Abstract: <p>Fisheries assessment and management approaches have historically focused on individual species over relatively short timeframes. These approaches are being improved upon by considering the potential effects of both broader ecological and evolutionary processes. However, only recently has the question been raised of how ecological and evolutionary processes might interact to further… more Full Text: ECO-EVOLUTIONARY DYNAMICS IN A COMMERCIALLY EXPLOITED FRESHWATER FISH A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Faculty of Arts and Science TRENT …

Abstract: <p>Since its introduction to North America in the 1990s, the Round Goby has spread throughout the Great Lakes, inland through rivers and is now moving into small tributary streams, a new environment for this species in both its native and invaded ranges. I explored density and temporal occupation of Round Gobies in four small streams in two systems in south-central Ontario, Canada in order… more Full Text: TEMPORO-SPATIAL PATTERNS OF OCCUPATION AND DENSITY BY AN INVASIVE FISH IN STREAMS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and …

Abstract: <p>Contemporary evolution has the potential to help limit the biological impact of rapidly changing climates, however it remains unclear whether wild populations can respond quickly enough for such adaptations to be effective. In this thesis, I used the introduction of native North American Pumpkinseed (Lepomis gibbosus) into the milder climate of Europe over 140 years ago, as a '… more Full Text: CONTEMPORARY ADAPTIVE SHIFTS IN THE PHYSIOLOGY AND LIFE HISTORY OF PUMPKINSEED (LEPOMIS GIBBOSUS) INTRODUCED INTO A WARM CLIMATE.
