Extended Data Fig. 4: Comparison of material legacy variables between overwintering (O) and single season (S) fires in the Northwest Territories (NT) and Alaska (AK).
From: Overwintering fires can occur in both peatlands and upland forests with varying ecological impacts
Boxplots showing distribution of material legacy variables; plots include median, 1st and 3rd data quartiles and outliers. Model results are presented in Supplementary Table 2. Samples sizes for residual soil organic layer thickness (rSOL) were as follows: NT, n = 75 (9 overwintering and 6 single season fire sites with 5 nested plots per site] and AK, n = 66 (7 overwintering and 4 single season fires sites with 6 nested plots per site). Deadstanding and deadfallen basal area (BA) were measured at the stand level meaning n = 15 for NT and n = 11 for AK.
