What will happen to species diversity in a forest when exploitation of the canopy foliage terminates? The foliage of the main canopy tree of a mountain evergreen oak forest was harvested at different intensities prior to a forest survey in 1993 and resampled in 2013 after the harvest of canopy foliage ceased (1995). We predict a decrease in herbaceous species richness with increasing canopy cover, and an opposite trend for vines and woody species. We hypothesise that plant species’ alpha and beta diversity will change most in the plots where foliage was most intensively harvested while showing less change in the plots that underwent almost no harvesting.

停止森林干扰后植物物种丰富度的变化

当冠层叶子的开发终止时，森林中的物种多样性会发生什么？在1993年进行森林调查之前，以常绿橡木林的主要冠层树的叶子进行了采伐，然后在停止冠层采伐（1995年）后于2013年重新取样。我们预测，随着树冠覆盖率的增加，草本物种的丰富度将下降，而藤本植物和木本植物则呈现相反的趋势。我们假设植物物种的α和β多样性在收获最密集的地块中变化最大，而在几乎没有收获的地块中变化较小。
