Scientific Objectives

Our over-arching goal is to understand and predict the response of marine ecosystems to environmental change. The group is highly multi-disciplinary with expertise in different of fields of marine biogeochemistry (e.g., trace metals, paleoclimates, carbon chemistry) and the ecology and biodiversity of organisms ranging from viruses to metazoans. Cutting across traditional research domains is essential to study the response of marine ecosystems to environmental change because the changes involve phenomena that are at once physical, chemical, and biological and occurring on various scales of time and space.

Our research activities fall within two broad categories or themes: (1) Biodiversity and biological interactions (2) Biological responses to environmental change, from organisms to ecosystems

RESEARCH THEMES

1) Biodiversity and Biological Interactions

Small marine organisms, planktonic or benthic, are particularly well-suited for testing hypotheses related to biodiversity. They include a very wide taxonomic range of both unicellular and multi-cellular forms whose small sizes and short generation times facilitate experimentation. The particular groups studied are quite diverse (viruses, bacteria, tintinnids dinoflagellates, copepods and mieofaune) reflecting the expertise and interests of individual researchers. The originality of our research in biodiversity is the integration of a variety of abiotic and biological interactions (competition, predation, parasitism). Our goal is quantify the relative importance of these interactions in the maintenance of, and changes in, biodiversity in marine systems.

 

2) Biological responses to environmental change, from organisms to ecosystems

 We study the mechanisms and impacts of environmental changes on different spatial and temporal scales. These range from global, historical and long-term changes such as ocean acidification, warming and expansion of low oxygen zones to regional scales influenced by large scale nutrient, trace metal and contaminant inputs down to regional areas impacted by urbanization or introduced species. Our research concerns both pelagic and benthic ecosystems and involves a wide range of approaches from laboratory and in situ experimentation to isotope analysis. Our topics span scales of time and from the recent changes in ocean acidification to the mass extinction of the Phanerozoic.
