Second order polynomial regression analysis.

Rarefied, Chao 2 and interpolated richness were analyzed with five environmental factors for three beetle taxa. Bold faced entries indicate significant r2 (Padj) <0.05.

针对三个甲虫类群，以五个环境因子为自变量，对稀释物种丰富度、Chao2指数（Chao 2）及插值物种丰富度展开分析。其中加粗条目代表校正后P值（Padj）小于0.05的决定系数（r²）具有统计学显著性。
