Interspecific Relationships between Coexisting Micro-organisms in the Freshwater Rotifer (Brachionus calyciflorus) Culture Tanks as Microcosm

Monogonont Rotifer, Brachionus calyciflorus, Possesses Exceptionally Large, Fragmented Mitogenome

In contrast to the highly conserved mitogenomic structure and organisation in most animals (including rotifers), the two previously sequenced monogonont rotifer mitogenomes were fragmented into two chromosomes similar in size, each of which possessed one major non-coding region (mNCR) of about 4-5 Kbp. To further explore this phenomenon, we have sequenced and analysed the mitogenome of one of t...

Evaluation of Yeast Saccharomyces cerevisiae and Algae Chlorella vulgaris as Diet for Rotifer Brachionus calyciflorus

A study was conducted to evaluate the effect of yeast Saccharomyces cerevisiae and algae Chlorella vulgaris on the production of rotifer Brachionus calyciflorus. The Brachionus calyciflorus were cultured using four different types of diets: fresh Chlorella vulgaris (T1), yeast with fresh Chlorella vulgaris (T2), powder Chlorella vulgaris with fresh Chlorella vulgaris (T3) and yeast with powder ...

Biochemical nutrient requirements of the rotifer Brachionus calyciflorus : co-limitation by sterols and amino acids

1. It has been proposed that growth and reproduction of animals is frequently limited by multiple nutrients simultaneously. To improve our understanding of the consequences of multiple nutrient limitations (i .e. co-limitation) for the performance of animals, we conducted standardized popUlation growth experiments using an important aquatic consumer, the rotifer Brachionus calyciflorus. 2. We c...

Effect of Permethrin insecticide and Paraquat herbicide on growth and population density of freshwater Rotifer (Brachionus calyciflorus)

This study evaluated the acute toxicity of herbicide paraquat and the insecticide permethrin and their impacts on growth and reproduction of freshwater rotifers Brachionus calyciflorus according to the guidelines OECD. The acute toxicity (LC50 24h) of paraquat and permethrin on freshwater rotifers B. calyciflorus were 0.541 and 8.997 mg l-1, respectively. The level of exposure responses of roti...
