TABLE 2. Statistical results for beta diversity (total, turnover, and
nestedness) in relation to continuous fire severity (dNBR) and the
topographic variables elevation, topographic relative moisture index
(TRMI), and terrain ruggedness index (TRI). (A) Final models from adonis
tests (Vegan R package) with Sorensen dissimilarity calculated pairwise
among all plots (n=138) separately for prefire and postfire timesteps.
(B) Final models from multiple regression for matched plots
(prefire-postfire dissimilarity for each of 138 plots); since timestep
is embedded into these values, analyses do not separate pre-fire and
post-fire. Table provides F values for (A) and t-values for (B), with
statistical significance (*P <0.05,
**P <0.01, ***P <0.001). Polynomial
models were tested for topographic variables and retained when
significant (P <0.05).
