The study investigates the relationship between changes in physiological energetics of
organisms and alterations of growth, development and reproduction of Daphnia magna …

This work tested the hypothesis that animals with a high energy status are more successful
in dealing with stress than animals with a low energy status. Daphnids (Daphnia magna) …

Background, aim, and scope Climate changes are nowadays an important issue of concern,
and it is expected that in the near future it will be intensified, leading to extreme …

Survival, number of neonates per female, first day of reproduction and neonate size were
investigated in Daphnia magna, exposed to cadmium concentrations ranging from 0 to 50.0 …

Daphnids were reared for 2 weeks in different concentrations of food or cadmium, and
growth and reproduction were measured as endpoints. At the end of the 14-day …

Abstract The Cellular Energy Allocation (CEA) methodology wasdeveloped as biomarker
technique to assess the effectof toxic stress on the energy budget of testorganisms. This …

In nature, organisms have to respond to a diversity of factors acting simultaneously. The
present investigation was conducted to study whether changes in food (Chlorella) levels …

Ten substances were tested to compare two methods that can be used in chronic toxicity
studies with the Cladoceran Daphnia magna. In semistatic experiments with cohorts (life …

Daphnids were chronically exposed to waterborne Am-241, an alpha-emitting radionuclide,
ranging in concentration from 0.4 to 40Bqml− 1. Am-241 amounts were monitored in the …

Two prevailing theoretical models: concentration addition (CA) and independent action (IA),
predict mixture toxicity on the basis of known toxicities of the mixture components. To date …
