Published estimates of the immigration parameter I in rainforest tree communities, using Spatially Implicit Neutral Models (SINMs).

The corresponding 95% quantile dispersal distances, , 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 are calculated here for the case when the forest plots represent complete communities (i.e. sample size = community size in Figure 1). values have been rounded to the nearest metre.
