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.

2022
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 ...

Rotifer Ecology and Embryological Induction
Science, 1966The 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 ...

Contributions to the knowledge of African Rotifers I. Rotifers from Senegal
Hydrobiologia, 198524 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.
