摘要:
In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field. © 2020 Informa UK Limited, trading as Taylor & Francis Group.

摘要:
Introduction. Human disturbance has recently led to increasingly serious destruction of Sphagnum L. wetlands in subtropical high mountains, resulting in an urgent need for wetland restoration. Methods. Through a field experiment conducted in western Hubei Province, China, the effects of four different microtopographic types [concave surface, convex surface, concave and convex surface (CC surface), and flat surface] and water table depth (0 to -30 cm) on three growth indicators (number of capitula, coverage and biomass) of Sphagnum palustre L. were examined. The objective was to identify the optimal hydrological conditions for S. palustre growth and thus facilitate its rapid recolonisation and restoration of these wetlands. Key results. The results showed that different microtopographic conditions significantly influenced S. palustre growth. Among them, S. palustre in the CC surface showed the worst growth, while no significant differences existed among the other three microtopographic types. Additionally, as the water table increased, the growth of S. palustre increased, but long-term flooding impeded growth. The water table affected S. palustre growth via effects on its tissue water content. Conclusions. Microtopographic reshaping was not essential for the success of S. palustre recolonisation, and microtopography that maintained the water table to within -10 cm of the surface without flooding were best, independent of the microtopographic types. In addition, the growth patterns of S. palustre changed with changes in the environment, which may be related to its long-term adaptation to conditions of a lower water table.

摘要:
Sphagnum wetlands in subtropical high-mountain regions have been severely destroyed by human activities, necessitating restoration efforts. We studied the effects of substrate and planting method on Sphagnum palustre L. growth and the underlying mechanisms to determine the optimal conditions for S. palustre restoration. S. palustre collected from natural wetlands was grown on nine substrates and with four planting methods in a greenhouse. The results show that S. palustre grew best in mountain yellow-brown soil without added peat or river sand and when planted as intact plants. Substrate pH and P content and capitula P content negatively correlated with S. palustre productivity, while initial biomass of S. palustre at planting positively correlated with productivity. S. palustre restoration on local mountain soil in subtropical high-mountain regions is practical, which may provide a new perspective for restoring peatlands. Traditional restoration method using the 10 cm upper parts of S. palustre as transplanted materials does not destroy the source S. palustre populations in habitats where plants are collected. However, we argue that a planting method using only capitula (top 1-2 cm) may be a better choice for S. palustre restoration, due to the similar productivity but less impact to source S. palustre populations.

摘要:
Human activities have recently caused severe destruction of Sphagnum wetlands in subtropical high-mountain regions, calling for urgent efforts to restore Sphagnum wetlands. Through a greenhouse experiment in western Hubei, China, we studied the effects of different substrate types (peat and mountain soil) and different levels of nitrogen (N) (0, 2, 4, 6, 10 g m −2 year −1 ) and phosphorus (P) (0, 0.2, 0.5, 1, 2 g m −2 year −1 ) on the growth of Sphagnum palustre, which was evaluated by four growth indicators: length growth, number of capitula, coverage change and biomass. We aimed to determine the optimal nutrient conditions for S. palustre growth, which would contribute to the rapid colonization and restoration of Sphagnum wetlands. The results showed that the different substrates significantly influenced S. palustre growth. Compared with those of peat, the acidic properties of the local yellow brown soil in the subtropical high-mountain regions were more favorable for S. palustre growth. As N addition increased, the four growth indicators responded inconsistently to the different substrates. While the number of capitula markedly increased, the other three indicators significantly decreased in the mountain soil or exhibited no definitive changes in the peat. The addition of P markedly promoted S. palustre growth in both substrates. However, a threshold for P fertilization existed; the highest productivity occurred at P additions of 0.2 and 0.5 g m −2 year −1 in the peat and mountain soil, respectively. The N and P contents in the capitula increased in parallel as the N and P fertilization rates increased, suggesting that these nutrients were absorbed proportionately and were used during the growth of S. palustre. © 2018, Springer Science+Business Media B.V., part of Springer Nature.

