Abstract Four New Zealand cladoceran species (Daphnia carinata, Simocephalus vetulus,
Ceriodaphnia dubia, and Ceriodaphnia cf. pulchella) were compared with Daphnia magna …

Forty‐eight‐hour acute toxicity tests were performed to determine the influence of
acclimation temperature (5, 15, and 20° C) and exposure temperature (5, 15, and 20° C) on …

The primary objective of the 48-hour toxicity test using Daphnia sp. is to evaluate the acute
toxicity of effluents, chemicals, and elutriates on freshwater crustaceans (in particular …

The effects of physicochemical conditions, such as pH, water hardness, flow rates and
natural organic substances on the sensitivity of Ceriodaphnia dubia to the toxic effects of …

Seven‐day tests with Ceriodaphnia dubia are commonly used to estimate toxicity of effluents
or receiving waters but can sometimes yield no toxicity outcomes even if pollutants are …

Cladocerans and copepods are common inhabitants of ponds and lakes, but assessments
of the toxic effects of chemicals on aquatic organisms are often based mainly on toxicity data …

Caloric content is a reliable biomaker of effect since it is modified by exposure to toxicants
that can alter basal metabolism. Since organisms' age modifies how energy resources are …

Previous research done on the effects of contaminant mixtures has been evaluated primarily
by using acute exposures. While this was an important initial step, characterizing the effects …

Acute and chronic bioassays were conducted to determine the effects of copper, lead, and
zinc mixtures on Ceriodaphnia dubia and Daphnia carinata. Copper, lead, and zinc …

The speciation and bioavailability of metals are known to be affected by pH. Although many
studies have focused on effects on metals of pH changes resulting from lake acidification (ie …
