Table S1. Akaike’s Information Criterion (AIC) for mixed effects models of the potential influences on reproductive success, including endophyte status (E), nature of infection (n), habitat type (h), and year (y). Different (random) intercepts were estimated for each individual of each mother of each population and for each block. The Δ column depicts the difference between a model’s AIC and that of the best-fitting model. The 10 models with lowest AIC are presented, plus the null model and the complete model. Akaike's weight (we) for each model is also presented.

Figure S1. Relative importance of independent variables and interactions among them on the reproductive state of plants. The length of each bar is the sum of the Akaike weights of all models that included the predictor of interest, taking into account the number of models in which each predictor appears.

Table S2. Akaike’s Information Criterion (AIC) for mixed effects models of the potential influences on the presence of pseudo-viviparous panicles on reproductive plants, including endophyte status (E), nature of infection (n), habitat type (h), year (y), and number of seminiferous panicles (PA). Different (random) intercepts were estimated for each individual of each mother of each population and for each block. The Δ column depicts the difference between a model’s AIC and that of the best-fitting model. The 10 models with lowest AIC are presented, plus the null model and the complete model.
