Appendix 1: List of diatom taxa identified in the surface-sediment samples of 26 lakes of the BadainJaranDesert. N = number of occurrence, Max% = maximum percentage in the dataset, N2 = effective number of occurrences, EC Beta = bootstrapped beta regression coefficient for species used in the WA-PLS2inference model for Electrical conductivity (back-transformed from log10 values), SalinityBeta = bootstrapped beta regression coefficient for species used in the WAPLS2model for salinity (back-transformed for log10 values), Salinity Beta -SE and Beta +SE = beta coefficient minus standard error and plus standard error, respectively. GAM ‘class’ = range of salinity in which the species population maximumas defined by GAM occurs (“n.s.” indicates that no significant relationship with salinity was identified by GAM). GAM ‘class’ is given only for taxa with occurrence >2.
