    全球树门户,由国际植物园保护组织主办,提供有关全球约58,000个树种的信息。GlobalTree门户中包括保护行动追踪器,一个动态和协作的数据库,用于识别和监测全球树种的保护行动。
    保护行动追踪器整理了物种级别的保护行动信息,包括物种恢复/行动计划,异地收藏,传播协议,现场管理,物种保护政策,和教育/宣传活动。
    到目前为止,保护行动追踪器包含4126个树种的保护行动信息,包括2161种濒危物种,其中659人被归类为弱势群体,783濒临灭绝,719是极度濒危的。它涵盖了每个国家至少一种树种的保护行动信息;然而,89%的弱势群体需要更多信息,87%的濒危和77%的濒危树种。
    监测物种保护行动可以通过分享知识来支持保护实践的优先次序和扩大规模,加强合作,能够识别保护差距,并提供信息供决策者使用。跟踪物种一级的保护行动是,因此,对指导未来的保护工作至关重要。增加保护行动追踪器中的数据量将提高该工具指导未来保护工作的能力,避免树种灭绝。
    UNASSIGNED: The GlobalTree Portal, hosted by Botanic Gardens Conservation International, provides access to information on the approximately 58,000 tree species worldwide. Included in the GlobalTree Portal is the Conservation Action Tracker, a dynamic and collaborative database to identify and monitor conservation actions for tree species globally.
    UNASSIGNED: The Conservation Action Tracker collates conservation action information at the species level, including species recovery/action plans, ex situ collections, propagation protocols, in situ management, species protection policy, and education/awareness campaigns.
    UNASSIGNED: To date, the Conservation Action Tracker contains conservation action information for 4126 tree species, including 2161 threatened species, of which 659 are classified as Vulnerable, 783 as Endangered, and 719 as Critically Endangered. It covers conservation action information for at least one tree species in every country; however, more information is needed for 89% of Vulnerable, 87% of Endangered, and 77% of Critically Endangered tree species.
    UNASSIGNED: Monitoring species conservation actions can support the prioritization and scaling up of conservation practices by sharing knowledge, increasing collaboration, enabling the identification of conservation gaps, and making the information available to be used by decision-makers. Tracking conservation actions at the species level is, therefore, essential to guide future conservation efforts. Increasing the amount of data in the Conservation Action Tracker will improve the tool\'s ability to guide future conservation efforts and avoid the extinction of tree species.

    肠炎沙门氏菌是人类食源性沙门氏菌感染和暴发的主要原因。有效监测和及时发现疫情对于公共卫生控制至关重要。具有多级分辨率的多级基因组分型(MGT)先前已被证明是用于此目的的有希望的工具。在这项研究中,我们为肠炎S.开发了9个水平的MGT,并详细描述了肠炎S.的基因组流行病学特征.我们检查了来自86个国家101年的分离株的26670个公开可用的肠炎沙门氏菌基因组序列,以揭示其时空分布。使用较低分辨率的MGT级别,确定了全球流行和区域限制的序列类型(STs);发现了在美国人类病例中常见的鸟类相关MGT4-STs;从2014年至2018年,在英国观察到MGT5-STs的时间趋势,揭示了长寿的地方性STs和新STs的快速扩展。使用MGT3到MGT6,我们在各种MGT水平上鉴定了多药耐药(MDR)相关的STs,这提高了MDR克隆的检测和全局跟踪的精度。我们还发现,全球大多数肠炎沙门氏菌种群属于两个主要谱系,导致大规模爆发的倾向明显不同。已建立了在线开放的MGT数据库,以对肠炎S.进行统一的国际监测。我们证明了MGT为肠炎沙门氏菌监测和暴发检测提供了灵活且高分辨率的基因组分型工具。
    Salmonella enterica serovar Enteritidis is a major cause of foodborne Salmonella infections and outbreaks in humans. Effective surveillance and timely outbreak detection are essential for public health control. Multilevel genome typing (MGT) with multiple levels of resolution has been previously demonstrated as a promising tool for this purpose. In this study, we developed MGT with nine levels for S. Enteritidis and characterised the genomic epidemiology of S. Enteritidis in detail. We examined 26 670 publicly available S. Enteritidis genome sequences from isolates spanning 101 years from 86 countries to reveal their spatial and temporal distributions. Using the lower resolution MGT levels, globally prevalent and regionally restricted sequence types (STs) were identified; avian associated MGT4-STs were found that were common in human cases in the USA; temporal trends were observed in the UK with MGT5-STs from 2014 to 2018 revealing both long lived endemic STs and the rapid expansion of new STs. Using MGT3 to MGT6, we identified multidrug resistance (MDR) associated STs at various MGT levels, which improves precision of detection and global tracking of MDR clones. We also found that the majority of the global S. Enteritidis population fell within two predominant lineages, which had significantly different propensity of causing large scale outbreaks. An online open MGT database has been established for unified international surveillance of S. Enteritidis. We demonstrated that MGT provides a flexible and high-resolution genome typing tool for S. Enteritidis surveillance and outbreak detection.

