Wolves, bison and the dynamics related to the Peace-Athabasca Delta in Canada's Wood Buffalo National Park
Canadian Circumpolar Institute, 1993 - Nature - 270 pages
This study presents the hypothesis that the physical changes in the Peace-Athabasca Delta in northern Alberta (resulting from damming of the Peace River upstream), have favoured the wolf populations in Wood Buffalo National Park at the expense of bison (both plains and wood bison), and that there is urgent need to reverse the hydrological regime.