摘要:
Vegetation of Sphagnum moss wetlands in the Qi Zimei Mountains was surveyed by phytosociological methods (Braun-Blanquet, Pflanzensoziologie, Grundzuge der Vegetationskunde, vol 3. Springer, p 631, 1964) in May and July 2012. Results show that there are 67 families, 128 genera and 196 species (including varieties) of higher plants. Among them, there are 2 families, 2 genera and 2 species of bryophytes, 6 families, 7 genera and 8 species of pteridophytes, 59 families, 119 genera and 186 species of spermatophytes. Rosaceae exhibits the highest richness, with 25 plant species in total. Vegetation of Sphagnum wetlands in Qi Zimei Mountains was classified into eight associations: (1) Assn. Juncus setchuensis + Carex taliensis–Sphagnum palustre ssp. palustre (2) Assn. Juncus setchuensis + Lycopus coreanus var. cavaleriei–Sphagnum palustre ssp. palustre (3) Assn. Carex taliensis–Sphagnum palustre ssp. palustre (4) Assn. Polygonum thunbergii–Sphagnum palustre ssp. palustre (5) Assn. Malus hupehensis–Carex filicina var. meiogyna–Sphagnum palustre ssp. palustre (6) Assn. Rhododendron auriculatum–Pteridium aquilinum var. latiusculum–Sphagnum palustre ssp. Palustre (7) Assn. Acorus calamus–Sphagnum palustre ssp. palustre (8) Assn. Enkianthus chinesis–Sinarundinaria nitida–Carex taliensis–Sphagnum palustre ssp. palustre. The appearance of the vegetation types vary across seasons. Further research on biodiversity and ecological restoration of Sphagnum mire in western Hubei Province is ongoing. © 2018, Springer International Publishing AG, part of Springer Nature.

摘要:
为有效挖掘湖北神农架核桃(Juglans regia)的种质资源,采用12对多态性高的SSR分子标记引物对3个神农架核桃居群90个单株的遗传多样性及其种群内、种群间的遗传分化进行研究。结果表明:用12对针对核桃属植物基因组设计的SSR引物共检测到108条谱带,其中多态带占比为100%。遗传多样性分析结果显示:居群总期望杂合度为0.604,其遗传多样性水平较高,很可能蕴含了稀有基因资源。遗传分化系数(Fst)显示:有8.22%的变异存在于3个居群间,遗传分化程度中等。这可能与3个居群的地理距离远有关。部分位点显示出居群总体有杂合不足的现象。聚类分析结果显示:居群之间的遗传距离与地理距离具有较高的一致性。

摘要:
Based on sequences of ITS, matK, rbcL and rps16, a phylogenetic tree is constructed for Pseudostellaria and outgroup genera of Caryophyllaceae subfamily Alsinoideae including Stellaria and Cerastium, and members of subfamily Caryophylloideae, by means of maximum parsimony, maximum likelihood and Bayesian inference. The results indicate that core Pseudostellaria is monophyletic; however, the presence of two recognizable clades in the genus does not support the current infrageneric classification into two sections. Evolution of six morphological characters, including root tubers, stamen number and cleistogamous and chasmogamous flowers, reflect phylogenetic relationships between Pseudostellaria and allied taxa. The three North American Pseudostellaria spp. fell outside of the genus; Pseudostellaria sierrae and Pseudostellaria oxyphylla formed a well-supported clade, and they are treated as a new genus, Hartmaniella.

