| Impact Description | After P. phoxinus invaded an alpine lake that only contained Brown Trout, the abundance of the cestode Diphyllobothrium ditremum increased dramatically. As Phoxinus phoxinus are prey for various birds, the fish invasion increased the presence of birds in the lake, which are the final hosts for Diphyllobothrium ditremum. Therefore, a higher abundance of birds increased the output of Diphyllobothrium ditremum eggs into the lake resulting in higher infection rates in Brown Trout which had negative health impacts |
