摘要

物种之间成对的相互作用会被群落中的其他成员所改变,从而产生取决于群落组成的新动态。尽管这种高阶相互作用非常普遍,但人们对它们如何与物种到达的时间和顺序相关联却知之甚少。我们通过一个植物-土壤机械反馈模型生成种群动态,然后应用一般理论框架证明,第三种植物对成对相互作用的改变取决于其发芽物候。植物和微生物种群的同时变化会导致这些随时间变化的相互作用的改变,而植物相关微生物群之间更高的重叠度会加强这种改变。这种重叠与微生物群特异性之间的相互作用进一步决定了植物的共存。我们的框架广泛适用于其他系统中的机制,这些机制也会产生类似的随时间变化的相互作用变化,这突出表明有必要整合物种相互作用的时间变化,以预测自然群落的突发动态。

Time-dependent interaction modification generated from plant–soil feedback

Time-dependent interaction modification generated from plant–soil feedback

Pairwise interactions between species can be modified by other community members, leading to emergent dynamics contingent on community composition. Despite the prevalence of such higher-order interactions, little is known about how they are linked to the timing and order of species' arrival. We generate population dynamics from a mechanistic plant–soil feedback model, then apply a general theoretical framework to show that the modification of a pairwise interaction by a third plant depends on its germination phenology. These time-dependent interaction modifications emerge from concurrent changes in plant and microbe populations and are strengthened by higher overlap between plants' associated microbiomes. The interaction between this overlap and the specificity of microbiomes further determines plant coexistence. Our framework is widely applicable to mechanisms in other systems from which similar time-dependent interaction modifications can emerge, highlighting the need to integrate temporal shifts of species interactions to predict the emergent dynamics of natural communities.

期刊介绍: Ecology Letters serves as a platform for the rapid publication of innovative research in ecology. It considers manuscripts across all taxa, biomes, and geographic regions, prioritizing papers that investigate clearly stated hypotheses. The journal publishes concise papers of high originality and general interest, contributing to new developments in ecology. Purely descriptive papers and those that only confirm or extend previous results are discouraged.
