Extended Data Fig. 4: Phylogenetic reconstruction of reef fish body size.
Maximum body length reconstructed through time across the phylogenetic tree of coral reef-associated fishes. The points represent estimated shifts in the evolutionary regime of body size detected through multi-optima Ornstein–Uhlenbeck models. Light-yellow points represent shifts toward higher values of evolutionary optima (i.e. larger body sizes), while dark-blue points represent the opposite. Please note that the y-axis is on a log10 scale. The inset depicts the number of negative shifts (i.e. towards smaller body sizes) divided by the total branch length in the phylogeny per geological epoch (y-axis) through time (x-axis). This metric gives an indication of the probability of shifts controlled by the availability of locations for them to occur. The red line represents the Cretaceous-Paleogene (K/Pg) boundary. Pi: Pliocene; Pe: Pleistocene.
