Functional trait values for 8 different traits for an assemblage of 10 species and resulting functional diversity values based on minimum functional distance, 1D(T), and total functional distance, 1D(T*).

The structure of each trait was designed to demonstrate how differences in such structure affect estimates of functional diversity. V is the total unique functional volume of Scheiner [6] used to calculate 1D(T). FAD is the functional attribute diversity measure [26], which equals total functional distance (T) and is used to calculate 1D(T*). Note that functional values are z-transformed prior to diversity calculations.
