Abstract

<ol> <li> </li> </ol> Activity oxygen consumption rates (V O2 max) were determined for a variety of amphibians using both electrical and manual stimulation to elicit and maintain activity. The suitability of manometric measurement of V O2 max was also evaluated. <li> </li> V O2 max (units, ml/g·h) for three minute activity periods induced by manual stimulation were: Hylaregilla , 1.06±0.10; Hyla cadaverina , 1.25±0.14; Batrachoseps attenuatus , 0.82±0.08; Ensatina eschscholtzi , 0.37±0.6; and Aneides lugubris , 0.70±0.25. V O2 max was 4 to 6 times greater than previously reported values. In all species, V O2 during activity was greater than V O2 during recovery (Tables 1, 2). <li> </li> V O2 in burst activity (3 min) is about 20% greater than V O2 in sustained activity (30 min) in Rana pipiens (Fig. 1). V O2 max was 3 times greater than previously reported values. <li> </li> Electrical stimulation can lead to physiological impairment of aerobic metabolism as evidenced by a decline in V O2 with increasing stimulus duration and frequency (Table 1). Electrical stimulation can also lead to errors in V O2 as a result of electrolytic gas generation (Fig. 2). <li> </li> Manometric measurement of V O2 can seriously underestimate actual oxygen consumption rates because of temperature transients, resulting from both biological and electrical heat production (Fig. 2). Temperature transients also lead to an apparent delayed development of V O2 after the activity about.
