| 摘 要： | 对云南省19县市小兽体表蚤类生态位进行研究,并初步探讨两者间协同进化关系。采用Levins模型和Cowell-Futuymas模型分别测定47种小兽体表部分主要蚤种的生态位宽度和生态位重叠指数。生态位宽度最宽的是特新蚤（0.0987）,其次是近端远棒蚤二刺亚种（0.0749）、低地狭臀蚤（0.0734）,最窄的为伍氏病蚤（0.0216）。方叶栉眼蚤与近端远棒蚤二刺亚种生态位重叠指数最高（0.5）,与伍氏病蚤的重叠指数最低（0.0021）。印鼠客蚤与缓慢细蚤生态位重叠指数最高（0.8660）,与无值大锥蚤最低（0.0048）。蚤类生态位宽度值低,表明其与宿主动物之间的协同进化程度相对较高;生态位宽度值高,表明其与宿主动物之间的协同进化程度较低。两种蚤的生态位重叠值高,表明其在宿主选择上趋于相同或相近;反之,则差异较大。生态位宽度可以作为蚤类与其宿主动物间协同进化的一个判定指标。

| Abstract: | To investigate the ecological niche of fleas on small mammals of 19 counties in Yunnan province,the niche breadth of the dominant flea species on 47 species of small mammals was measured according to Levin's method while the niche overlap index between every two flea species studied was calculated in the light of Cowell-Futuyma's procedure.Of the 12 flea species studied,the niche breadth of Neopsylla specialis specialis was the highest and N.wualis wualis was the lowest.The niche overlap index between every... |
