摘要
In the present preliminary study, the authors identify 2 pathways through which invasive dreissenid mussels can transfer microcystin to higher trophic levels: either directly, through consumption by benthivorous fish such as the round goby; or indirectly, through their biodeposits, which are an important food source for benthic invertebrates. The results suggest that dreissenid mussels represent a potentially important benthic pathway for the food web transfer of microcystin. (c) 2013 SETAC
