Research Line: Ecology of Marine Rocky Shores

     

     


My lab investigates the ecology of marine rocky shores, focusing on invertebrates and seaweeds at the population and community levels.  Using species and habitats from northern Atlantic shores, my goals are to understand the biological and environmental factors affecting these systems and to develop ecological theory in general.  Examples of current and recent projects are:

- Environmental stress models of species richness and functional-group diversity
- Potential effects of ocean warming and acidification on benthic invertebrates
- Non-consumptive effects of predators on prey
- Productive capacity of coastal breakwaters
- Biogeography of an intertidal predator-prey system
- Pelagic food supply and regional barnacle recruitment
- Epiphyte-host interactions in macroalgal beds
 - Influence of sea ice on intertidal organisms
- Population dynamics of clonal and unitary seaweeds
- Abundance of life-history phases in red algae

I particularly like to guide STUDENTS in research projects.
