Evolutionary patterns of integration among variables that describe the functional morphology of feeding in the Danioninae. A. Connections between variables indicate that phylogenetic generalized least squares (PGLS) analyses showed their evolution to have been significantly correlated (see Table 4). All correlations were positive. For the five cases in which variables were analyzed in two versions (both raw measurements and measurements adjusted by standard length; see Table 1), only the adjusted measurements were included for the sake of clarity (raw measurements are included in Supplementary Fig. S1). B. A functional and evolutionary module of danionine feeding mechanics. The evolution of these variables has been highly integrated.
