Jean Polfus is a Liber Ero Postdoctoral Fellow. She recently completed her PhD at the University of Manitoba conducting genetic and traditional knowledge studies on caribou populations in partnership with the Ɂehdzo Got’ı̨nę Gots’ę́ Nákedı (Sahtú Renewable Resources Board) and five Ɂehdzo Got’ı̨nę (Renewable Resources Council) in the Sahtú Region, Northwest Territories, Canada. Her project built a comprehensive understanding of the identities and relationships among caribou populations and Dene people in order to inform and prioritize management efforts. She is committed to an approach to conservation that respects the lives and experiences of people that depend on natural resources for their livelihood, facilitates cooperative long-term problem solving, improves the performance of ongoing research, and affirms the value of community caribou stewardship.

There may be a type of caribou that science never noticed
In the Sahtú region of Canada, science has identified three distinct groups of caribou – but the local people believe there is a secret fourth caribou.
How to Name a Caribou
Last Word on Nothing online
Few species are more frustrating to taxonomists than the North American caribou. Ranging from the Canadian Arctic to the Great Lakes, caribou vary enormously in size, color, antler shape, habitat, and behavior. For more than two centuries, scientists have argued over the identities and distributions of caribou subspecies and populations, and while they now generally agree on the existence of four North American subspecies, naming criteria remains controversial and, in some places, wildly inconsistent.

What indigenous communities are teaching scientists about nature
In the rugged Sahtú region of Canada’s Northwest Territories, a district so remote that in winter only a single treacherous ice road connects it to the outside world, life revolves around caribou. For millennia, the Dene people lived as nomads, tracking vast herds across the Sahtú and harvesting the itinerant animals for their meat, skin, and bones.

The Northern Living Series: Jean Polfus // Tulı́t'a, Northwest Territories
Wild Fir Tree online
In our forth interview for the Northern Living Series we hear from Jean Polfus, a postdoctoral fellow, who studies caribou while living in Tulı́t'a, Northwest Territories along with her husband Joe and their newborn son Tristan. Here she shares her experience of living in a small, fly-in community in the heart of Canada's true north, touching on life with 3 hours of daylight, northern childbirth, and Dene celebrations...
