Fig. 2

Variation of morphometric characters of tadpoles such as (a) Total body length, (b) Snout-Vent length, (c) Tail length and (d) Body width with time after hatching in different treatments. 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 data point is a mean of three replicates. M – Metamorphosis; D – Death. Lines indicate second-order polynomial curves. Red circles indicate the Control group. Grey triangles indicate the ETem32 group. Green squares indicate the ETem34 group. Blue diamonds indicate the ECO2 group
