The importance of 'edge populations' to biodiversity
18 / 12 / 2018, Eureka Alert
More than two-thirds of Canada's biodiversity is made up of species that occur within the country's borders only at the very northern edge of their range. Biologists have long debated how much effort should be dedicated to conserving these 'edge populations.' One argument in their favor is that they may be especially well suited to lead northward range shifts for their species as the climate warms.
