A generally accepted explanation for the co-existence of species in high diversity communities is one of the outstanding unresolved issues in ecology. Current hypotheses fail to satisfy in their generality; spatial implications are inadequately explored empirically, and the hypotheses are not testable within a common framework. Advances in spatial analysis and complex system modelling now make the search for a general explanation feasible. This project will parameterise and test the different co-existence hypotheses using spatial statistics, empirical/experimental studies of dispersal, recruitment, competition and herbivory, and spatially-explicit computer simulation models of community assemblage in species-rich Australian shrubland communities.

物种在高多样性群落中共存的普遍接受的解释是生态学中悬而未决的问题之一。目前的假设不能满足他们的一般性，空间的影响是不充分的经验探索，和假设是不可检验的一个共同的框架内。空间分析和复杂系统建模的进步现在使得寻找通用解释变得可行。该项目将参数化和测试不同的共存假设，使用空间统计，经验/实验研究的扩散，招聘，竞争和草食动物，和空间明确的计算机模拟模型的社区组合在物种丰富的澳大利亚灌木群落。
