(A) Femur break force during the summer as a function of the date of sampling. Symbols represent individual bone measurements; N=11 animals. Not all bones were available from each squirrel. The date of sampling during the summer has no effect on femur break force (r²=0.09; P>0.05, ANOVA). (B) Tibia break force during the summer as a function of the date of sampling; details as in A. The date of sampling has no effect on tibia break force (r²=0.02; P>0.05, ANOVA).
