Smooth term analysis indicated that temporal trends were highly significant in the polluted site (Ambient, polluted: edf = 5.777, p < 0.001; Warmed, polluted: edf = 5.818, p < 0.001), but were non‐significant in the non‐polluted site (SI Table S16 ). 3.2.4 Green Microalgae Concentration For green microalgae, only the June data provided sufficient variation to fit a GLM; on all subsequent sampling dates, concentrations were essentially zero.
