A fundamental goal of evolutionary and conservation biology is to elucidate the mechanisms linking genotype to fitness. This is not only essential for understanding microevolutionary processes but also has a bearing on important problems facing society, such as global climate change. To tackle this question, we use a combination of classical population genetic approaches and cutting-edge genomic methods to study wild populations. Our research is producing increasingly powerful insights into the genetic basis of fitness variation.
Much of our work is based on long-term studies of wild populations such as fur seals breeding in the sub-Antarctic. These systems provide a wealth of individual-based data that can be linked to genotype. For instance, we recently used detailed genetic, life-history and environmental data to show that climate change is selecting for increased genetic diversity in a declining fur seal population. Building upon the theme of climate change, we are also combining genomic data with geographical, time series and experimental approaches to explore the genetic basis of adaptation to environmental change, using marine invertebrates as model systems.
