| 中文摘要: |
| 在人工饲养下,对非繁殖的扬子鳄(Alligator sinensis)体温及其所处的环境温度进行了测定,并对其体温与环境温度的关系进行了分析。经过一年的测量,得出体长为(116.83±32.26)cm(n=183)的扬子鳄年均体温为(18.81±8.08)℃(n=183),雄性体温为(20.81±9.69)℃(n=42),雌性体温为(17.81±8.56)℃(n=69);在活动期(4~11月),扬子鳄的体温为(25.54±5.24)℃(n=89),水温为(25.42±5.20)(n=89),两者间无显著性差异(P>0.05);在冬眠期(12月至翌年3月),扬子鳄的体温为(10.78±1.90)℃(n=94),冬眠期的地表温为(10.64±1.74)℃(n=94),两者间无显著性差异(P>0.05)。结果表明,扬子鳄的体温受其周围环境温度的显著影响,而不受其体长及性别的影响。即扬子鳄的体温由其长期接触的环境介质的温度决定,其中水环境是控制活动期鳄体温波动的最重要介质。初步推测扬子鳄的偏爱体温范围是28~33℃。 |

| Body temperature of non-breeding Chinese Alligators(Alligator sinensis)in captivity and the environmental temperature(water temperature and atmosphere)were measured for a whole year.The yearly body temperature of alligators with body length 116.83±32.26 cm(n=183)was 18.81±8.08℃,male was 20.81±9.69℃(n=42)and female was 17.81±8.56℃(n=69),respectiveley.The body temperature of alligator in the active period from April to November was 25.54±5.24℃(n=89),while the water temperature was 25.42±5.20℃(n=89).No significant difference was found between body temperature and water temperature(P>0.05).In hibernating period(December to March of next year),the body temperature of Alligators was 10.78±1.90℃(n=94)and the ground surface temperature at the hibernation point was 10.64±1.74℃(n=94).No significant difference was recorded between their body temperature and ground surface temperature(P>0.05).The results indicated that the body temperature of Chinese Alligators was significantly influenced by the environmental temperature,but not by its body length and gender;water environment was the most important control factor for the fluctuation of the body temperature.The prime body temperature ranged of Chinese alligators was 28-33℃。 |
