Figure 7: Comparison of lag times (years to reach Ktfrom Nt) and mean population growth rates from the eruption years only for the Qamanirjuaq, Bathurst, and George River subpopulations. Three clusters were identified: 1) short lags and high lambda values, 2) intermediate lag time and intermediate lambda values, and 3) long lag time and low lambda values. Cluster 1 was associated with only three George River eruption year records, all of which had over 70% immigration. Most (7/9) eruption year records for the Bathurst subpopulation were associated with intermediate cluster 2. Intermediate cluster 2 also contained two Qamanirjuaq eruption year records, and four George River eruption year records. Most (4/6) eruption year records for the Qamanirjuaq subpopulation were associated with cluster 3.
