Other Abstract

作者提供了2001~2002两年间青海沙蜥(Phrynocephalusvlangalii)的标志重捕资料,并讨论了在种内水平上可能影响青海沙蜥巢域面积的因素,如性别、年龄、体重、种群密度以及扩散行为等.若尔盖辖曼乡青海沙蜥的种群密度偏高,为(238.92±16.88)只/1000m2,而巢域偏小,幼体、成体雄性及成体雌性的平均巢域分别是(26.11±10.67)m2、(63.71±31.43)m2和(8.31±5.44)m2.性别仍然是影响青海沙蜥巢域的最明显的因素,雄性与雌性巢域的比例达到了7.6∶1.另外体重也是影响巢域的因素之一.雌雄性均与多只异性发生巢域重叠,最高的雌性可与6只雄性有巢域的重叠.雄 雄的平均巢穴重叠达到了24.17%,而雌性间没有重叠. 


The mark-recapture data of Phrynocephalus vlangalii were presented from 2001 to 2002. Home ranges of each individual were estimated and the influence factors were discussed such as sex, age, body weight, population density and dispersal action. The population density of P. vlangalii was quite high with a number of 238.92 ± 16.88 individuals/1000m~2, while the sizes of home ranges were rather low. The average home range size of juveniles was 26.11 ± 10.67m~2, adult males, 63.71 ±31.43m2, and that of adult females was 8.31 ± 5.44m~2. Sex was the most distinct factor which influences home range, and the ratio of the home range size of males to that of females achieves 7. 6 to 1.0. Also, home range was affected by body weight. The home ranges of Both adult males and adult females overlap with those of several heterosexul individuals, and one female's home range could overlaps with 6 males. Overlaps between males achieve 24.17% , but there were no overlaps between females.
