社区是如何组织起来的？物种在生态位/资源空间中均匀分布的程度如何？是否存在功能相似的物种集群？如果是的话，这样的行会仅仅是消费物种和/或资源空间的自然差距的内在设计约束的结果吗？或者，行业协会结构是否可以作为减少扩散竞争的一种手段而发展？（公会可能是种间激烈竞争的竞技场，公会内部的相互作用很强，但不同公会成员之间的相互作用很弱。一个没有行会结构的共同体比一个有行会结构的共同体有更大的扩散竞争。）更多样化的社区是否比更简单的社区有更多的行会结构？行会结构对社区的聚集、结构和多样性有何影响？行会结构实际上可以通过属于不同行会的物种之间的间接影响所产生的竞争性互惠来促进多样性。
How are communities organized? To what extent are species evenly spread out in niche/resource space? Do clusters of functionally similar species exist? If so, are such guilds merely a result of built-in design constraints on consumer species and/or natural gaps in resource space? Or, can guild structure evolve as a means of reducing diffuse competition? (Guilds are presumably arenas of intense interspecific competition with strong interactions within guilds but weak interactions between members of different guilds. A community without guild structure would have greater diffuse competition than one with guild structure.) Do more diverse communities have more guild structure than simpler communities? What are the effects of guild structure on the assembly, structure and diversity of communities? Guild structure may actually foster diversity by means of competitive mutualisms arising from the indirect effects between species that belong to different guilds.
