Table 3.

Metrics for metabolic rate reported in the literature. Activation Energy (Ea) values (in eV) indicate the thermal sensitivity of oxygen consumption rates. Critical oxygen levels (Pc) are listed alongside with the oxygen consumption rate at Pc, expressed as a percentage of the initial oxygen consumption rates at normoxia (see text for further explanation). Numbers refer to literature sources: 1: Adcock, 1982; 2: Becker, Ortmann, Wetzel, & Koop, 2016; 3: Bruijs, Kelleher, Van der Velde, & Bij de Vaate, 2001; 4: Dorgelo, 1973; 5: Foucreau, Cottin, Piscart, & Hervant, 2014; 6: Franke, 1977; 7: Hervant, Mathieu, & Messana, 1998; 8: Issartel, Hervant, Voituron, Renault, & Vernon, 2005; 9: Lukacsovics, 1958; 10: Maazouzi et al., 2011; 11: Micherdzinski, 1958; 12: Mösslacher & Creuzé des Châtelliers, 1996; 13: Nilsson, 1974; 14: Pieper, 1978; 15: Prus, 1976; 16: Rotvit & Jacobsen, 2013; 17: Roux & Roux, 1967; 18: Roux, 1975; 19: Roux, Roux, & Opdam, 1980; 20: Rumpus & Kennedy, 1974; 21: Suomalainen, 1958; 22: Toman & Dall, 1998; 23: Walshe‐Maetz, 1956; 24: Wautier & Troiani, 1960; 25: Woynárvich, 1961
