Figure 5. The Qamanirjuaq, Bathurst and George River subpopulations experience varying levels of population growth during the eruption periods of their respective cycles. The Qamanirjuaq subpopulation eruption period lasts approximately 6-years, and the maximum subpopulation growth rate was well within plausible intrinsic limits. The Bathurst and George River subpopulations experience rates of subpopulation growth during a portion of the eruption period (9-years respectively) that exceed biologically possible intrinsic rates of growth (i.e., included immigration.
