Diet quality impact on growth, reproduction and digestive activity in Brachionus calyciflorus
We examined population growth rate, reproduction and phosphatase activity in digestive tracts of individual Brachionus calyciflorus fed by P-replete (molar C:P 1⁄4 107) or P-depleted (C:P 1⁄4 920) algal food supplied at three carbon (C) concentrations (1, 2, and 4 mg C L). Rotifer growth rate was significantly influenced by P content, whereas the effect of algal C concentration was not signific...
متن کاملEvaluation 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 ...
متن کاملMonogonont 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...
متن کاملMaternal age and spine development in a rotifer: ecological implications and evolution.
Brachionus calyciflorus typically develops long, defensive spines only in response to a kairomone from the predatory rotifer, Asplanchna. However, in the absence of any environmental induction, females of some clones produce daughters with increasingly long spines as they age; late-born individuals can have posterolateral spines as long as those induced by Asplanchna: up to 50% or more of body ...
متن کاملEffect of different densities of live and dead Chlorella vulgaris on the population growth of rotifers Brachionus calyciflorus and Brachionus patulus (Rotifera).
In order to maintain rotifer populations during periods of low algal production, it is necessary to offer alternate diets, some of which include forms of preserved algae. The present work is based on the effect of live and dead Chlorella vulgaris on the population growth of Brachionus calyciflorus and Brachionus patulus. The experimental design consisted of three algal levels (0.5 x 10(6), 1.5 ...
