英文摘要	Ectothermic animals are tolerant of variable oxygen availability, whether low-oxygen levels constrain the fitness of ectotherms remains unclear. Nanorana parkeri, an anuran endemic to the southern Tibetan plateau, is an excellent model with which to answer this question. In this study, we raised tadpoles of N. parkeri in oxygenated water (high-oxygen group) and deoxygenated unchlorinated tap water (low-oxygen group) and monitored their growth, mortality, and telomere length. The growth rate for body length and body weight was higher in the low-oxygen group than in the high-oxygen group. However, dissolved oxygen did not affect development time, mortality, and telomere length of the tadpoles. These results suggest that although the oxygen concentration influenced some phenotype traits of plateau tadpoles, but it didn’t influence the telomere length and survival rate, potential explanations are the local adaptation and N. parkeri tadpoles’ wide oxygen tolerance, and fluctuant toxic content that resulted in little oxidative stress on tadpoles. These results indicated that low oxygen was not a stress to N. parkeri tadpoles’ fitness and survival. This study is helpful in understanding the adaptation mechanisms of Tibetan plateau amphibians.
