Trophic interactions modify the temperature dependence of community biomass and ecosystem function
Table 7
Results of model comparison for effects of temperature and time on ER based on AIC weight (w) and δAICC values.
Nested versions of the full model (Methods, Eq 12). Response variables are modeled as functions of temperature Twj for each tank j on week w relative to the mean temperature TM for tank j over all weeks (T in Kelvin), and trophic structure (Zj). Models included a random effect for the experimental unit—tanks with and without predators received the same power inputs. The model was fit to 240 observations in 30 groups. See “Methods: Statistical analyses” for additional details on modeling.
