Table 2.
Quantitative trait variation by temperature treatment (treatment) and site. Values per site (mean values are shown with their associated standard deviations) are shown for the diameter of Rana temporaria eggs at collection (egg size); the weight at metamorphosis minus the weight at hatching (metamorphic weight); the number of days between hatching and metamorphosis (larval period); the gain in snout-vent length (SVL) between hatching and metamorphosis (SVL gain); the increase in weight per day during the larval period (growth rate); and the percentage of tadpoles that survived from hatching to metamorphosis (survival)
| Site | Treatment (°C) | Egg size (mm) | Metamorphic weight (g) | Larval period (days) | SVL gain (mm) | Growth rate (mg/day) | Survival (%) |
