NMRs tolerate short-term anoxia. (a,b) Summaries of time active in anoxia until cessation of movement (a), time elapsed in recovery until restoration of movement (b), metabolic rate (c) and Tb (d). Data are mean ± s.e.m., n = 7 per group. Asterisks (*) indicate significant differences between normoxia and anoxia, double daggers indicate significant differences between 22 and 30°C (p < 0.05).
