中文摘要：

为比较外来种红耳龟Trachemys scripta elegans与本地种中华条颈龟Mauremys sinensis耐饥饿能力强弱,分别于2009年8月～2010年4月和2010年7～8月对外来种红耳龟和本地种中华条颈龟进行耐饥饿能力的长期（8个月）和短期（2个月）实验的比较研究。长期实验控制食物因子,短期实验控制饥饿时间。长期实验结果表明,中华条颈龟食物缺乏组体重特定增长率极显著低于食物充分组（P〈0.01）,而红耳龟体重特定增长率在两试验组之间无显著差异（P〉0.05）;在食物转化率方面,红耳龟食物缺乏组高于食物充分组,而中华条颈龟却相反。短期实验结果表明,中华条颈龟饥饿组体重特定增长率显著低于对照组（正常饲喂组）（P〈0.05）,而红耳龟饥饿组体重特定增长率与食物对照组无显著差异（P〉0.05）;中华条颈龟饥饿组肝重极显著小于对照组（P〈0.01）,红耳龟肝重两组之间差异不显著（P〉0.05）。综上表明红耳龟耐饥饿能力强于中华条颈龟。

英文摘要：

To compare the starvation endurance ability of the exotic Trachemys scripta elegans and the native Mauremys sinensis, long periods and short periods experiments on the ability of starvation endurance between the exotic T. s. elegans and the native M. sinensis were conducted from August 2009 to April 2010 and June to August 2010. In the long periods experiment the ration of food was restricted and in the short periods the duration of starvation was controlled. In the long periods experiment the results showed that the specific growth rate of M. sinensis in the starvation group was significantly lower than that of control group （P0.01）, while the specific growth rate of T. s. elegans between these two groups were not significant （P0.05）. Food conversion efficiency of T. s. elegans in starvation group was higher than that of the control, while the case reversed in M. sinensis. In the short periods experiment the results indicated that the specific growth rate of M. sinensis in starvation group was remarkablely lower than that of the control （P0.05）, while no distinct difference existed between these two groups of T. s. elegans （P0.05）. The liver weight of M. sinensis in starvation group was significantly lower than that of the control （P0.01）, while in T. s. elegans no significant difference existed between these two groups （P0.05）. Therefore, we concluded that the starvation endurance ability of exotic T. s. elegans were stronger than that of native M. sinensis.
