Federal department of Fisheries and Oceans Canada (DFO) members of the Cooperative Resource Management Institute

Douglas Braun
Research Biologist, DFO
Dr. Braun is an ecologist broadly interested in how environmental variation, from both natural and anthropogenic sources, shapes fish populations and their habitat. Specifically, his research focuses on: 1) how habitat variation within and among systems drives the dynamics and life-history of salmon populations, 2) how forest disturbance impacts stream ecosystems, and 3) developing tools that inform cost-effective monitoring of habitats and populations. He primarily work at the stream/population level and conducts applied habitat science using large-scale field studies.

Trevor Davies
Fisheries Stock Assessment Scientist, Ministry of Forests, Land, Natural Resource Operations & Rural Development
Adjunct Professor, REM, SFU
Dr. Trevor Davies is a Fisheries Stock Assessment Scientist with the British Columbia Ministry of Forests, Land, Natural Resource Operations & Rural Development. He has a diverse background in limnology, toxicology, fisheries resource evaluation & management and quantitative fisheries stock assessment. He in the principle investigator of the Keogh River Steelhead population dynamics project and sits on a number of student committee’s at SFU and UBC.

Emma Hodgson
Postdoctoral Fellow
Anthropogenic modifications of marine and freshwater environments result from a variety of human activities and have effects across social and ecological dimensions. My research focuses on the ways in which we can use and improve existing tools in ecology to advance our understanding and management of aquatic resources. These tools range across ecological scales, including: population modeling, ecosystem modeling and vulnerability & risk assessment.

My research as part of the Salmon Watersheds Lab will focus on the impacts of human activities in the Peel and Skeena river systems. In the Peel River (NWT), I will work with harvesters to improve our understanding of the ecology and migratory patterns of an important subsistence fishery species, Broad whitefish, Coregonus nasus, and its vulnerability to watershed change. In the Skeena watershed (BC), I will research estuarine use of different subsistence fishery species and risks to these critical resources.

Jeffrey Lemieux
Area Manager, North Coast, Ecosystems Management Branch, DFO
Jeffrey Lemieux has a science leadership role with Pacific Region Science Branch for the Department of Fisheries and Oceans. In that role, he leads Freshwater Science strategies and manages the Cultus Lake Salmon Research Laboratory, as well as staff stationed at SFU. Jeffrey's principal interests are improving the role of science in aquatic resource management, especially the consideration of landscape and regional contexts. He obtained his Ph.D. from Oregon State University in the fields of forestry and entomology, and gained his first experience working with salmon by analyzing insect components of salmonid diets in the nearshore juveniles of Barkley Sound.

Sean Naman
Postdoctoral Fellow
I am generally interested in better understanding how physical habitat structure (and human-driven changes to it) influences ecological processes across organizational scales (e.g., individuals, populations, and whole food webs). Much of my previous work has focused on relating stream channel structure and hydrology to the foraging, energetics, and growth of stream-rearing salmon. Some past projects include: (1) determining the influence of geomorphology and streamflow on salmon prey availability; (2) understanding constraints on productive capacity (i.e., the number of fish that a given stream can support); and (3) developing bioenergetics-based habitat suitability models for instream flow management.

My postdoctoral work with the salmon watersheds lab will expand on some of these general themes, but through a wider lens. Specifically, I will examine the cumulative effects of multiple anthropogenic stressors on watersheds supporting Pacific salmon.

David Patterson
Research Biologist, DFO
Adjunct Professor, REM, SFU
Mr. Patterson is the head of the Fraser River Environmental Watch Program, which monitors and forecasts Fraser River water conditions and researches the impact of environmental conditions on migratory and reproductive success of adult sockeye salmon. Science advice is provided to fisheries managers to assist in the prediction of en-route loss and pre-spawning mortalities associated with adverse river conditions


Daniel Selbie
Head, Lakes Research Program, Ecosystem Sciences Division, DFO
Adjunct Professor, REM, SFU
Dr. Selbie is a limnologist and aquatic ecologist, whose research principally targets the freshwater life history of Pacific salmon, and the structure, functioning, and productive capacity of their natal ecosystems.  Dr. Selbie’s research group, graduate students, and post-doctoral fellows integrate limnology, paleolimnology, fisheries science and environmental science, through field surveys, targeted experiments, and modeling to understand the effects and interactions of natural and anthropogenic forcings on Pacific salmon production and nursery ecosystem dynamics.
