisheries. They are particularly useful in evaluating full life cycle and population-level effects in response to pollutant exposures. Rotifers have, therefore, been considered as a promising species in aquatic ecotoxicology.

The Journal of Parasitology, 2002
Seven species of rotifers representing 6 genera, Epiphanes, Plationus, Asplanchna, Philodina species A, Philodina species B. Platyias, and Brachionus, were exposed to Giardia cysts isolated from the feces of experimentally infected holstein calves. Giardia cysts were prestained with a fluorescein isothiocyanate-conjugated monoclonal antibody and mixed ...

Diatoms and rotifers in cytological smears
Cytopathology, 2003We describe several uncommon contaminants presumably derived from the tap water used in the staining procedure of cytological specimens. We would like to draw attention to the occasional presence of diatoms and fragments of rotifers in cytological specimens.

Most of the data so far available concerning the occurrence of rotifers in Neusiedlersee result from observations made by Varga (1926, 1934) (see Chapter 22). The present author’s own investigations to be described in this chapter, have yielded considerable additional information on the faunistics and distribution of rotifers (Donner 1953, 1959, 1968 ...

Cost and speed of locomotion for rotifers
Oecologia, 1984The hypothesis that the ciliary locomotion of rotifers is size limited and that it accounts of a significant portion of the energy budget was investigated using the genera Brachionus and Asplanchna. Speed of movement was measured among clones of different size in Brachionus, which shows little size variation through development.

Distribution of rotifers in a Floridian saltwater beach, with a note on rotifer dispersal
Hydrobiologia, 1993Eighteen different rotifers were found at varying densities, depths and locations in the interstitial sand of a small, brackish-water Floridian beach. Most of the rotifers encountered were found in greatest numbers two meters from the waters edge, corresponding to the high-tide mark of the sampled beach.

Evolution of Rotifer Life Histories
Hydrobiologia, 2005When compared to most other multicellular animals, rotifers are all relatively small, short-lived and fast-reproducing organisms. However among and within different rotifer species there is a large variation in life history patterns. This review accounts for such variation in rotifers, with a strong focus on monogonont rotifers.