摘要:
Zelkova, a relic of the Cenozoic, is an element of Northern Hemisphere woodlands. We sequenced and combined ITS and trnL-trnF, psbA-trnH, and rbcL to reconstruct a phylogenetic tree. The result shows that there are two geographical groups, East Asia and western Asia–southern Europe appeared within Zelkova. The age of Zelkova was traced to Cretaceous ca. 70 Ma, the crown divergence age of the Ulmaceae. Generic diversification was started at Paleocene ca. 53 Ma. Based on the reconstructed ancestral area, northeastern China was speculated to be the place of origin, from where species migrated westward to western Asia–southern Europe and dispersed to Japan and Korea within East Asia. East Asia, especially the Chinese subtropical region, was presumed to be the diversity center. The historical and ecological causes of the Zelkova distribution pattern are presumed to relate to the East Asian monsoon onset at about 22 Ma as well as the Qinghai–Tibetan Plateau uplift. Species extinction in northeastern China perhaps coupled with the climate cooling event, the glacial epoch during the Quaternary. © 2017, Springer-Verlag GmbH Germany.

摘要:
针对神农架川金丝猴生境基础研究中乔木树种大范围分布数据难以获取问题,尝试利用多源多时相遥感数据结合专家知识分层次实现树种识别。首先采用冬季Landsat8 /OLI数据根据物侯特性分层提取常绿、落叶林的地域范围;进而依据夏季Worldview-2高分遥感影像的实地乔木样本的光谱特征分层次完成常绿树种(巴山冷杉、华山松、青$、刺叶栎)和落叶树种(红桦、日本落叶松、米心水青冈、漆树、锐齿槲栎、椅杨)的识别;并通过实地植被样方及专家知识通过高程数据完成分类结果的修正;最后结合GIS对主要优势树种的地形及地域分布特征进行了空间分析。实验精度表明常绿林中巴山冷杉、华山松、刺叶栎、虫害华山松整体精度较高,落叶林中红桦、漆树等识别精度相对较高,部分树种如椅杨、锐齿槲栎识别精度较低;总体上常绿树种的精度要优于落叶树种。从植物地理学、遥感、GIS三者相结合的角度,将多源、多时相遥感数据与物种物候特性、专家知识进行有效整合,提出了一种乔木树种识别的方法(1)提供了复杂山地环境的主要乔木优势种识别途径,且具有通用性;(2)完成了物种物候特性与遥感数据特性的整合利用,有效降低数据成本费用;(3)配合地面样方及专家知识修正结果,避免了过分依赖光谱特征引起的误判。这将为神农架川金丝猴栖息地保护与恢复提供更精确的数据依据。

摘要:
为了解鄂西北地区的鱼类多样性和鱼类群落结构,于2007~2012年先后对鄂西的八卦山自然保护区、堵河源自然保护区、五道峡自然保护区、南河自然保护区、野人谷自然保护区及漳河源自然保护区的鱼类资源进行调查。结果显示, 6个自然保护区共有鱼类79种,隶属4目15科51属。鲤形目鱼类为6个自然保护区的主要类群,共56种,占总数的70.89%。 6个自然保护区的鱼类食性和生态类群相似,鱼类食性均以肉食性和杂食性为主,草食性鱼类较少;定居性鱼类占主体,河湖洄游性和喜流水性鱼类较少。渔获物分析表明,堵河源自然保护区鱼类丰富度指数(D)最大,为2.60,八卦山自然保护区鱼类丰富度指数最小,为0.91。多样性分析表明,同一水系的保护区之间的βc值和β_R值均比处于不同水系的保护区之间的βc值和β_R值小;处于同一水系的保护区相似性系数(C_j)较高,处于不同水系的保护区之间的相似性系数较低(C_j),这很好的诠释了处于同一水系的自然保护区在地理环境上的连续性,而处于不同水系的自然保护区之间出现了地理环境的分化隔离。目前水电开发和过度捕捞是该地区鱼类最大的威胁因子,建议强化渔政管理,并建立鱼类人工繁育基地,以减缓水电工程带来的不利影响,恢复天然渔业资源。

