Relative contributions of rare and common species to the multiple-scale patterns of species diversity in Quercus wutaishanica communities on the Loess Plateau
Understanding the overall patterns of spatial variation in species diversity and how these patterns are affected by species distribution is a key issue in species diversity studies,which facilitates biodiversity conservation and management.Alpha( α),beta( β),and gamma( γ) species richness and the Shannon diversity index of Quercus wutaishanicacommunities were analyzed by additive partitioning across four different nested spatial scales,i. e.,α1 scale( within subplots),β1 scale( among subplots),β2 scale( amo...
