Parallelism in ecological speciation of Threespine Stickleback (Gasterosteus aculeatus)
I am interested in the predictability of the evolution of new species (speciation) through natural selection. A great way to explore this question is through the use of naturally-replicated, parallel divergences, such as those found in populations of threespine stickleback (Gasterosteus aculeatus) on Vancouver Island. In multiple, independent watersheds, this species has split into two very different ecomorphs: a more benthic stream form, and a more limnetic lake form. By studying the degree to which the replicate populations have followed the same evolutionary path, I hope to better characterize determinism in natural selection and speciation.
