Physical Ecology is the interdisciplinary examination of evolutionary and ecological phenomena across taxa, populations, communities and ecosystems within a physical perspective.  In our laboratory it involves the examination of the biology and ecology of aquatic organisms within their fluid environment, which is why we apply both ecological and hydrodynamic theories, models, and ideas in our research. 

The ecological and evolutionary questions that underlie our research interests include the  manner by which organisms have adapted to their physical environment, physical aspects of energy transfer through ecosystems, physical-biological linkages in aquatic ecosystems, and the convergent evolution of morphology. We have been fortunate to ask many of these questions within an applied context related to Species at Risk/conservation, industrial ecology, fisheries, and forestry, management. 

We are currently examining the physical ecology of: (1) trophic interactions including photosynthesis and suspension feeding, (2) reproduction including abiotic pollination and broadcast spawning; and (3) aquatic sciences including sediment/substrate-water interactions.  Our lab is actively involved in species and ecosystem recovery in southwestern Ontario involving unionid mussels, and hypoxia issues in the Great Lakes and their watersheds.

Please contact Dr. Joe Ackerman if you are interested in joining the lab.
