Linear relationships between the effect of warming on plankton processes, environment variables and pigment concentrations. Ordinary least squares linear relationships between the effect of warming, expressed as the log response ratio, on GPP, R, µ, and l, and the effect of warming on environmental and pigment variables for the spring (blue circles) and fall (green squares) experiments. Relationships were individually assessed for each experiment. Only statistically significant relationships (p < 0.05) are represented and solid blue lines represent the linear least square fit for the spring experiment while solid green lines represent the linear least square fit for the fall experiment. (A) Gross Primary Production (GPP) vs Respiration (R), (B) growth rate (µ) vs loss rate (l), (C) µ vs NH4+, (D) µ vs NO2− + NO3−, (E) µ vs fucoxanthin, (F) R vs fucoxanthin, (G) µ vs chlorophyll-b (Chl-b), (H) µ vs zeaxanthin, (I) R vs PO43−, (J) GPP vs NO2− + NO3−, (K) GPP vs peridinin.
