Fig. 2. Effect of photoperiod transfer on serum leptin concentration in Brandt's voles in original data (A), and after removing the effects of body mass (BM, B) and body fat mass (BF, C). Photoperiod transfer affected the serum leptin level but no differences were detected after removing the effects of body mass and body fat mass. Different letters above the bars represent a significant difference. Data are shown as means ± s.e.m. (N=8 except for SS where N=5).
