Abstract:Predation risk is one of the most important selective forces for the phenotype and life history of amphibian larvae during evolution. Water level fluctuation often increased the predation risks on the larvae of Tylototriton shanjing, which is a typical caudate amphibian species in montane environment of Yunnan province, China. In this study, effects of predation risks on early ontogeny of T. shanjing had been explored by observing the variations of body length and body mass, as well as the differences of time at metamorphosis under different predation risk situations. Four treatments were designed to investigate the predation risk of T. shanjing:no predation treatment, conspecific individuals' treatment, injured individuals treatment, and invasion predators treatment. Finally, we observed that newt larvae showed different growth and development under different predation risk conditions. In the early stage of the development, the growth rates of the newt larvae in the four treatments were identical. However, significantly increased growth rate of newt larvae was observed at the middle and late stages in the predation risk treatment group. Body length and body mass of the newt larvae at metamorphosis stage after the predation risk treatment was much longer and heavier than those of the no predators treatment. Moreover, the time duration of metamorphosis stage of predation risk treated newt larvae were shorter than those of the no predation risk treatment. These results suggested that newt larvae adapt to high predation risk environment by speeding up the growth rate at late stage of embryonic development and shortening the time duration of metamorphosis.
