Metadata for the evenness model in McCarthy et al. 2018, Ecography (RAD_Evenness_data.csv) See the supporting information for additional variable information (including references; Appendix 2, Table A1) and model selection (Appendix 6, Table A1). Note that all values were extracted from standardised environmental layers (mean = 0, SD = 1). Mean and standard deviations of the original layers are provided in the description of each variable for back-conversion. Environmental variables are identical within each site (i). Column Description i Site identifier (matched with evenness dataset, RAD_Evenness_data.csv). N Total site abundance, stems/1000 m2 (see Methods). S Total site species richness, species/1000 m2 (see Methods). nij Species level abundances; length of S, sums to N within i. SEQ_MinTempColPer Minimum temperature of the coolest period (mean = 7.3396, SD = 2.2770). SEQ_SolDep_new Soil depth (mean = 1.0476, SD = 0.1611). SEQ_C3Meso C3 mesophyll plant growth index (mean = 0.4651, SD = 0.1225). SEQ_AWC Available water capacity (mean = 13.7534, SD = 1.0333). SEQ_SolSand Sand content (mean = 55.9139, SD = 8.6495). SEQ_FireScar Fire frequency (mean = 1.5006, SD = 2.0214).
