“…During the early larval period, as well as during embryogenesis, oxygen con sumption grows faster than mass, and the power coef ficient k exceeds one (Ozernyuk, Lelyanova, 1985;Ozernyuk, 2000;Vladimirova et al, 2003Vladimirova et al, , 2010. After the larva switches to external nutrition, the ratio between these coefficients changes; the value of the power coefficient k lies in the range between 0.78 and 1 in most studied amphibian species and does not change until metamorphosis (Funkhouser, Mills, 1969;Feder, 1982;Vladimirova et al, 2003). During the metamorphosis process, the parameters of the dependence between oxygen consumption and body mass change in some amphibian species (Feder, 1982;Beck, Congdon, 2003) and remain the same as earlier in others (Funkhouser, Mills, 1969).…”
