A Perspective on Aging in Rotifers
Hydrobiologia, 1980Most research on aging in rotifers has been performed with populations, not with individuals. As a consequence, the dependent variable in these studies is usually either mean lifespan or rate of survivorship. After a brief consideration of the literature published since the last major review (King, 1969), the results of a series of experiments are ...

Psychiatry: Interpersonal and Biological Processes, 1967
Mary Gavell, Managing Editor of PSYCHIATRY since 1955, died of cancer on January 19, 1967. In publishing this story as a memorial to her, we could point out that many perceptive observers of human behavior consider the insights provided by the writers of fiction to be equal or superior to those of clinicians and scientists.

Diapause in Monogonont Rotifers
Hydrobiologia, 2005This review focuses on more recent findings on the diapause in Monogonont rotifers, since the major reviews by Pourriot & Snell (1983, Hydrobiologia 104: 213–224) and Gilbert (1992, Rotifera. In Adiyodi, K. G. & R. G. Adiyodi (eds), Reproductive Biology of Invertebrates, Vol. 5 – Sexual Differentiation and Behaviour. IBH Publishing Co., Oxford: 115–136;

Hydrobiologia, 1980
The sessile rotifers are taxonomically defined as all the individuals belonging to the families Flosculariidae, Conochilidae (Order Flosculariaceae), and Collothecidae (Order Collothecaceae) (Edmondson, 1940, 1944). Freeswimming species are, however, found in each family. The Conochilidae are totally planktonic.

Contribution to the study of african rotifers: rotifers from Mali
Hydrobiologia, 1992In samples collected from different parts of the Republic of Mali (W-Africa), ninety-two taxa of rotifers were identified. Some were present in different forms; 56% were cosmopolitan, 19% thermophilous with a wide distribution, 20% tropicopolitan and 5% cold-stenothermous. These latter species seem to be relicts of palaeoclimatic conditions in Africa.

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 ...
