Using primarily DNA-based tools, my research is aimed at the elucidation of fundamental aspects of a species' biology such as patterns of dispersal and gene flow, evolution of life histories and behaviour, response to environmental stress, and mechanisms of speciation, as well as the application of molecular tools to the management and conservation of exploited aquatic species from temperate, tropical and Antarctic marine and freshwater ecosystems.

Research includes the molecular analysis of population and species biodiversity of aquatic animals, with studies aimed at understanding the forces that shape genetic structure in the wild, and how such structure may influence adaptation, population persistence and distribution. Notable areas of activity include: the evolution and ecological significance of population differentiation, phylogeography and phylogenetics of aquatic taxa, the molecular analysis of past populations using PCR-based recovery of DNA (ancient DNA) from resting eggs and preserved material (e.g. fish otoliths and scales), DNA barcoding, traceability of fish and fish products, the evolutionary genetics of clonal animals, the evolution of adaptive traits using molecular, genomic and quantitative genetic analysis, and fisheries and conservation genetics of exploited fish in temperate, tropical and Antarctic waters.

Recent significant investment in the discovery of single nucleotide polymorphisms (SNPs), especially in exploited marine fishes provide new approaches to tackling structuring in the marine environment and the identification of candidate genes.

The Bangor-based Molecular Ecology and Fisheries Genetics Laboratory (MEFGL) that I continue to coordinate now represents among the largest European groupings focusing on the molecular ecology and evolution of aquatic taxa, which in 2013 will be extended further with the appointment of two new lecturers. Martin Taylor, who was a founder member of the MEFGL since 2005, on 1 January 2013 took up a new post as Senior Lecturer in Molecular Ecology at the University of East Anglia ( The two new lecturers are: Dr Mark de Bruyn who has been based in MEFGL since his Marie-Curie Fellowship in 2009, will start on 1 May 2013, and Dr Michael Knapp, Research Fellow in the Allan Wilson Centre for Molecular Ecology and Evolution Department of Anatomy University of Otago, who will start in Bangor on 1 April 2013. The new appointments signal a significant expansion in the strength and scope of research and training activities of the MEFGL, especially in the area of ancient DNA to explore the impacts of long-term environmental change on biodiversity, and to reveal novel insights into the demographic history of extinct species, especially birds and mammals.
