Models of species richness in N = 25 European countries.

Abbreviations: PDR = productivity-diversity relationships, AE = ambient energy, IGM = interim general model, SEH = spatial environmental heterogeneity, Herbi = herbivores, Carni = carnivores. “NA” indicates cells that were excluded from the respective models. Empty cells were considered, but the respective explanatory variable did not remain in the model according to the second order Akaike Information Criterion (AICc). I-lm denotes Moran’s I correlation coefficient for the residuals of a linear regression model not corrected for spatial autocorrelation. I-sar denotes the respective Moran’s I for spatial autoregressive error models. AICc and r2 values are from the spatial regression models, whereby r2 is Nagelkerke’s pseudo r2 based on maximum likelihood. Values in the columns of environmental variables are model coefficients, with significance levels denoted by asterisks:*pppaCook’s distance was >0.5 for Portugal. When excluded, T no longer remained in the model.bCook’s distance was >0.5 for Portugal. When excluded, the slope for T became slightly steeper (434.37*).cCook’s distance was >0.5 for Portugal. When excluded, the slope for T became slightly flatter (153.17*).dCook’s distance was >0.5 for Portugal. When excluded, none of the IGM variables remained in the model.缩写说明：PDR为生产力-多样性关系（productivity-diversity relationships），AE为环境能量（ambient energy），IGM为过渡通用模型（interim general model），SEH为空间环境异质性（spatial environmental heterogeneity），Herbi为草食动物（herbivores），Carni为肉食动物（carnivores）。"NA"表示从对应模型中剔除的单元格。空单元格虽被纳入考量，但根据二阶赤池信息准则（Akaike Information Criterion, AICc），对应的解释变量未被保留于模型中。I-lm指代未校正空间自相关的线性回归模型残差的莫兰I（Moran’s I）相关系数；I-sar指代空间自回归误差模型对应的莫兰I系数。二阶赤池信息准则（AICc）与决定系数（r²）均来自空间回归模型，其中r²为基于极大似然估计的内格尔克伪决定系数（Nagelkerke’s pseudo r²）。环境变量列中的数值为模型系数，显著性水平由星号标注：*ppp。 a. 葡萄牙的库克距离（Cook’s distance）大于0.5。将其排除后，变量T不再保留在模型中。 b. 葡萄牙的库克距离大于0.5。将其排除后，变量T的斜率略微变陡（434.37*）。 c. 葡萄牙的库克距离大于0.5。将其排除后，变量T的斜率略微变缓（153.17*）。 d. 葡萄牙的库克距离大于0.5。将其排除后，无任何过渡通用模型（IGM）变量保留在模型中。
