FIGURE 5. Percent weight loss during two wintering periods (A and C; Winter: Oct - early 

 Jan; B and D; Spring: mid Jan - late Mar) in Osmia lignaria populations from Nova Scotia 

 (NS) and Utah (UT) wintered in environmental chambers (In) and outside in a screened 

 building (Out). Data markers sharing letters are not significantly different (Tukey's HSD 

 test; p = 0.05); sample size in ( ) below each data marker.
