Studies of natural selection and sexual selection in an unusual tropical land fish

My Masters of Philosophy thesis investigated the influence of selection on an animal invading a novel habitat, and how subsequent differences in natural selection, sexual selection and genetic drift might influence phenotypic variation among populations. The Pacific leaping blenny on Guam (Alticus arnoldorum) provided a novel opportunity to address these aims as it has made one of the most extreme ecological transitions possible, it is a fish that lives its entire adult life on land.
