An illustration of the node position randomisation procedure used to generate null distributions of the D statistic. a The original environmental raster (representing, in this case, elevation) upon which is superimposed the movement events extracted from one spatiotemporally-referenced phylogeny. b The result of one randomisation of node positions. This randomisation procedure is performed within a minimum convex hull (shown in blue), which is defined by the node locations of all selected phylogenies
