对华盛顿州4个亚高山草甸的植物群落进行了研究。生态位宽度和种类的结果。重叠作为竞争强度的函数。优势种包括爱达荷羊茅、羊毛毡苔、福禄考、绵毛苔、苔草、羽扇豆、中间丹、细毛无心菜和褐头苔草。随着竞争强度的增加，优势种的生态位宽度。空间保持物种之间变化不大，重叠。增加平均生态位宽度，竞争劣势种生态位宽度，总重叠和弱竞争者之间的重叠下降。
The plant communities of 4 subalpine meadows in Washington state were studied. Results on niche width and spp. overlap as a function of competitive intensity are presented. Dominant spp. included Festuca idahoensis, Eriophyllum lantanum, Phlox diffusa, Antennaria lanata, Carex spectabilis, Lupinus latifolius, Danthonia intermedia, Arenaria capillaris and Carex phaeocephala. With increase in competitive intensity, niche width of dominant spp. changed little and overlap between space-holding spp. increased. Mean niche width, niche width of competitively inferior spp., total overlap and overlap among weak competitors declined.
