Natural habitats are patchy in quality. in clonal plants, resource-acquiring structures often occupy sites that differ in quality. Clonal plants can display division of labour in resource-acquisition duties, manifested as local specialization by ramets, which enhances acquisition of each resource from sites of greatest abundance. Physiological integration can re-distribute resources internally from sites of acquisition to clone parts sited where the same resources are scarce. Recent research is showing that such specialization and resource sharing is a highly efficient strategy for acquiring resources and that it can result in considerably greater growth when resources are heterogeneously distributed than when the same quantity of resources is distributed homogeneously.
自然栖息地的质量参差不齐。在克隆植物中，获取资源的结构通常占据质量不同的位置。克隆植物可以在资源获取任务中表现出劳动分工，表现为分株的局部专业化，从而增强从最丰富的位置获取每种资源的能力。生理整合可以将资源从获取地内部重新分配到同种资源稀缺的克隆部分。最近的研究表明，这种专业化和资源共享是获取资源的一种非常有效的策略，当资源呈异质分布时，其生长速度明显快于资源均匀分布时。
