Abstract

This report provides the results of a statistical analysis of an experiment with Marisa cornu-arietis (Prosobranchia), the subtropical Ramshorn snail, which was performed during the EU Project “Comprendo”. This project aimed at studying the possible impact of endocrine dis-rupters mainly on invertebrate species. Exposure experiments with Bisphenol A (BPA) were performed as semistatic renewal systems under food surplus.
