阿迪朗达克山脉 13 个高山山峰上的北极高山植物物种数量与高山生态系统的面积以及基于山峰之间距离的移民指数有关。各个群落中物种数量差异的 71% 是通过物种数量对生态系统面积自然对数的回归来解释的，其余差异的 59% 是通过移民模型来解释的，该模型假设植物繁殖体由鸟类或其他动物在山脉之间携带。结果表明，高山群落的移民是一个持续的过程，高山植物不仅仅是残存的种群。
The number of arctic-alpine plant species on 13 alpine summits in the Adirondack Mountains is related to the area of the alpine ecosystems and to immigration indices based on the distances between summits. Seventy-one percent of the variance in the number of species in individual communities is explained by a regression of species number on the natural logarithm of ecosystem area, and 59% of the remaining variance is explained by an immigration model which assumes that plant propagules are carried between mountains by birds or other animals. The results suggest that immigration is an ongoing process in the alpine communities and that the alpine plants are not merely relict populations.
