Relaxing the zero-sum assumption in neutral biodiversity theory.
The zero-sum assumption is one of the ingredients of the standard neutral model of biodiversity by Hubbell. It states that the community is saturated all the time, which in this model means that the total number of individuals in the community is constant over time, and therefore introduces a coupling between species abundances. It was shown recently that a neutral model with independent specie...
متن کاملNon-neutral theory of biodiversity
We present a non-neutral stochastic model for the dynamics taking place in a metacommunity ecosystems in presence of migration. The model provides a framework for describing the emergence of multiple ecological scenarios and behaves in two extreme limits either as the unified neutral theory of biodiversity or as the Bak-Sneppen model. Interestingly, the model shows a condensation phase transiti...
متن کاملParasites and the neutral theory of biodiversity
At a time when biodiversity is under threat from human encroachment upon, and destruction of, natural habitats, we are in a dire need of a theory of biodiversity that integrates what we know of the processes responsible for the origin and maintenance of species diversity in a predictive framework. Hubbell (2001) proposes such a theory, analogous to the neutral allele theory of molecular evoluti...

متن کاملA Unified Theory of Zero - Sum Problems
Abstract. In combinatorial number theory, zero-sum problems, subset sums and covers of the integers are three different topics initiated by P. Erdős and investigated by many researchers; they play important roles in both number theory and combinatorics. In this paper we reveal some deep connections among these seemingly unrelated fascinating areas, and establish a unified theory for the first t...
