Figure S4. from Growth overshoot and seasonal size changes in the skulls of two weasel species

Boxplots showing the distribution and mean of braincase depth (top) and standardized braincase depth (BDs, bottom) of M. erminea (left) and M. nivalis (right) per age, sex, and origin grouping. Alternating grey vertical bars distinguish origins. Sexes (F, female; M, male) are separated by color, with increasing darkness within sex and origin indicating increasing age category (J, juvenile; S, subadult; A, adult). Outliers indicated with increased point outline thickness. There are no juvenile male M. erminea from Ontario included within our analyses. Note: scales vary between species and metrics.