摘要:
以鄂西七姊妹山泥炭藓湿地QZMS钻孔沉积物为研究对象,通过AMS14C测年、岩性特征与沉积物粒度综合分析,探讨了鄂西南山地13 000 cal.a BP以来的沉积环境变迁.研究结果显示:QZMS钻孔沉积物粒度组成主要以细粉砂和中粉砂为主,频率分布曲线均为单峰分布,由下至上,峰度由宽到窄,偏度从近于对称到正偏,揭示了搬运动力和沉积环境的演变过程;综合分析结果表明研究区沉积环境演化可分为4个阶段:1)12.9~11.6 cal.ka BP,气候波动频率高,但幅度较小,水动力条件相对较弱;2)11.6~10.2 cal.ka BP为晚更新世向全新世的过渡阶段,水动力条件持续较弱,环境相对稳定;3)10.2~7.7 ca1.ka BP早全新世,气候变得暖湿,水动力条件较前一阶段有所增强,泥炭藓湿地开始形成;4)7.7~2.0 cal.ka BP气候暖湿,水动力条件达到最强,峰度和偏度波动频率低,但幅度增大,为沼泽湿地环境.研究表明七姊妹山泥炭藓湿地沉积物的粒度粗细与区域内水文条件和物源的变化密切相关,借助粒度组成和参数特征,可反演该区域的沉积环境演变,揭示泥炭藓湿地发育形成的过程,为该地区泥炭藓湿地的保护和气候环境变化研究提供科学参考.

地形;物种丰富度;物种分布;典型对应分析;七姊妹山自然保护区
摘要:
该研究以七姊妹山自然保护区40个(20×20 m~2)植物群落调查样方为基础,并采用回归分析和典型对应分析(CCA)的方法研究该区地形对植物物种丰富度及植物分布格局的影响,以明确海拔、坡度、坡向、坡位等地形因子的相对重要性,为该区植物多样性的保护和管理提供理论依据。结果表明:(1)七姊妹山自然保护区40个调查样地共有植物633种,隶属133科,316属,其中乔木118种,灌木150种,草本365种。(2)曲线回归方程拟合结果显示,七姊妹山自然保护区植物物种丰富度分别与海拔、坡度具有显著相关性,物种丰富度沿海拔梯度升高而增大,沿坡度梯度先减少后增大之后又减小。(3)从植物的生活型来看,在所有海拔段,乔木物种丰富度始终低于灌木和草本植物;在低、中低海拔地带,灌木物种丰富度均高于乔木和草本植物;而在中、高海拔地带草本植物物种丰富度较大且高于乔木和灌木。(4)CCA排序结果表明,地形因子对植物物种的分布具有显著影响按其影响强度排序为海拔 >坡度>坡位 >坡向,说明海拔是影响该区植物物种分布最重要的地形因子。

摘要:
在标本和文献综合分析的基础上,对世界范围内孩儿参属(Pseudostellaria Pax)植物的主要形态特征进行了总结,依据Mizushima的分类系统编制了孩儿参属的分类检索表,对5个存疑种进行了初步分类处理,并对孩儿参属各种类的分布状况进行了绘图和分析。结果表明:具有肉质块根、绝大多数种具有闭锁花以及开放花花瓣常呈2浅裂是孩儿参属区别于石竹科(Caryophyllaceae)其他属的典型特征。初步确认全世界的孩儿参属植物共22种,被分成Sect. Pseudostellaria和Sect. Mamillatae2个组,其中,前者仅包含石生孩儿参[P. rupestris (Turcz.) Pax]1种,而后者则被进一步分成Ser. Mamillatae和Ser. Distantes2个系。本研究结果不支持将P. sierrae Rabeler et R. L. Hartm.和P. oxyphylla (B. L. Rob.) R. L. Hartm. et Rabeler归入孩儿参属的观点,并建议将矮小孩儿参[P. maximowicziana (Franch. et Sav.) Pax]、须弥孩儿参[P. himalaica (Franch.) Pax]和异花孩儿参[P. heterantha(Maxim.) Pax]分别独立成种。从分布区域看,孩儿参属呈北温带间断分布,由北美洲、地中海地区和东亚3个相互隔离的地理区域组成,并且,东亚为其多样化分布中心。
