- ... Reliable environmentally realistic bioassay methodologies are increasingly needed to assess the effects of environmental pollution. This study describes two estuarine sediment bioassays, one acute (96h) and one chronic (14d), with the New Zealand harpacticoid copepod Quinquelaophonte sp. utilising behavioural and reproductive endpoints. Spiked sediments were used to expose Quinquelaophonte sp. to ...

- ... Worldwide, estuaries are under increasing pressure from numerous contaminants. This study aimed to identify a suitable marine harpacticoid copepod species for toxicity testing of New Zealand estuaries. Multiple aspects were considered for species selection and included: a broad regional distribution, ease of culture, reproductive rate under laboratory conditions, sexual dimorphism, and sensitivity ...
