研究了两种竞争物种和三种竞争物种在多维资源空间中的资源分配演化。资源分配的最佳模式是在所有其他物种位置的条件下，同时最大化每个物种相对于其自身生态位的适合度。可能的解决方案数量有限，其中一些可能同时是最优的。与2种模型的任何解相比，3种模型的一些解涉及沿更多资源轴的划分。研究结果与蜥蜴种群的资源分配现象有关。
The evolution of resource partitioning in a multidimensional resource space is studied for 2 and 3 competing species. Optimal patterns of resource partitioning are determined by simultaneously maximizing the fitness of each species with respect to its own niche position, conditional on the positions of all other species. There are only a finite number of possible solutions, and several of these may be optimal simultaneously. Some solutions of the 3 spp. model involve partitioning along more resource axes than any solutions of the 2-species model. The results are related to empirical resource partitioning phenomena in Anolis lizard populations.
