I have published over 370 peer review papers and book chapters. I have worked on lampreys throughout my academic career. Lampreys are an important group of vertebrates for the following reasons. 1) As they are one of the two surviving groups of jawless fishes, and thus represent an early offshoot of the vertebrate lineage, they are frequently used for elucidating trends exhibited during early vertebrate evolution. 2) They are one of the most numerous vertebrates in many rivers in temperate regions of the Northern and Southern Hemispheres and thus play a key role in the ecology of those systems. 3) The adult parasitic phase in the life cycle of certain species has also been responsible for massive mortalities among important recreational and commercial fish species. My work on lampreys has involved studies of the taxonomy and evolution of this group and has focused in particular on the taxa found in the Southern Hemisphere, about which little was known prior to my PhD. I have also collaborated with a number of colleagues on ecological, physiological and biochemical studies on lampreys. The results of the ecological studies have led to a greater understanding of the duration of life, growth and behaviour of the different phases in the life cycles of a number of species. The second main area of my research has concentrated on working with numerous staff and research students in studies aimed at determining the biological characteristics of a wide range of fish species. As a number of these species are of commercial and/or recreational importance, the results of these studies have provided fisheries and environmental managers with the types of data they require for managing and conserving natural resources. These studies have also been aimed at exploring a number of contemporary theories, such as the Metabolic Theory of Ecology. The third area of research has involved work on estuaries in both the Northern and Southern Hemispheres. The results of these studies has increased our understanding of the factors that influence the density, diversity and compositions of particularly of the fish faunas in these systems and have emphasised the role of estuary type, e.g. permanently vs seasonally-open and normally closed, on those characteristics. Recently, together with a number of colleagues, emphasis has been placed on examining the impact of anthropogenic changes on faunal communities in estuaries.
