| 摘 要： | 研究了青海沙蜥(Phrynocephalus vlangalii)成体的选择体温、热耐受性及食物同化和运动表现的热依赖性。结果显示:选择体温、临界低温和临界高温无显著的两性差异,其平均值分别为33.3、0.9℃和46.9℃。在27-35℃实验温度范围内,体温显著影响日摄食量,表观消化系数(ADC)和同化效率(AE)无显著影响。停顿次数随着体温的升高而降低,至39℃时停顿次数最少,但与37℃和41℃处理下的停顿次数无显著差异。疾跑速在17-39℃范围内随体温升高而加快,在39℃体温下最快。体温大于39℃后速度减慢。在17-27℃体温范围内,随体温的升高持续运动距离无显著差异。持续运动距离在29-41℃体温下大于较低体温(17-27℃)下的测定值。

| Abstract: | Temperature is the single most important environmental factor affecting many biological processes in organisms.Ectotherms are viable under a wide range of body temperatures,but their physiological processes and behavioral performances are usually maximized at moderate to relatively high body temperatures.We collected Qinghai toad-headed lizards(Phrynocephalus vlangalii;Agamidae) in August 2005 from a population in Qinghai(northwestern China) and used adults to study selected body temperature(Tsel),thermal t... |
