变色沙蜥(Phrynocephalus versicolor)的日活动频律研究

研究地点选在新疆准葛尔盆地南缘沙漠地区,以路线统计法估计变色沙蜥的种群密度约是0.6个/100 m2,在春季白天的日平均活动频率0.501,说明平均有50.1%的个体外出活动,活动曲线为单峰曲线,每日只有一个活动高峰期,在每日的14—16点左右;在夏季白天的日平均活动频率0.199,活动曲线为双峰曲线,每日白天有两个活动高峰期,在每日的10点和20点左右,春季的活动频率明显高于夏季。

Studies on Daily Activity Frequency of Phrynocephalus versicolor

Study spot locates the southern edge of the desert area in Xinjing Zhunge'er Basin.Route statistic method is applied to our study.Population density of Phrynocephalus versicolor is about 0.6 head/100 m~2.Daily average activity frequency is 0.501 in the spring.It shows average activity unit is 50.1%.The activity curve chart is single apex chart.Daily activity fastigium is about 14:00—16:00 in the spring.Daily average activity frequency is 0.199 in the summer.The activity curve chart is two apex chart.Daily activity fastigium is about 10:00 and 20:00.Activity frequency in the spring is clearly higher than that in the summer.
