Dr. Devito is a participant in the Land Reclamation International Graduate School (LRIGS) program sponsored by NSERC CREATE.
Landscape eco-hydrology, forest and wetland hydrology and biogeochemistry, ground-surface water interactions, land use and climate impacts, hydrogeology frameworks, influence of climate and geology on the susceptibility of boreal ecosystems to disturbance, watershed management.
The long-term objective of my research is to increase our understanding and model the interaction of climate, geology and landscape position on boreal forest- wetland-aquatic ecosystem and predict their susceptibility to land use changes. This research has provided a fundamental understanding of how water, and chemistry of interest, moves through the surrounding boreal environment, how land use activities may intersect or impact water movements, and how boreal ecosystems recover from land use or reclamation activities.
Current Research Interests
My current research focuses on the Utikuma Region Study Area (URSA), located on the Boreal Plain, Alberta. At URSA, my students and I have collaborated in a number of long term (>10 years) studies investigating trends in regional climate and hydrogeology in conjunction with local scale eco-hydrologic studies of forest-wetland-aquatic systems located on a variety of landforms and landscape positions representative of the Boreal Plain. These systems also serve as natural analogues for designing, and benchmarks for evaluating, reclamation strategies on oil sands mining leases. My Students, collaborators and I are also involved in parallel and complimentary studies looking at the influence of landform configuration on the development of wetland and forest ecosystems in constructed watersheds in the Oil Sands near Fort McMurray. I am participating in 4 related research areas:
1) Impact of large-scale disturbance (wildfire, forest harvest) on landscape hydrologic connectivity and boreal ecosystem processes.
2) Distribution and processes maintaining perched / isolated peatland wetlands in sub-humid Boreal Landscapes.
3) Classifying the role of riparian transitions in different landscapes of the Western Boreal Forest.
4) Effective design criteria to sustain forest and wetland ecosystems on constructed watersheds, Oil Sands, Fort McMurray.

BIOL 333 - Wetland Science and Management
The course includes an introduction to the hydrology, biogeochemistry and ecology of wetland ecosystems. Topics covered include classification, geomorphic setting, distribution, functions and ecosystem services of wetlands. Human use, alteration and management of wetlands are examined. An emphasis is placed on wetlands and wetland management in Western Canada, including boreal peatlands and prairie marshes. A full day field trip on a Saturday is required. Prerequisite: one of BIOL 208, REN R 250, or EAS 201. Credit may be obtained in only one of BIOL 333 and REN R 333. This course requires payment of additional student instructional support fees. Refer to the Tuition and Fees page in the University Regulations section of the Calendar.
