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.

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;

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.

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 ...

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.

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 ...

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.

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.

The dataset of known rotifer records in Italy was built based on 330 published papers, spanning the period from 1838 to 2022. The dataset includes 15,506 occurrence records, 11,996 of which with georeferenced coordinates. A total of 12,658 records belong to 584 taxa at valid species and subspecies level, 697 records belong to 18 species groups, 1755 ...
