The benefits of being dominant: health correlates of male social rank and age in a marmot.

After controlling for significant variation explained by age (Estimate = 0.056, SE = 0.017, P = 0.002; Table 2 and Figure 2C ) and body mass (Estimate = −0.047, SE = 0.020, P = 0.020; Table 2 and Figure 2D ), the N/L ratio had a nonsignificant trend to decrease with relative rank (Estimate = −0.026, SE = 0.015, P = 0.076; Table 2 and Figure 2A ).
