Average per cent error between slopes of environmental distance–decay relationships (DDRs) from field surveys and slopes of environmental DDRs from simulated communities versus randomly drawn values of model parameters. Community similarity is based on the Bray–Curtis (a,b), Sørensen (c,d) and Canberra (e,f) metrics. Each point represents the result of a single model and is coloured according to the value of environmental filtering. Models with greater degrees of environmental filtering and lesser degrees of dormant death more closely approximated empirical DDRs to within 0% error.
