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...

As the primary consumers in aquatic organisms, zooplankton play an important role ecosystems. It is valuable for management and researchers to have insight into responses of community patterns environmental factors. In this study, RDA variation partitioning analysis were adopted determine factors affecting abundance biomass, as well relative importance different The findings reveal that TN (tot...

Salinity is an important variable influencing the density and diversity of rotifers. Studies on salt tolerance of rotifers have so far concentrated on euryhaline species while very little information is available on non-euryhaline taxa. In the present work, we have evaluated the combined effects of Chlorella vulgaris and sodium chloride on the population growth of two freshwater rotifers B. cal...

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...

Abstract The widespread use of the nanomaterials increases emission nano-pollutants into water. Carbon are particularly interesting. They characterized by relatively stable structure, which makes them able to migrate and accumulate in environment. Therefore, aim this study was determine potential toxicity at different trophic levels four selected carbon nanostructures: graphene oxide (GO), redu...
