摘要
自然环境中的资源通常呈现出异质性分布模式。克隆植物在应对不均匀分布的资源时,能够有选择地放置其新生分株来实现对新生境的占领,以此提高整个基株的适应能力和竞争力,从而有效地利用斑块状分布的资源。此外,克隆植物在维持群落生产力和稳定性方面也发挥着关键作用。近年来,对异质性资源环境中克隆植物的生境选择研究备受关注。在介绍生境选择和觅食行为的基础上,从克隆植物养分吸收结构的选择性放置、生长构型和生物量分配模式3方面阐述了克隆植物生境选择行为的表现和方式,并从克隆植物如何感知周围环境信息、克隆整合是否影响植物生境选择以及表观遗传记忆对生境选择行为的调控等方面,对相关领域主要的研究进行综述和探讨,并提出了克隆植物生境选择研究中值得关注的方向,希望能够为深入理解植物的生境选择行为提供一个新的视角。
In natural ecosystems,the essential resources usually exhibit heterogeneous distribution pattern.Clonal plants can effectively utilize the patchy distribution of resources by selectively placing their new offspring ramets to occupy new habitats,thereby enhancing the adaptability of the entire clone and consequently increasing its competitiveness.Additionally,clonal plants are crucial in maintaining community productivity and stability.Therefore,in recent years,researchers have paid a lot of attention to studies on habitat selection by clonal plants in heterogeneous resource environments.This review,building upon the fundamentals of habitat selection and foraging behavior,elaborates on the performance and patterns of clonal plant habitat selection from three perspectives:The selective placement of nutrient-absorbing structures,growth patterns,and biomass allocation.The review encompasses recent studies in the field,addressing how clonal plants perceive environmental information,the mechanisms through which clonal integration influences plant habitat selection,and the regulation of habitat selection behavior by epigenetic memory.Also,explores and suggests promising directions for further research in clonal plant habitat selection,aiming to provide a new perspective for a comprehensive understanding of plant habitat selection behavior.
