| 英文摘要 |
A male-biased sampling of Chinese green tree viper, Trimeresurus s. stejnegeri, was found at Tsao-chiao study site. Animal skewed sex ratio may induced by various reasons. Although unlikely, the skewed sex ratio at birth was still found in a few snake species. Sampling bias and/or differential mortality rate between sexes are more likely to be the causes of the observed skewed sex ratio. The aim of this study is to find out the cause of this skewed sex ratio. |
