Extended Data Fig. 1: Diversification dynamics are distinct for different forms of structural colouration.
From: Transitions between colour mechanisms affect speciation dynamics and range distributions of birds
Panels show support for the “structurally coloured dispersers” hypothesis H1 (a), the “tropical transitions” hypothesis H2 (b) and the “structurally coloured speciators” hypothesis H3 (c) for different range overlap cut-offs ordered by decreasing stringency (see Methods for details). Point colours indicate different colouration mechanisms: iridescent structural colour (ISC; purple) and non-iridescent structural colour (NISC; gold). Significant effects indicated with filled circles. See Fig. 4a for model details and Extended Data Fig. 5 for results for alternate phylogenies and species range map grid cell resolutions. Note different y-axis scales for each panel.
