Table 1. Summary statistics for the Qamanirjuaq, Bathurst, and George
River barren-ground caribou cycles. The sine cycle maximum and minimum
annual subpopulation growth rates (λt) were updated from
Bongelli et al. 2020. Sine cycle estimates of λtgreater than the biologically plausible were limited to 1.2
(λplausible) with the remainder of population growth for
those years attributed to immigration. Subpopulation growth that was
partially immigration (intrinsic + immigration) occurred only during the
eruption phase.
