Beijing, the capital city of China, is one of the largest and most rapidly-urbanizing cities in the world. In this work, we present the main results of one decade’s research on urban vegetation and plant diversity changes in different urban structural units. Urban vegetation/plant diversity has been studied at two different levels: at the landscape level (greening percentage, fragmentation degree) and at the plant species level (structure, composition, and origin). Finally, concerns with the ability to study Beijing’s plant urban ecology are discussed.
北京是中国的首都,是世界上最大、城市化速度最快的城市之一。在这项工作中,我们介绍了十年来不同城市结构单元的城市植被和植物多样性变化研究的主要成果。城市植被/植物多样性在景观水平(绿化百分比、破碎化程度)和植物物种水平(结构、组成和来源)两个不同的层面进行了研究。最后,对北京植物城市生态研究能力的问题进行了探讨。

The mountain areas in south-central China are widely recognized as refugia of relict plants during the late Neogene and Quaternary periods. In this paper, we try to explore the distribution patterns of natural habitats and to exactly locate the refugia of relict species around Fanjingshan Mountain using dendrological data of long-lived individuals (≥ 100 years old). Six typical relict plants were found around the mountain, i.e. Cyclocarya paliurus, Ginkgo biloba, Liriodendron chinense, Pinus massoniana, Podocarpus macrophyllus , and Taxus chinensis . The long-lived individuals were divided into three classes according to their ages: Class-I (≥ 500 years), Class-II (300–499 years), and Class-III (100–299 years). Our results showed that the south-west region to the mountain was the main distribution area of Class-I trees of G. biloba and T. chinensis , most of which occurring in the same small village (Yangliu Village of Yinjiang County). The north-east region harboured all the six relict species. Floristic analyses also indicated these two regions were very similar in tree growth as measured by DBH (diameter at breast height of 1.3 m). Thus, these two areas would have provided long-term suitable habitats for relict species. The south-west region, especially the small village Yangliu, should be given highest priority for in situ conservation of relict species and other rare and endangered plants. Attention should also be paid to the north-east region for its very high species diversity of relict species.
中国中南部山区是新近纪晚期和第四纪时期公认的植物遗存区。本文试图利用长寿个体(≥100岁)的树木学资料,探索梵净山周边自然生境的分布格局,并对遗存物种的避难所进行准确定位。在山周围发现了6种典型的遗存植物,分别是环柏、银杏、鹅尾楸、马尾松、大叶竹和红豆杉。将长寿个体按年龄分为三类:ⅰ类(≥500岁)、ⅱ类(300 ~ 499岁)和ⅲ类(100 ~ 299岁)。结果表明,西南至山区是两种树种的主要分布区域,且大部分分布在同一小村(阴江县杨柳村)。东北地区保存了所有6个遗存物种。植物区系分析还表明,以胸径(胸径1.3 m)衡量,这两个地区的树木生长非常相似,因此,这两个地区可能为遗存物种提供了长期的适宜栖息地。在西南地区,特别是杨柳小村,应优先考虑对遗存物种和其他珍稀濒危植物进行就地保护。东北地区的遗种多样性也非常高,值得重视。

In late 2014 the Botanic Institute of Barcelona (IBB) received great news regarding the Salvador Collection kept in the center. On December 19, 2014, the Official Gazette of the Government of Catalonia published the recognition of the Salvador Cabinet as a “Heritage of Cultural Interest” (Be Cultural d’Interes Nacional–BCIN) (DOGC, 2014), the maximum level protection provided by the Catalan government to safeguard public heritage. Two months later, on February 5, 2015, this recognition was also published in the Official Gazette of the Government of Spain (BOE, 2014). The declaration of this collection as BCIN responds to the need to protect and disseminate a really valuable and outstanding part of the Catalonian heritage.

Some questions related to the nomenclature of Phlomis × composita Pau (Lamiaceae) are precised. The name P. × composita is typified based on the original material from Pau, collected by Bourgeau in 1849 and preserved in the herbarium of the Real Jardin Botanico de Madrid (Spain). A previous type proposed by Mateu (1986) is rejected for being incorrect. A new taxonomical status is proposed for the hybrid between P. crinita Cav. subsp. crinita and P. lychnitis L. (Lamiaceae) under the range of nothosubspecies: P. × composita nothosubsp. trullenquei (Pau) P. P. Ferrer, Guara & E. Laguna, stat. nov.

