Table 1. Generalized Additive Mixed Model (GAMM) structures.
α + f | Temporal trend and absolute abundances are treatment-independent (Model Trtmt_indep) |
α + fT | Temporal trends depend on the treatment, but absolute abundances are treatment independent (Model Trtmt_trend) |
αT + f | Absolute abundances depend on the treatment, temporal trends are treatment independent (Model Trtmt_absAb) |
αT + fT | Both absolute abundances and temporal trends are affected by the treatment (Model Trtmt_absAb_trend) |
