Fig. 2. Regressions of logM_sum (A) and logT_CL (B) against logM_b in summer (solid line) and winter (broken line). At both seasons, logM_sum was significantly and positively associated with logM_b and logT_CL was significantly and negatively related to logM_b. Winter equations were significantly elevated for logM_sum and significantly lower for logT_CL than summer equations, suggesting that winter increases in M_sum are correlated with decreases in T_CL.
