Figure 2:

The standard metabolic rate (${\dot{V}}_{{\mathrm{O}}_2}$; in millilitres of O₂ per hour) of L. peronii tadpoles exposed to control and UV-B treatments measured during the initial stage of exposure (A; experienced from week 0 to 3 of the exposure period; absolute irradiance of UV-B during peak = 12.9 ± 3.18 µW cm⁻²; control, n = 28 and UV-B, n = 35) and during the final stage of exposure (B; experienced from week 3 to 6 of the exposure period; absolute irradiance of UV-B during peak = 18.41 ± 3.55 µW cm⁻²; control, n = 27 and UV-B, n = 25). There was no significant effect of larval UV-B exposure on standard metabolic rate rate at either the initial or the final stage of the exposure period. Data are presented as mean values + SEM.
