Figure 1. The Qamanirjuaq subpopulation numbers (Nt) tracked carrying capacity (Kt) throughout its subpopulation cycle. Maximum and minimum rates of population growth (λmax = 1.19; λmin = 0.83) closely align with the maximum reported rates of barren-ground caribou population growth (λ=1.17) and population decline (λ=0.83) (Gunn, 2003). The eruption period (i.e., λ > 1.0 and increasing over consecutive years) lasted for approximately 6-years. Ntclosely tracked Kt throughout the cycle with the maximum lag time over one complete cycle (1971-2030) being 4.33-years.
