A summary of results from randomization tests.

The table displays the number (out of 12) of ex-arable field sites that had non-random assembly of a given trait. Species assembly between the regional species pool (regional pool) and the local propagule pool (propagule pool), local seed rain and local seed bank were explored as well as the assembly between the local propagule pool and the local community. The traits used were species abundance in the regional species pool (Abundance), mean height, seed mass, specific leaf area (SLA), clonal growth index (CGI) and dispersal method. The statistics were mean trait values (mean values), standard deviation of the nearest trait distance (sdNTD), site trait variance (variance). Mean trait values and site trait variance for assembly from the regional species pool were both calculated where species were chosen at random from the regional species pool into the local propagule pool/seed rain and seed bank (EP) and where the probability of species to be chosen was linked to the species abundance in the regional species pool (WP). For dispersal method the number represent sites with higher proportion of unassisted dispersal than expected from a random assemble. – in front of a number indicate trait convergence, + indicates trait divergence. NA represent associations not explored.