    这项研究有三个空间尺度:全球(0.5°),宏观区域,和国家规模。干旱事件数据库为每个宏观区域和国家都有特定的条目。
    我们建立了一个1951年至2016年的气象干旱事件数据库,现在由欧盟委员会联合研究中心的全球干旱观测站主办。根据对不同累积尺度(3至72个月)的标准化降水-蒸散指数(SPEI)和标准化降水指数(SPI)的单独分析,在宏观区域和国家尺度上检测到事件,使用全球降水气候学中心(GPCC)和气候研究单位(CRU)时间序列数据集作为输入。该数据库包括大约4800个基于SPEI-3的事件和4500个基于SPI-3的事件。每个事件都由其开始和结束日期来描述,持续时间,强度,严重程度,峰值,干旱的平均和最大面积,和一个特殊的分数来分类52特大干旱。
    我们得出了干旱频率和严重程度的趋势,分别对于SPI和SPEI在12个月的积累规模,这通常与水文干旱有关。结果表明,在过去的几十年中,有几个干旱热点地区:亚马逊,南美洲南部,地中海地区,非洲大部分地区,中国东北和,在较小程度上,中亚和澳大利亚南部。在北美,中欧,中亚,澳大利亚,最近的气温上升超过了降水的增加,导致更频繁和严重的干旱。
    UNASSIGNED: This study has three spatial scales: global (0.5°), macro-regional, and country scale. The database of drought events has specific entries for each macro-region and country.
    UNASSIGNED: We constructed a database of meteorological drought events from 1951 to 2016, now hosted by the Global Drought Observatory of the European Commission\'s Joint Research Centre. Events were detected at macro-regional and country scale based on the separate analysis of the Standardized Precipitation-Evapotranspiration Index (SPEI) and the Standardized Precipitation Index (SPI) at different accumulation scales (from 3 to 72 months), using as input the Global Precipitation Climatology Centre (GPCC) and Climatic Research Unit (CRU) Time Series datasets. The database includes approximately 4800 events based on SPEI-3 and 4500 based on SPI-3. Each event is described by its start and end date, duration, intensity, severity, peak, average and maximum area in drought, and a special score to classify 52 mega-droughts.
    UNASSIGNED: We derived trends in drought frequency and severity, separately for SPI and SPEI at a 12-month accumulation scale, which is usually related to hydrological droughts. Results show several drought hotspots in the last decades: Amazonia, southern South America, the Mediterranean region, most of Africa, north-eastern China and, to a lesser extent, central Asia and southern Australia. Over North America, central Europe, central Asia, and Australia, the recent progressive temperature increase outbalanced the increase in precipitation causing more frequent and severe droughts.

    本研究的目的是使用国际统计数据阐明地中海饮食评分(MDS)与国家IHD发病率之间的全球关系。
    按国家划分的IHD发病率来自全球疾病负担(GBD)数据库。各国平均粮食供应(人均克/天)和能源(人均千卡/天),不包括生产和家庭之间的损失,是从FAOSTAT数据库获得的。根据表征地中海饮食的9种食物的总分评估MDS。使用控制社会经济和生活方式变量的一般线性模型,在人口为100万或以上的国家中检查了MDS与IHD发病率之间的关联。
    来自全球国际数据库的人口数据。参与者一百三十两个人口超过一百万的国家。
    MDS与肥胖率呈负相关,老化率,受教育年限和IHD发病率;然而,没有发现与国内生产总值有关联,预期寿命,吸烟率,能源供应或卫生支出。在由MDS控制的社会经济和生活方式变量的IHD发病率的一般线性模型中,MDS的β为-26·4(se8·6;P<0·01)。
    这项全球国际比较研究的结果证实,地中海饮食与IHD的发病率呈负相关。
    The aim of the present study was to clarify the global relationship between Mediterranean diet score (MDS) and the incidence of IHD by country using international statistics.
    The incidence of IHD by country was derived from the Global Burden of Disease (GBD) database. Average supplies of food (g/d per capita) and energy (kcal/d per capita) by country, excluding loss between production and household, were obtained from the FAOSTAT database. MDS was evaluated based on the total score of nine food items that characterize the Mediterranean diet. The association between MDS and the incidence of IHD was examined in countries with a population of 1 million or greater using a general linear model controlled for socio-economic and lifestyle variables.
    Population data from global international databases.ParticipantsOne hundred and thirty-two countries with a population of over 1 million.
    MDS was inversely correlated with obesity rate, ageing rate, years of education and IHD incidence; however, no associations were found with gross domestic product, life expectancy, smoking rate, energy supply or health expenditure. In the general linear model of IHD incidence by MDS controlled for socio-economic and lifestyle variables, the β of the MDS was -26·4 (se 8·6; P<0·01).
    The results of this global international comparative study confirmed that the Mediterranean diet is inversely associated with the incidence of IHD.
