  		Fig. 1. Relative mobilization of fatty acids from ruff adipocytes. Fatty acids are ordered from least to most mobilized according to Raclot's studies in rats (Raclot, 2003Go).

  		Fig. 2. Relative mobilization of fatty acids from ruff adipocytes in relation to the number of double bonds. The value for 18:3 is the mean of 18:3n3 and 18:3n6. The number of double bonds and chain length both had significant effects on relative mobilization (P<0.001). See text for statistical details.

  		Fig. 3. Relative mobilization of fatty acids from white-crowned sparrow adipocytes. Fatty acids are ordered from least to most mobilized according to Raclot's studies in rats (Raclot, 2003Go). There are no significant differences in relative mobilization of any fatty acid according to migratory state or exercise (P>0.133). MIG=migrant, WIN=winter. Values are means ± s.e.m.
