作者： LIU HongMei ZHANG XianChun chen zhiduan QIU YinLong State Key Laboratory of Systematic and Evolutionary Botany Institute of Botany Chinese Academy of Sciences Beijing 100093 China Graduate University of the Chinese Academy of Sciences Beijing 100039 China Department of Ecology and Evolutionary Biology University of Michigan Ann Arbor MI 48109-1048 USA

The taxonomic status of the Eastern Asia endemic Sorolepidium is controversial. Some authors accept it as member of the large diverse genus Polystichum, whereas others suggest that it is an independent genus separated from the later by the exindusiate sorus and the absence of aristate teeth at the pinnae margins. Here we infer phylogenetic relationship of Sorolepidium using DNA sequences of the chloro-plast rbcL gene. Phylogenies were inferred using maximum-parsimony, maximum-likelihood, and Bayesian inference methods. Molecular data establish that Sorolepidium is deeply nested within the large genus Polystichum and has a close relationship with P. duthiei and P. lachenense in the model-based analyses. The Kimura 2-parameter distances of the rbcL sequences between S. glaciale and P. duthiei and P. lachenense were 0.1 and 0.2%, respectively. Furthermore, S. glaciale differed from P. duthiei by a single nucleotide in their rbcL sequences. Close relationships between S. glaciale and P. duthiei and P. lachenense are also supported by the shared spore ornamentation with echinate fenes-trate folds.

Myrtama 是以它的词法怪癖在 1970 年代从 Myricaria elegans Royle 说出的一个类。自从它的开始，这个类和它的系统的位置的建立被争论了。它从 Tamaricaceae 的 10 种类的序列被报导，并且由 PAUP 4.0b8 和贝叶斯的推理分析了重建发展史。一个单身者它的树分别地从最大的吝啬和 MrBayes 分析被产生。分子的数据集合作为一个姐妹组作为 monophyletic 类，和 Myrtama 为 Tamarix 和 Myricaria 显示出强壮的支持到类 Myricaria。基于词法差别，一棵单个词法树也被产生，在哪个二个主要的系存在但是 Myrtama 是到 Tamarix，而非 Myricaria 的一个姐妹组。从 DNA 序列和 Myicaria elegans 应该被放进既不 Myricaria 也不 Tamarix，但是放在它的自己的 monotypic 类的词法人物支持的证据。

Establishment of a national park protection system in China,including the latest target proposed to protect at least 30%of the land area,calls for a comprehensive exploration of conservation priorities incorporating multiple diversity *** herein evaluate the spatial distribution of Chinese flowering plants from the perspectives of richness,uniqueness,vulnerability,and evolutionary history,by integrating three mega-phylogenies and comprehensive distribution *** detect significantly high consistency among hotspots of different diversity measures for Chinese flowering plants,suggesting that multiple facets of evolutionary diversity are concentrically distributed in *** legal protection to these areas is expected to maximize positive conservation *** propose two integrative diversity indices by incorporating three richness-based and three phylogeny-based measures,*** methods identify areas with high species richness,but the integrative phylogeny-based index also locates key areas with ancient and unique evolutionary histories(e.g.,Ailao-Wuliang Mts,Dabie Mts,Hainan rainforest,Karst area of Yunnan-Guizhou-Guangxi,Nanling Mts,and southeast coastal regions).Of all the diversity indices explored,phylogenetic endemism maximizes the incidental protection of other indices in most cases,emphasizing its significance for conservation ***,42 priority areas are identified by combining the 5%-criterion hotspots of two integrative indices and the minimum area to protect all threatened species *** priorities cover only 13.3%of China's land area,but host 97.1%of species richness(23,394/24,095),96.5%of endemic species(11,841/12,274),100%of threatened species(2,613/2,613),and 99.3%of phylogenetic diversity for flowering plants involved in this *** frameworks provide a solid scientific basis for national park planning in China.

Comparative approaches that examine floras with similar environments, but different diversity patterns, provide good opportunities to elucidate how uneven distributions of biodiversity were assembled. Eastern Asia(EA) and North America north of Mexico(NA; see definitions of EA and NA in Fig. S1 A) share similar geographical environments with comparable latitude, land area and climate,

当前气候变化和新冠疫情对我们的城市系统提出重大考验,韧性且健康将成为未来城市至关重要的功能特性。运用复杂适应系统理论(CAS)来规划、建设和管理城市,提升城市韧健水平,将会很好地维持这一特性。在对城市韧健内涵解读、概念辨析、文献综述的基础上,从城市系统环境韧健、城市系统结构韧健、城市系统要素韧健三个维度出发,通过修正式德尔菲法确定了影响城市韧健水平的关键因素。通过研究城市系统韧健公式和城市发展韧力指数,提出城市系统韧健模型,对模型进行分解后,提出五大城市系统韧健提升途径。结合提升机制,构建了一套城市系统强健策略体系,以达成城市韧健功能目标,最后应用到北京韧性城市纲要中进行案例分析和解读。建议以城市系统韧健评价为抓手,对城市的不同机遇与挑战提出情景式的韧健规划进行应对。

The paper introduces the classical ABC model of floral development and thereafter ABCD, ABCDE and quartet models, and presents achievements in the studies on floral evolution such as the improved understanding on the relationship of reproductive organs between gnetophytes and angiosperms, new results in perianth evolution and identified homology of floral organs between dicots and monocots. The evo-devo studies on plant taxa at different evolutionary levels are useful to better understanding the homology of floral organs, and to clarifying the mysteries of the origin and sub-sequent diversification of flowers.

自达尔文提出生命之树的概念以来,该领域的研究不仅帮助人们了解了生物的起源和类群间的亲缘关系,还极大地推动了生命科学相关学科的发展.然而,随着生命之树重建中越来越多冲突的发现,人们对生命之树的可靠性及其在其他学科中的应用产生了质疑.本文简要介绍了生命之树的概念及其发展历史.综述了由于(ⅰ)物种的绝灭和人类认知局限性导致的取样缺乏;(ⅱ)生物进化过程中存在的杂交/渐渗、不完全谱系分选、基因重复和丢失、基因水平转移等事件;(ⅲ)建树方法不能真实地模拟生物的进化过程等原因,不可能获得完全一致的生命之树.最后,展望了生命之树广阔的发展和应用前景,指出尽管现实中很难得到唯一的生命之树,但这并不影响生命之树强劲的生命力及其与其他学科的交叉整合.