T axonomical and nomencla T ural no T es on Centaurea : a proposal of classifica T ion , a descrip T ion of new sec T ions and subsec T ions , and a species lis T of a redefined sec T ion Centaurea .— In this paper, we summarize the results of our long-date research on the genus Centaurea. The first part of the paper deals with the overall classification of the genus, which we propose to divide into three subgenera: subgenus Centaurea, subgenus Cyanus and subgenus Lopholoma. The second part of this publication gives a recopilation of the species of the redefined section Centaurea, a group that includes former sections Acrolophus (sect. Centaurea s. str.), Phalolepis and Willkommia, together with taxonomical, geographical, ecological and karyological considerations . Finally, new descriptions or nomenclatural combinations are proposed to correlate nomenclature to the new classification: a new combination (sect. Acrocentron subsect. Chamaecyanus) is proposed in subgenus Lopholoma; three new sections (sects. Akamantis, Cnicus, and Hyerapolitanae) are described in subgenus Centaurea; two subsections (subsects. Phalolepis and Willkommia) in sect. Centaurea; and three subsections (subsects. Exarata, Jacea, and Subtilis ) in sect. Phrygia.

Linum mucronatum is a heterostylous species from sect. Syllinum with four subspecies in Iran. The present study examines palynological characteristics of the heterostylous subspecies of Linum mucronatum , pollen characters of brevistylous individuals (pins) as well as longistylous individuals (thrums) of these plants by scanning electron microscope and light microscope using the prolonged acetolysis procedure. Sixteen qualitative and quantitative characters were investigated. Pollen equatorial shapes varied between pin and thrum individuals of each subspecies with the exception of L. mucronatum subsp. assyriacum . Pollen sculptures varied between pin and thrum samples of each subspecies and were seen in the gemmate, clavate and baculate shapes. In addition, quantitative palynological characters differed between plants and ANOVA test showed significant variations for traits such as equatorial length, colpi width and apocolpium diameter. Hetrostylous individuals of each subspecies were separated from others in the UPGMA tree and also in the PCO and PCA plots. This study confirmed variations in pollen features between pin and thrum individuals of each subspecies.

Ecological palaeoecology: a missing link between ecology and evolution 生态古生态学:生态学与进化之间缺失的一环
Q3 Agricultural and Biological Sciences Pub Date : 2014-12-30 DOI: 10.3989/COLLECTBOT.2013.V33.005
V. Rull
Palaeoecology is more than a palaeoenvironmental discipline; it is a science that is well-suited for supplying the empirical evidence necessary to test ecological hypotheses and contributes to our understanding of the interface of ecology and evolution. A critical time frame in palaeoecology is the often-overlooked Q-time dimension (centuries to millennia), which tends to be the most appropriate time dimension to examine ecology–evolution interactions. This paper discusses these topics from a conceptual perspective and provides examples of the contributions of palaeoecology to the study of ecology–evolution interactions. It also admonishes researchers about the threats of overlooking palaeoecology. Specifically, this paper argues that the neglect of palaeoecology may result in the loss of empirical support for ecology and its interactions with evolution as DNA-based phylogenetic and phylogeographic studies become more and more prevalent. The main concepts discussed are the time continuum, the notion of ecological palaeoecology and the empirical nature of palaeoecology in the face of more hypothetical approaches. More practically speaking, several examples are provided that highlight the utility of ecological palaeoecology for understanding a variety of processes, including ecological succession, community– environment equilibria, community assembly, biotic responses to environmental change, speciation and extinction, and biodiversity conservation. The ecology–evolution interface is analysed using two processes in which these disciplines interact intensively: ecological succession and long-range migration. This work concludes that both ecological palaeoecology (including ancient DNA records) and DNA-based phylogenetics and phylogeography are needed to better understand the biosphere ecologically and the processes occurring at the ecology–evolution interface.
古生态学不仅仅是一门古环境学科;这门科学非常适合为检验生态学假说提供必要的经验证据,并有助于我们理解生态学和进化的界面。在古生态学中,一个关键的时间框架是经常被忽视的q时间维度(几百年到几千年),它往往是研究生态-进化相互作用的最合适的时间维度。本文从概念的角度讨论了这些问题,并举例说明了古生态学对生态-进化相互作用研究的贡献。它还告诫研究人员忽视古生态学的威胁。具体而言,本文认为,随着基于dna的系统发育和系统地理研究越来越流行,对古生态学的忽视可能导致生态学及其与进化相互作用的经验支持的丧失。讨论的主要概念是时间连续体,生态古生态学的概念和面对更多假设方法的古生态学的经验性质。更实际地说,提供了几个例子,突出了生态古生态学在理解各种过程中的效用,包括生态演替,群落-环境平衡,群落组装,生物对环境变化的响应,物种形成和灭绝,以及生物多样性保护。生态-进化界面分析使用两个过程,其中这些学科相互作用密切:生态演替和远程迁移。本研究认为,生态古生态学(包括古DNA记录)和基于DNA的系统发育学和系统地理学都是更好地理解生物圈生态和发生在生态-进化界面的过程的必要条件。

A critical time frame in palaeoecology is the often-overlooked Q-time dimension (centuries to millennia), which tends to be the most appropriate time dimension to examine ecology–evolution interactions. This paper discusses these topics from a conceptual perspective and provides examples of the contributions of palaeoecology to the study of ecology–evolution interactions. It also admonishes researchers about the threats of overlooking palaeoecology.
