表2 R语言“vegan”包的甲螨多度及环境和空间因子数据集

Table 2 Oribatid mites abundance dataset with environmental and spatial variables in R package “vegan”

数据框 Data frame 介绍 Description mite 物种多度矩阵, 包含70个采样点的共计35种甲螨形态种的个体计数 Species abundance matrix that contains the abundance of 35 oribatid mites morphospecies at 70 sampling sites mite.env 环境因子矩阵, 包含70个采样点的共计5种环境变量: 基质密度、基质含水量、基质类型、灌丛密度和微地形特征 Environmental matrix that contains 5 environmental variables at 70 sampling sites, including substrate density, water content of the substrate, substrate type, shrub density, and microtopography mite.pcnm 空间因子矩阵, 基于70个采样点的地理坐标, 通过邻体矩阵主坐标分析(PCNM)构建的特征向量, 反映了70个采样点的潜在空间结构 Spatial matrix, which is based on the geographic coordinates of 70 sampling sites and constructed by principal coordinates of neighbour matrices (PCNM) (Borcard & Legendre, 2002), represents the potential spatial structure of 70 sampling points
