Figure 6: To visualize a third axis on Whittaker’s theory of ecosystem
organization we generated a predictive three-dimensional surface model
based on temperature, precipitation, and maximum canopy height using
data from forested NEON sites across North America (A). The data from
the three-dimensional surface was used to predict B) species richness,
C) functional redundancy, and D) functional richness for each of
Whittaker’s overlapping forest biomes along precipitation and
temperature gradients. For the model predictions we held all other
covariates at their mean, allowing only temperature, precipitation, and
maximum canopy height to vary.
