摘要
真菌是真核生物中生物多样性最丰富的类群之一,广泛分布于自然界,在生物多样性的分布与维持、群落构建以及物质与能量循环过程中发挥着重要的生态功能。近年来随着DNA高通量测序技术和生物信息学的发展,极大推动了真菌多样性分布格局与群落构建机制的研究进展。本文概述了基于生态位理论(niche theory)和中性理论(neutral theory)的选择(selection)、扩散(dispersal)、成种(speciation)和漂变(drift)等过程与生态模型的定量分析确定性过程和随机性过程对群落构建贡献的机制,及其在真菌群落构建中应用的最新研究进展。
Fungi,as an important component of the most abundant eukaryotes,widely distribute in nature and play important functions in biodiversity distribution pattern and maintenance,community assembly,and material circulation and energy flow in ecosystems.With recent development of the DNA high through-put sequencing techniques and bioinformatics,researches on diversity distribution patterns and community assembly of fungi have been greatly advanced.This paper reviews community assembly mechanisms of the selection,dispersal,speciation and drift processes based on niche theory and neutral theory and quantitative contribution of determinism and stochasticity of ecological models,and their use in recent studies on fungal community assembly.
