After careful reflection between all the direct and indirect relationships in the Great Lakes, students have made some great inferences about the declining trout population. Maybe it was a decrease in a producer that caused the trout's population to fall. Or maybe it was a consumer it eats that got a disease?
But what if an invasive species, like the sea lamprey was introduced? Students are learning more about this invasive species which entered the Great Lakes waterways in the early 1900s. We're doing research to examine both the external and internal structures that would allow the sea lamprey to be so successful. We're also looking at the structures of bony fish, like the perch and trout to see why they maybe we're as successful in standing up to this invasive, and quite possibly, the cause of the trout's decline in the Great Lakes.
