Table 2.

The estimated posterior median values for regression and variance parameters at the community level. For the parameters describing the effect of treatments and spore traits, we show also the posterior probability (%) that the effect is positive or negative (denoted P_post (β_x ≠ 0); calculated based on a sample of 10,000 values from the posterior distribution), corresponding to the sign of the median. See equations (1–2) in Modelling the effect of spore characteristics on viability for the model equations
