Trophic interactions modify the temperature dependence of community biomass and ecosystem function
Table 3
Results of model selection for zooplankton abundance in ecosystems with grazers (AG) and with grazers and predators (AGP). We used linear regressions (Methods: Statistical analysis). Models included terms for weekly average temperature (Twj), ecosystem trophic treatment (Zj) and their interaction, and a random effect for ecosystem identity. We modeled 120 observations in 20 groups (ecosystems). We compared models using likelihood ratios (LogLik), AICC, Akaike weights (w), and δAICC weights. NA indicates that the term was not included in the model.
