Fig. 8From: The impact of elevated temperature and CO2 on growth, physiological and immune responses of Polypedates cruciger (common hourglass tree frog)Time courses of variation of ammonia concentration in tank water in different treatments. Control – Ambient CO2 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. M – Metamorphosis; D - DeathBack to article page
