— = no covariate was used; AIC = Akaike’s information criterion; ∆AIC = the difference between the AIC of the best model evaluated for that test and the model being reported; GDVI2 = generalized difference vegetation index; GNDVI = green normalized difference vegetation index; GRE = green; NDVI = normalized difference vegetation index; NIR = near infrared; REG = red edge; VI = vegetation index.
