当代生态位理论是一个有用的框架，可以用来理解有机体如何相互作用以及如何与它们共享的环境相互作用。由Tilman的资源比率假说推广的图形表示法，有助于分析包括物种共存在内的复杂动力学模型的平衡结构。这一理论从一开始就主要应用于资源竞争。在这里，我们通过将Tilman的图形表示扩展到植物授粉网络的消费者资源动态分析中，将互惠关系整合到生态位理论中。我们用图形解释了以前通过数值模拟发现的定性现象，包括筑巢、适应性觅食和传粉者入侵对群落动态的影响。我们的图形化方法促进了利基和网络理论的统一，并深化了消费者-资源框架内不同类型互动的综合。
Contemporary niche theory is a useful framework for understanding how organisms interact with each other and with their shared environment. Its graphical representation, popularized by Tilman’s resource ratio hypothesis, facilitates analysis of the equilibrium structure of complex dynamical models, including species coexistence. This theory has been applied primarily to resource competition since its early beginnings. Here, we integrate mutualism into niche theory by expanding Tilman’s graphical representation to the analysis of consumer-resource dynamics of plant-pollinator networks. We graphically explain the qualitative phenomena previously found by numerical simulations, including the effects on community dynamics of nestedness, adaptive foraging, and pollinator invasions. Our graphical approach promotes the unification of niche and network theories and deepens the synthesis of different types of interactions within a consumer-resource framework.
