    Professor, Canada Research Chair in Marine Renewable Resources (2006-2016)

    My research is shaped by a strong interest in past, present and potential future human impacts on marine species and ecosystems. Human activities such as fishing and hunting, habitat alteration, and nutrient loading have influenced marine ecosystems for millennia, but strongly accelerated over time and expanded from the coasts to the open ocean. My work aims to reconstruct the long-term history of human-induced changes and understand their causes and consequences for the structure and functioning of marine ecosystems today and in the future.

      Visiting Researcher, PhD

      I am interested in the impacts of coastal resource use on marine ecosystems in the past, present and future. Currently, I am a post-doctoral fellow in the NEREUS Program at the University of British Columbia, but remain affiliated with the Lotze Lab at Dalhousie. In general, I use ecosystem models to understand the impacts of fisheries and other human impacts as well as their management on  marine species, communities and ecosystems. I am also the regional coordinator of the FISH-MIP project, which aims to understand the impacts of climate change on marine ecosystems and fisheries, and a science committee member of the Oceans Past Initiative, which aims to extend historical baselines to better understand human impacts on marine ecosystems. Finally, I am also a visiting scientist at the Charles Darwin Foundation, Galápagos Islands, where I participate in ecological monitoring and fisheries modelling of the endemic grouper to inform conservation and management.

        Coastal ecosystems are among the most productive and most impacted by anthropogenic activities in the world due to current and past human pressures. My research interests focus on the effects of various human stressors on the structure and services of seagrass and macroalgal dominated ecosystems. Along with salt marshes and mangroves, they can be found in coastal waters around the world can rival terrestrial biomes in their provision of essential ecosystem services. Understanding their contribution and how it may be altered by human activities is essential for the proper management and conservation.

          Major biological changes in marine ecosystems have been associated with a changing climate both in the past and into the future. These changes have significant consequences for marine ecosystem structures and functioning, associated ecosystem services, and marine conservation measures. How these changes may play out on regional or ocean-basin scale is still largely unknown. My research addresses expected future changes in ecosystem dynamics and marine fisheries in the North Atlantic Ocean using meta-analytical techniques, spatio-temporal trend analysis, and mapping approaches. In this context implications for marine management and conservation on regional and trans-Atlantic scales will be identified in order to inform the development of effective management and adaptation policies.

            Fisheries are vital ecosystem services, and their productivity may be linked to habitat quality and availability. Many fish species use vegetated habitats as nurseries, which has important consequences for habitat protection and fisheries management. My work addresses the role vegetated coastal habitats play in supporting juvenile fish and commercial fisheries in the past and present, using both a large-scale spatial and long-term temporal approach. This may have implications for how fisheries are managed in Atlantic Canada, due to recent changes in the Fisheries Act which altered the definition of fish habitat.

              I am interested in the effects of global change on the base of oceanic food-webs: the phytoplankton communities. Phytoplankton is responsible for half of the world’s primary production and is of a major importance for sustaining fish stocks. In my work I use both experimental and modelling approaches to analyze the role of phytoplankton for the resilience of marine food webs in the changing ocean.

                Seagrass beds are among the most productive ecosystems on the planet and the most diverse of all the soft-bottom marine communities. However, anthropogenic impacts such as nutrient loading and eutrophication have led to seagrass declines worldwide and continue to threaten these highly diverse habitats. My work aims to quantify regional variation in infaunal communities of eelgrass habitats in Atlantic Canada and investigate changes in community structure in relation to environmental factors, nutrient loading, and finfish aquaculture.

                  Global sea surface temperature (SST) has been increasing as a result of climate change. Along the rocky shores of the Northwest (NW) Atlantic, macroalgae are the dominant habitat-forming species, providing many ecological services, as well as being of commercial importance. Because they are strongly influenced by water temperature, their distribution will likely be affected by increasing SST. My work examines the impact of climate change, particularly increasing SST, on the distribution of common, habitat-forming macroalgae along the rocky shores of the NW Atlantic. I combine bioclimate envelope models with physiological thresholds to predict future distribution shifts under different climate change scenarios.

                    Groundfish communities on the Scotian Shelf have experienced periods of intense fishing pressure by foreign and domestic fleets. Several areas are now permanently or seasonally closed to fishing in order to facilitate the recoveries of key species. My honours project examines changes in groundfish biomass, abundance and community structure. By examining the differences before and after fisheries closures, as well as between closed and non-closed areas, the success of fisheries closures can be evaluated. This may assist with planning of future closed and protected areas.

                      Lab Manager & Scientific Coordinator of TOSST (Transatlantic Ocean System Science and Technology)

                      I have a Master of Marine Management (MMM) degree through the Marine Affairs Program at Dalhousie University, previous degrees in Fisheries Management and Spanish/Criminal Justice. I am currently coordinating NSERCs Collaborative Research and Training Experience (CREATE) for Transatlantic Ocean System Science & Technology (TOSST) at Dalhousie University. I have a strong attraction to marine conservation, yet my predominant area of interest lies in elasmobranch conservation; specifically, looking at how stakeholder input and community involvement can further advance conservation efforts.
