Relationships of substrate parameters to life history mode. Regression plots (left) of independent contrasts of substrate parameters (A, proportion of sand and granule; B, proportion of small/medium gravel; C, degree of sorting; D, proportion of chert) versus independent contrasts of life history mode. Histograms (right) represent the distribution of r2 values based on 1000 MCMC randomizations of the original data. Arrows indicate location of observed r2 relative to the randomized distribution.
