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.
