EFFECTS OF TEST DESIGN AND TEMPERATURE IN A PARTIAL LIFE-CYCLE STUDY WITH THE FRESHWATER GASTROPOD POTAMOPYRGUS ANTIPODARUM

摘要

Potamopyrgus antipodarum is a candidate for a standardized mollusk partial life-cycle study. This is a comparative study of two test designs (microplate and beaker), with additional endpoints to the proposed guideline methods, for example, tracking of continuous reproductive output over 28 d and attributing it to individual female snails. In addition, an investigation of the effects of temperature (16, 20, and 25℃) on reproduction was also conducted employing the microplate design.
