Diversity of spider communities.

Diversity of spider communities collected by insecticidal knock down from deciduous and coniferous trees in Poland. Rarefaction values (RAF) computed on standardized individual numbers (ind) allow direct comparison suggesting large differences in species diversity among tree species (Qr = Q. robur, Cb = C. betulus, Ag = A. glutinosa, Bp = B. pendula, Pt = P. tremula, Pa = P. abies, Ps = P. sylvestris).

本数据集为波兰境内采用杀虫剂击倒法采集自落叶树与针叶树的蜘蛛群落多样性数据。基于标准化个体数（standardized individual numbers，ind）计算得到的稀疏化值（Rarefaction values，RAF）可开展直接比对分析，结果显示不同树种间的物种多样性存在显著差异：Qr = Q. robur、Cb = C. betulus、Ag = A. glutinosa、Bp = B. pendula、Pt = P. tremula、Pa = P. abies、Ps = P. sylvestris。
