study of the issue indicates that it is not a serious problem for neutral theory, reasons we discuss below. First, bit background. Hubbell (2001) derived analytical expression stochastic mean and variance abundance single arbitrary species in community undergoing immigration from metacommunity source area. However, his approach did lend itself to an solution distribution relative (RSA) multispecies sizes larger than handful individuals. As result, all Hubbell's RSA distributions local communities were based on simulations. This was solved by Volkov et al. (2003), who size. as Chisholm Burgman noted, there sometimes difference between some simulation-based results (2003). computed Volkov's equation resimulated four cases
