A conceptual framework integrating the degree of phylogenetic signal in plant-soil habitat associations and the phylogenetic structure of the assemblage.
Figure 1.
A comparison of the family-level relationships within the Asterid clade.
The topology on the left-hand side represents the phylogenetic relationships of families obtained from the APG III consensus phylogeny, while the topology on the right-hand side represents the DHS phylogeny generated with the ML analysis of the barcode sequence data.

The spatial distribution of the five habitat types in the 20-ha Dinghushan plot.
Colors represent different habitat types at the spatial scale of 20 m×20 m.

Figure 3.
The spatial patterns of NRI and NTI values in the forest plot.
Values of NRI and NTI for each 400 m2 quadrat in the 20-ha forest dynamics plot in Dinghushan, south China, are calculated using the molecular phylogeny and the Phylomatic phylogeny. Negative NRI and NTI values indicate phylogenetic overdispersion and positive values indicate phylogenetic clustering. The color scales across all NRI and NTI maps are made equivalent to allow for direct visual comparisons between the four maps. a. Barcode NRI; b. Phylomatic NRI; c. Barcode NTI; d. Phylomatic NTI
Table 4.
The estimated mean and standard error of the NRI and the NTI values in the DHS habitat types estimated using first order simultaneous spatial autoregression for the molecular phylogeny (columns labeled “Molecular NRI/NTI”) or for the Phylomatic phylogeny (columns labeled “Phylomatic NRI/NTI”).
Figure 4.
The total distributions of NRI or NTI values in different habitats generated from the molecular and Phylomatic phylogenies.
The solid black line across the color box represents the median value. A hollow circle indicates an outlier value of NRI or NTI. HS, High-slope; RT, Ridge-top; HG, High-gully; LS, Low-slope; V, Valley.
