摘要: 植物群落邻体间的系统发育关系是密度制约的重要预测因子,但在不同研究结论中邻体间系统发育关系对邻体效应的影响不一致。该文基于Web of Science、Google Scholar和CNKI三个数据库,通过关键词检索邻体间系统发育关系对邻体效应的影响的相关文献(1980.01.01~2022.05.01),对标题、摘要和全文进行筛选,纳入分析文献35篇。邻体间系统发育关系对邻体效应的影响有三种:系统发育负密度制约效应(PNDD)、系统发育正密度制约效应(PPDD)和无系统发育密度制约,其文献篇数依次递减。PNDD主要受资源竞争、天敌和病原体的影响;PPDD与共生真菌、生境异质性小和生境过滤相关;而植物早期邻体间无直接的相互作用和性状无系统发育信号会导致无系统发育密度制约。邻体间系统发育密度制约结论不一致主要是因为不同研究地点的环境异质性、研究方法、尺度和研究对象的不同。因此,在探究邻体间系统发育对邻体效应的影响时,应尽可能考虑这些因素的影响。

Abstract: Phylogenetic relationships among neighbors are significant predictors of density dependence in plant communities. However, there is no consistent conclusion about the effect of phylogenetic density dependence . We conducted a comprehensive literature search for the effect of phylogenetic density dependence using the Web of Science, Google Scholar and CNKI by keywords from 1 January 1980 to 1 May 2022. We screened titles, abstracts and full texts of the papers, and 35 publications were selected. The strength of the influence of phylogenetic distance on the interactions between neighboring trees in each study was extracted. There are three effects of phylogenetic relationships on neighborhood effects: phylogenetic negative density dependence (PNDD), phylogenetic positive density dependence (PPDD) and no phylogenetic density dependence, the numbers of whose articles decrease in turn. PNDD was mainly caused by associated competition resources, natural enemies and host-specific pathogens. PPDD was associated with small habitat heterogeneity, habitat filtering and symbiosis with mycorrhizal fungi. However, there are no phylogenetic density dependence due to absence of phylogenetic signal in functional traits and no direct interaction between early plant neighbors. The main reasons for the different results caused by various environmental heterogeneities, research scales, study types, target species and the life history stages of plants in different studies. Therefore, the influence of these factors should be considered as far as possible in the study of phylogenetic density dependence in the future.
