Fig. 6.

Effects of elevated temperature and CO₂ treatments on swimming speed of tadpoles at Gosner stages 36–39 (a) and 42–46 (b). Control – Ambient CO₂ (water pH = 7) and water temperature at 29 ± 1 °C; ETem32 – Water temperature elevated to 32 °C; ETem34 – Water temperature elevated to 34 °C. ECO2 – CO₂ bubbled to water to maintain pH at 5.5–5.6. Each bar is the least squares mean of three replicate measurements. Least squares means with the same letter are not significantly different at p = 0.05
