Table 4 Pyrodiversity metric models describing plant Simpson’s diversity in order of increasing model Akaike Information Criterion (AIC) values (Table 2; Additional file 2: Equation 2.2) in the Illilouette Creek basin in Yosemite National Park and Sugarloaf Valley in Kings Canyon National Park, California, USA. The analysis using Equation 3 (Additional file 2: Equation 2.3) included functional divergence at 100 m. Public data were collected beginning in early 1900s. Field data were collected from 2002 to 2013 to observe naturally occurring patterns of forest and understory structure and composition in relationship to fire regime
