Fig. 4 in Molecular phylogenies map to biogeography better than morphological ones
Fig. 4 The number of morphological and molecular trees most congruent with biogeography. Comparison of the number of trees in each sample (morphological or molecular) with a greater biogeographic fit than its counterpart. a Consistency index (CI), grey bars show totals for the whole sample, coloured bars indicate totals in the subset significantly different from the expected null (CI & RI p value <0.05). b Retention index (RI), grey bars show totals for the whole sample, coloured bars indicate totals in the subset significantly different from the expected null (CI & RI p value <0.05). c P values for the CI & RI random permutations (CI & RI p value), where grey bars show totals for the whole sample, coloured bars are clades with values <0.05. d biogeographic HER (bHER), counts are for the whole dataset. Bars show the number of clades in each subset, with binomial confidence intervals calculated using the approach of Clopper and Pearson103. N = 48 biologically independent pairs of morphological and molecular phylogenies.
Fig. 1 in Molecular phylogenies map to biogeography better than morphological ones
Fig. 1 Testing the biogeographic congruence of phylogenetic trees. a Defining biogeographic regions and coding taxon presences and absences. 1. Occurrence data on the distribution of extant species is used to produce a list of biogeographic regions for the clade and to summarise ranges for the taxa in the published phylogenies. 2. This distributional information is converted into a matrix of binary characters representing taxa in biogeographic regions, where 0 indicates the taxon is absent and 1 indicates the taxon is present. 3. Characters in the occurrence matrix are mapped onto the morphological and molecular phylogeny selected for each clade, allowing standard measures of character fit (CI, RI) to be calculated for each tree. b Presence and absence codings in each matrix are randomly reassigned to taxa, keeping the presence and absence codings fixed for each row. Characters form the new randomly permuted matrix are mapped onto the original trees and both CI and RI are recalculated. The entire randomisation process is performed 10,000 times. c The 10,000 CI and RI values from matrices' biogeographic region reassignments form a null distribution of expected congruence values if taxa in the clade were randomly distributed in biogeographic regions. The observed CI and RI of region characters for a given tree is compared to the null distribution for that same tree to determine whether the observed biogeographic congruence value lies outside of the 95% confidence interval.
Fig. 2 in Molecular phylogenies map to biogeography better than morphological ones
Fig. 2 Biogeographic congruence in morphological and molecular phylogenies. Binary biogeographic region characters mapped onto paired morphological and molecular phylogenies. a Placental mammals (Eutheria) from O'Leary et al. 2013100. b Caribbean boas (Chilabothrus/Epicrates), with the morphological tree taken from Kluge 1989101 and the molecular tree taken from Tolson 1987102. Regions for which the terminal taxon is coded present are represented as coloured pie slices. Consistency index (CI), retention index (RI) and biogeographic HER (bHER) values given are for the matrix of biogeographic region presences and absences, while CI & RI p value is calculated using 10,000 randomly permuted region matrices.
