How global warming affects amphibians is a current hot topic because temperature is the most important and variable climatic factor that affects many biological processes and is strongly related with temporal variation. Amphibians are ectotherms, which means that they receive heat from external sources and can control their temperature through their bodies or behavior. The Dybowski's frog (Rana dybowskii) is a cold-resistant species found in Northeast Asia with an extensive geographic variation in life-history traits. In this paper, the specimens were taken from Yichun, Baishan, and Shangzhi to measure body temperature and embryonic development speed. The results showed that body temperature was positively correlated with environmental temperature, and that heat increased the rate of growth, while cold temperature slowed it. The species showed higher selected body temperature, stronger temperature regulation ability, and faster embryo development speed in the hot environment than in the cold environment. There were significant differences among the three geographic populations of R. dybowskii in the selected body temperature. The crossing point temperature at which the linear regression equation intersects with isothermal line (y=x) was the lowest in the Yichun population (18.51℃ for males and 21.74℃ for females), and was the highest in the Shangzhi population (20.00℃ for males and 23.06℃ for females). The body temperature of the Yichun population was the lowest, while that of the Shangzhi population was the highest among the three populations under the low temperature conditions (8-22℃ for males and 8-26℃ for females). In contrast, body temperature of the Yichun population was the highest, while that of the Shangzhi population was the lowest under high temperature conditions (24-30℃ for males and 28-30℃ for females). Thermoregulation ability of the Shangzhi population was the strongest, followed by the Baishan population, and the Yichun population was the weakest among the three populations. The embryonic development time of the Shangzhi, Baishan, and Yichun populations increased successively and the gaps among the three populations were becoming increasingly obvious with the development of embryos. The development completion time of different stages was not reduced in proportion with the increasing of ambient temperature. The second and third stage of embryonic development, and the 21^st phase (mouth open stage) of the fourth stage were significantly shortened. This indicates that different embryo development stages have different sensitivity to temperature, and that heating can accelerate the developmental rate during certain developmental periods of this species. Thus, tadpoles and developing frogs are more susceptible to temperature than adults. This may lead to changes in morphological structure and functions in some organs. In summary, body temperature and embryonic development are different among the three geographic populations of R. dybowskii, which is a type of adaptive evolution to the environment. The temperature rise has an effect on all populations under the background of global warming. We conclude that different geographic populations have different adaptation strategies to cope with the change of environmental temperature. This study provides a basis for the artificial breeding of amphibians and the adaptation mechanism to climate change in the future.
