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...
متن کاملBioaccumulation of atrazine: effects on population growth and reproduction of the rotifer Brachionus calyciflorus fed atrazine-exposed microalgae
Little information is known about bioaccumulation of atrazine or the effects it has on consumers that ingest atrazine-contaminated prey. For that reason, freshwater microalgae Chlorella vulgaris cultures were exposed to different concentrations of atrazine for twenty-four hours and were then used as an exclusive food source for Brachionus calyciflorus for three days with the intent to evaluate ...

15 صفحه اولMonogonont 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...
