山西五鹿山地区褐马鸡集群行为研究
A STUDY ON FLOCKING BEHAVIOUR OF BROWN-EARED PHEASANT IN WULUSHAN IN SHANXI PROVINCE
【摘要】 1997和 1998年冬季对山西南部五鹿山地区褐马鸡的集群行为进行了调查 .结果表明 ,在不同的生境类型中 ,褐马鸡集群倾向略有不同 .群体大小在不同的生境中没有显著差异(Kruskal Wallis检验 ,χ2 =2 .2 7,p =0 .32 0 9,n =2 8) .褐马鸡的集群大小存在着月份间的差异 .对集群大小与月温度的相关分析表明 ,两者之间存在着显著的负相关关系 (r =- 0 .8399,p <0 0 5) .通过对五鹿山地区和芦芽山自然保护区褐马鸡的群体大小的比较 ,发现存在显著差异(Mann WhitneyU检验 ,Z =- 3 3959,p =0 0 0 7,n =4 1) ,可能与这 2个地区捕食压力和食物特征不同有关
【Abstract】 Flocking behaviour of Brown eared Pheasant was studied in Wulushan region in the south of Shanxi Province in 1997 and 1998. The results show that flocking tendency is different in coniferous deciduous forests, deciduous forests, and shrubs. Flocking size is no significant difference (KruskalWallis test, χ 2 =227, p=03209, n=28) in different habitats, but it decreases with months processed and temperature increased (r=-0 839 9, p<0 05). There are significant difference (MannWhitney U test, Z =-3 3959, p =0 007, n =41) in the flocking size between Wulushan and Luyashan Reserve, which may be resulted from different food supplies and predation pressures.
