Abstract: Niche and neutral processes are the two most important hypotheses currently used to describe the distribution and abundances of species within ecosystems. We applied a novel statistical approach to simulated data generated with either niche or neutral models, to highlight the environmental conditions under which these hypotheses can be reliably differentiated – and, equally importantly, those conditions where they cannot. This study has fundamental importance for the ecology community, as it adds and develops an analytical component to the argument over whether niche or neutral processes can be differentiated using the sort of biological data typically collected from the field.
