Diatoms and rotifers in cytological smears

Cytopathology, 2003
We 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.

Cost and speed of locomotion for rotifers

Oecologia, 1984
The 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.

The Rotifers of Neusiedlersee

1979
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 ...

Distribution of rotifers in a Floridian saltwater beach, with a note on rotifer dispersal

Hydrobiologia, 1993
Eighteen 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, 2005
When 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.

Workshop on Culture Techniques of Rotifers

Hydrobiologia, 1980
Culture techniques of Rotifers can be considered of two types according to whether the number of associated species is known or not (Dougherty et al., 1960). The cases of monoxenic (one associated species), xenic (unknown number of associated species) and clonal cultures will be successively examined in the following.

Contributions to the knowledge of African rotifers: Rotifers from the Ivory Coast

Hydrobiologia, 1985
Two series of plankton samples, collected in different parts of the Ivory Coast, are examined for their rotifer content. Seventy-one taxa are identified to species level, some of which are present in different forms. Seventeen taxa are new to the Ivory Coast, three are new to Africa. Ecological and distributional notes are given.

Contributions to the knowledge of African Rotifers I. Rotifers from Senegal

Hydrobiologia, 1985
24 plankton samples, collected in different parts of the Republic of Senegal (W. Africa) were examined for their rotifer content. Seventy taxa were identified to species level, some of which were present in different forms. Thirty three taxa and forms are new to Senegal, three species are new to Africa.

Rotifer Ecology and Embryological Induction

Science, 1966
The rotifer Asplanchna releases into its environment a water-soluble, nondialyzable, pronase-sensitive factor which causes uncleaved eggs of another rotifer, Brachionus calyciflorus , to develop into individuals with a pair of long, movable spines which neither their mothers nor the ...
