`Autumn activity' corresponds to late autumn, and `arousal' to unfed,rehydrated animals in Table 1. Values are the mean ± 1 s.e.m. from six animals in U g⁻¹ wet mass; ^a indicates significant differences from autumn activity; ^b from winter dormancy; ^c from arousal; ^d from spring activity (P<0.05). IL,iliofibularis, white portion.
