Table 1.
Environmental characteristics and generalized results of ‘nodesig’ analysis (i.e., over and underrepresented lineages) for 15 protected forests in Puerto Rico.
Figure 1.
A map of Puerto Rico including the 15 state forests used in this study [90].
Forest life zones are coded as: subtropical dry (df-S), subtropical moist (mf-S), subtropical wet (wf-S), lower montane wet (wf-LM), subtropical rainforest (rf-S), lower montane rainforest (rf-LM). Refer to Table 1 for forest codes.
Figure 2.
A maximum likelihood phylogeny constrained at the ordinal level representing 526 native and naturalized tree species of Puerto Rico (the single tree fern in the phylogeny is excluded to aid visualization).
Ordinal placement according to APG III [60] is color coded.
Figure 3.
The net relatedness index (NRI) (A, B) and nearest taxon index (NTI; C, D) based on species occurrence records from Little & Wadworth [63] and Little et al. [64] versus reserve area [90] for 15 state forests in Puerto Rico.
Leftmost panels are based on a null model using the full island species pool; right panels (B, D) are based on species pools restricted to primary soil types. Forests are sorted from left to right in order of their mean annual precipitation. Positive values indicate phylogenetic clustering and negative values indicate phylogenetic evenness. Filled symbols indicate values that are significantly different from a null model. Refer to Table 1 for forest codes.
