Description
Summary:Temperature is one of the important factors affecting the growth, development, and metamorphosis of amphibians. Endochondral ossification during metamorphosis plays a crucial role in amphibian survival and adaptation on land. In this study, we explored the effects of different temperature treatments on the growth, development, and endochondral ossification of Rana chensinensis tadpoles during metamorphosis. The results showed that high temperature exposure may affect the skeletal development of tadpoles during metamorphosis, such as reduction of bone length and ossification of limbs, thyroid gland damage and change of ossification-related genes expression levels，and ultimately affect the movement and survival of tadpoles in the terrestrial environment. These results provide an experimental reference for further research on the effects of temperature on amphibian growth and development and provide an important theoretical basis for the decline of the amphibian population caused by temperature. [Display omitted] •Temperature treatments caused differences in the size of tadpoles.•Warm temperature resulted in histologically evident damage to the thyroid gland.•Warm temperature inhibited the bone development of tadpoles.•Temperature treatments affected the expression of endochondral ossification genes.
