Maturation reaction norm evolution in smallmouth bass populations

We constructed an individual-based model to investigate the divergence of two smallmouth bass (Micropterus dolomieu) populations. Smallmouth bass are economically important sport fish that inhabit freshwater lakes in many parts of the world. The two study populations, from Algonquin Provincial Park Canada, were introduced in the early 1900’s from the same source. Studies show that although the populations had the same source, today they differ substantially in growth and maturation. We are using our simulation model to determine if differences in adult mortality and predation could have contributed to an evolutionary divergence in the maturation reaction norms of these populations.
