F I G U R E 3 in Cutting the Gordian Knot: Phylogenetic and ecological diversification of the Mesalina brevirostris species complex (Squamata, Lacertidae)

F I G U R E 3 Results of 100 replicates of niche identity (above diagonal) and background tests (below diagonal). Observed niche overlap (Schoener's D) is given in the upper right corner of each graph and is also indicated by red bars. The identity tests show that the niches are significantly different from models based on pooled and randomly resampled records for all species pairs except M. bernoullii—M. microlepis. Scales of the x axis of all identity tests are 0–1. Background tests show two comparisons, one of the occurrences of the species in row against the background for the species in column (black bars and p values), the other of occurrences of the species in column compared with the background for the species in row (grey bars and p values). Note that the scale of the x axes differs in the background graphs. Asterisks by p values denote significant results. Names of taxa correspond to changes proposed in this study
