Average community cell volume plotted against the variables used in linear and multiple regression analyses for the temperature gradient (a) Water temperature at the five unheated sites.

<p>(B) Water temperature at the six heated sites. (C) The temperature anomaly during the cold season (when the reference temperature at Site G was below 12°C). (D) Dissolved inorganic nitrogen (DIN). (E) Water temperature * DIN. (F) Temperature anomaly * DIN.
