Abstract

A classical understanding of marine fishes is that they have high effective population sizes and high levels of dispersal due to an apparent lack of barriers in the marine environment. Therefore the realization of a genetic population structure is a slow process for marine organisms.

The aim of this project is to gain insights in the relationship between the neutral population structure and local adaptation in the marine environment by studying the interaction between selection, gene flow, population history and genetic drift. A non-commercial species, the sand goby (Pomatoschistus minutus), was chosen to distinguish between natural and anthropologically induced selection.

This project can provide a better understanding of how fish respond to the environment and by extension how they might respond to environmental change.
