The corresponding 95% quantile dispersal distances, Inline graphic, are given under the assumption of pure dispersal limitation using the Gaussian and Cauchy kernels (see main text). A is the sample area in ha and Js corresponds to the sample size in number of individuals above 10 cm dbh. S indicates the respective species richness of the sample plots. Bold/normal values respectively denote the published/transformed parameter values of Hubbell's [2] migration rate m or the corresponding immigration parameter, I [21]. m/I and Inline graphic are calculated here for the case when the forest plots represent complete communities (i.e. sample size  =  community size in Figure 1). Inline graphic values have been rounded to the nearest metre.
