Hi!,

I am processing my data about the effects of combining two stressors on growth rates, mortality, survival, etc of aquatic insects. I used in some cases GLM models. I am quite confuse about on how interpret the results in the model (antagonist, synergistic or additive effects). For example, in one GLM my results suggested me that the best candidate model was the one without the interaction of the stressors. Is that meant that there are not (antagonist, synergistic, additive) response of the stressors?. OR maybe I need to applied other type of analysis?. Thanks for your answers.
