For each trait, the best distribution fit models based on log-likelihood values are highlighted in bold. Where traits were best described by a normal distribution, descriptive statistics include mean, standard deviation (s.d.) and coefficient of variation (CV). For traits best described by a log-normal distribution, descriptive statistic include median and median absolute deviation (mad); CVs were quartile based (calculated as mad/median).
