4. Dialogue

Our salient discovery was that the low metabolic rate that is characteristic of winter dormancy in cunner does not arise from metabolic rate depression, but rather from the striking reduction in activity between active and dormant states combined with the passive physico-chemical effects of cold on SMR. When variation in spontaneous movements between active and dormant states is controlled for by making comparisons of metabolic rate during night when activity was minimal (figures 1b,c and 2b), or when activity was known to be zero in both states (figure 2b,c), the acute thermal sensitivity (Q_ten) of metabolic rate of 2.8–3.2 showed typical passive thermal effects on metabolism (Q₁₀ ? 2–3 ).
