Summary Introduction
To review:
The introduction of the zebra mussel into the great lakes that has a significant impact on the lake ecosystem.
Introduction:
There are some invasive species in our environment, which are introduced into the ecosystem that might overtake or dominate the native species. One such example is the zebra mussel, which was introduced in the Great Lakes by oceangoing vessels.

Data points represent shell lengths of the ten largest individuals found in the patch on each sampling date. Dashed lines to the x- axis indicate estimated times of settlement and initial growth in the patch. Arrows on the growth curves indicate the smallest size at which each species may reach sexual maturity. The blue mussel appears to reach a maximum shell length, suggesting that they were outcompeted by California mussels. The California mussel colonizes the patch later but within a few months have grown to a larger size than blue mussels. The two species colonize the patch…arrow_forward
