    "abstract": "An analytical approximation is derived for the Zero Sum Multinomial\ndistribution which gives the Species Abundance Distribution in Neutral\nCommunity Models. The obtained distribution function describes well computer\nsimulation results on the model, and leads to an interesting relation between\nthe total number of individuals, total number of species and the size of the\nmost abundant species of the considered metacommunity. Computer simulations on\nneutral community models, proves also the validity of this scaling relation.",
