Table 3

Summary table of the GAM results, showing the influence of the chemical and physical parameters on diatom metrics. The relationships were coded as follows: “+” positive relationship; “−” negative relationship; “mid” metric favoured by medium-range values of the parameter. The metrics were ordered according to the absolute values of their loading on the PCA axes. Chemical and physical parameters are presented in descending order of their contribution to the GAM. PARAMETERS: total phosphorus (TP), conductivity (Cond), nitrate (NO3), pH, temperature (T), dissolved oxygen (DO), dissolved organic carbon (DOC), five-day biological oxygen demand (BOD5).
