The Kunming-Montreal Global Biodiversity Framework requires that evolutionary histories of species should be considered in conservation planning. The phylogenetic structure of species assemblages quantifies species evolutionary histories and increasingly becomes an endeavour for ecologists. Understanding the geographic patterns of phylogenetic structure of species assemblages and their drivers can provide a fundamental reference for conservation planning. Although several theoretical hypotheses based on the effects of contemporary environment, historical climate change and evolutionary niche conservatism had been widely discussed in previous studies, the relative contributions of these hypotheses on phylogenetic structure of angiosperms, especially herbaceous species, remain debated.

欧亚大陆东部被子植物的系统发育模式及其决定因素


昆明-蒙特利尔全球生物多样性框架要求在保护规划中考虑物种的进化历史。物种组合的系统发育结构量化了物种进化历史，并日益成为生态学家的一项努力。了解物种组合系统发育结构的地理格局及其驱动因素可以为保护规划提供基础参考。尽管基于当代环境、历史气候变化和进化生态位保守主义的影响的一些理论假设在之前的研究中已被广泛讨论，但这些假设对被子植物，特别是草本物种的系统发育结构的相对贡献仍然存在争议。
