Effects of secondary metabolites produced by different cyanobacterial populations on the freshwater zooplankters Brachionus calyciflorus and Daphnia pulex. [PDF]

open access: yesEnviron Sci Pollut Res Int, 2019
Cyanobacterial blooms in eutrophic water bodies are a worldwide problem. Combined effects of mixtures of secondary metabolites produced by different cyanobacterial species on aquatic fauna are still not well recognised.

THE USE OF LIVE FOOD IN REARING OF THE LARVAE OF GRASS CARP CTENOPHARYGODON IDELLA

open access: yesالمجلة العراقية للاستزراع المائي, 2022
The larvae of grass carp Ctenophargodon idella were fed on three types of live food Brachionus calyciflorus, Artemia sp. and Daphnia magna. The study showed that live food is very important to achieve high growth and survival of fish larvae.

Asymmetric Micro-Evolutionary Responses in a Warming World: Heat-Driven Adaptation Enhances Metal Tolerance in a Planktonic Rotifer, but Not Vice Versa. [PDF]

open access: yesGlob Chang Biol
Rapid genetic adaptation is a potentially important mechanism by which natural populations can increase their tolerance to human‐induced environmental stressors. In our study, we demonstrated that zooplankton populations adapted to heat stress exhibited increased tolerance to copper toxicity.

Ecotoxicological studies with the freshwater rotifer Brachionus calyciflorus

open access: yesEcotoxicology and Environmental Safety, 1993
The use of the freshwater rotifer Brachionus calyciflorus as a test organism for ecotoxicological studies was examined. Changes in the feeding-, swimming behavior- and demographic characteristics of the rotifers exposed to increasing concentrations of copper (Cu) were studied and the relationships between the different test parameters and their ...

Trade-offs between defense and competitive traits in a planktonic predator-prey system. [PDF]

open access: yesEcology
Abstract Predator–prey interactions are crucial components of populations and communities. Their dynamics depend on the covariation of traits of the interacting organisms, and there is increasing evidence that intraspecific trade‐off relationships between defense and competitive traits are important drivers of trophic interactions. However, quantifying

Population Characteristics of Brachionus calyciflorus and Their Potential Application for Evaluating River Health in the Pearl River Delta, China [PDF]

open access: goldWater, 2021
Water pollution can be monitored through the use of indicator species, including Brachionus calyciflorus. To do this, it is necessary to understand the species’ population ecology.

Variable Fitness Response of Two Rotifer Species Exposed to Microplastics Particles: The Role of Food Quantity and Quality

open access: yesToxics, 2021
Plastic pollution is an increasing environmental problem, but a comprehensive understanding of its effect in the environment is still missing. The wide variety of size, shape, and polymer composition of plastics impedes an adequate risk assessment.
