The protonephridial systems of a number of metazoa consist, in part, of flame cells or flame bulbs which are specialized structures attached to paired collecting tubules. In rotifers, each tubule is said to bear two to eight (1) or more (2) flame bulbs. These structures are located in the pseu-docoelomic cavity and are believed to function in the control of osmotic pressure and, possibly, in th...

Abstract The holobiont concept places emphasis on the strict relationship between a host and its associated microbiome, with several studies supporting strong effect of quality microbiome fitness. generalities have been questioned for invertebrates, including zooplankton. Here we assess role ecology, habitat, evolutionary history to explain differences in microbiomes rotifers, across broad taxo...

Algal biofuels are investigated as a promising alternative to petroleum fuel sources to satisfy transportation demand. Despite the high growth rate of algae, predation by rotifers, ciliates, golden algae, and other predators will cause an algae in open ponds to crash. In this study, Chlorella kessleri was used as a model alga and the freshwater rotifer, Brachionus calyciflorus, as a model preda...

Fernandez-Reiriz, M.J., Labarta, U. and Ferreiro, M.J., 1993. Effects of commercial enrichment diets on the nutritional value of the rotifer (Brachionus plicatilis). Aquaculture. 112: 195-206. The rotifer, Brachionus plicatilis, pre-fed on baker’s yeast, was enriched for 6 h with three commercial products from Artemia Systems S.A., namely Protein Selco (microcapsules), Dry Selco (microparticles...

During the spring clear-water phase of 1993, an enclosure experiment was performed in the mesotrophic Schohsee (Plon, FRG) in order to assess the impact of crustacean zooplankton on the rotifer and phytoplankton community. Among the crustacean plankton, calanoid and cyclopoid copepods were abundant, but Daphnia 'longispina' reached the highest densities in this experiment. The colonial rotifer ...

feeding behavior of yellowfin seabream larvae during the first two weeks of larval life was studied by feeding larvae  on different ratios of live food and  microencapsulated diet (med). food consumption rate increased progressively with increasing larval weight. the results from visual observation of the larval guts under a light microscope indicated that yellowfin seabream larvae were able to...

The bdelloid rotifer Adineta ricciae is an asexual microinvertebrate that can survive desiccation by entering an ametabolic state known as anhydrobiosis. Two late embryogenesis abundant (LEA) proteins, ArLEA1A and ArLEA1B, have been hypothesized to contribute to desiccation tolerance in these organisms, since in vitro assays suggest that ArLEA1A and ArLEA1B stabilize desiccation-sensitive prote...

Abstract Zooplankton is a good indicator of water quality state. Analysing the species composition and abundance, it possible to assess condition body predict direction changes. The aim study was analyse zooplankton in shallow urban lake, which restoration limited one method, i.e. wind-aeration. results were compared with earlier data obtained during sustainable (three methods: wind-aeration, p...
