Summary results of the information theoretic approach for relationships between predictor variables and <i>observed species richness</i> of flightless ground beetles, showing (a) summed Akaike weights from observed data, (b) mean summed Akaike weights from randomised data, (c) standard deviation (SD) of summed Akaike weights, standardised effect size ((a-b)/c), and <i>P</i> values calculated from 999 null models generated by permutation.

Hist.veg = historical vegetation stability; Treefall = disturbance from treefalls; Ave.T = annual mean temperature; Seas.P = precipitation seasonality; Seas.T = temperature seasonality; Litter = fine-litter standing crop; AWC = available water capacity; TWI = topographic wetness index; Ann.P = annual precipitation; Latitude = plot latitude; Aspect = plot aspect; Habitat = habitat heterogeneity of forest floor. Predictor variables displayed in bold were significant.Hist.veg = 历史植被稳定性（historical vegetation stability）；Treefall = 林木倒伏干扰（disturbance from treefalls）；Ave.T = 年平均气温（annual mean temperature）；Seas.P = 降水季节性（precipitation seasonality）；Seas.T = 气温季节性（temperature seasonality）；Litter = 细枯落物现存量（fine-litter standing crop）；AWC = 有效持水量（available water capacity）；TWI = 地形湿度指数（topographic wetness index）；Ann.P = 年降水量（annual precipitation）；Latitude = 样地纬度（plot latitude）；Aspect = 样地坡向（plot aspect）；Habitat = 林地表生境异质性（habitat heterogeneity of forest floor）。以粗体标注的预测变量具有统计学显著性。
