Contemporary phenotypic change in plant quantitative traits

This is a new version of the Gorné &amp; Díaz 2017 database (doi:10.5281/zenodo.580095). We cheked the categorization of each case, fixed of some mistakes. Also, we disambiguated the trait type moderator and add a new (mean based) measure of change. This database included studies that provide data of changes in quantitative traits of angiosperms within a known temporal framework (&lt;300 years). The search was performed by Scopus (www.scopus.com), up to 22 December 2015 (search strings in Gorné and Díaz 2017). The database includes studies that measured intraspecific change in a quantitative trait and which report the elapsed time when the phenotypic change occurred. The studies recorded a single population before and after a change in the environment or compared two (or more) populations by measuring a quantitative trait across two situations, where one of them was a new condition of known age. Both, by measuring change directly in the field or by performing common condition experiments (e.g. common garden experiments or reciprocal transplants). Studies reporting results from artificial selection or interspecific hybridization were excluded. The environmental changes included expansions of distributional range, soil or air pollution, exposure to herbicides, changes in salinity, pH, climate, disturbance or irrigation regime, and addition or loss of species in the local community. All data available in each study were recorded, including several observations of the same species. These procedures resulted in a database containing 1716 observations from 128 studies, with changes in populations of 152 species from 34 families, in elapsed times of &lt; 260 years, and covering a wide range of traits, lifespan, growth forms and environmental situations. All data points were categorized according to biological properties of the study system (lifespan, growth form, trait type) and methodological ones. The amount and rate of phenotypic change is expresed as the standardized mean difference Hedges <em>g</em> (Hedges 1981, 1982), a rate of change which is the Hedges <em>g</em> over the elapsed time in years, and the log-transformation of both of them. The standardized mean difference is equal to the <em>haldane</em> numerator, which is a standard rate of evolution (Haldane 1949; Gingerich 1993). In addition, we upgraded the Díaz and Gorné (2017) database, computing the response ratio effect size (<em>logRR</em>) (Hedges et al. 1999) whenever possible. The response ratio is a mean-scaled metric equal to the <em>darwins</em> numerator (Haldane 1949). So that we compute a rate of change similar to <em>darwins</em> (time expressed as years instead of million years). contact email address: [e-mail]本数据集为Gorné与Díaz于2017年发布的数据库（DOI:10.5281/zenodo.580095）的更新版本。我们对每条记录的分类进行了核查，修正了部分错误。此外，我们厘清了性状类型调节变量的定义歧义，并新增了一种基于均值的变化量测度方法。本数据库收录了在已知时间框架（<300年）内被子植物（angiosperms）数量性状发生变化的相关研究。文献检索依托Scopus数据库（www.scopus.com）完成，检索截止至2015年12月22日，检索字符串详见Gorné与Díaz 2017年的研究。入选研究需量化测定某一数量性状的种内变化，并报告表型变化发生所经历的时长。此类研究要么直接在野外环境中记录同一种群在环境改变前后的性状差异，要么通过两种（或多种）情境下的数量性状测定对比不同种群，其中至少一种情境为已知形成时间的新生环境。上述测定既可通过野外直接监测完成，也可借助同质园实验（common garden experiments）或互惠移植实验（reciprocal transplants）等受控条件实验开展。本数据集排除了涉及人工选择或种间杂交的研究结果。纳入研究涵盖的环境改变包括：分布范围扩张、土壤或空气污染、除草剂暴露、盐度变化、pH变化、气候改变、干扰或灌溉制度变化，以及本地群落的物种迁入或丧失。本研究收录了每项入选研究中的全部可用数据，包括同一物种的多次观测结果。经上述流程整理后，本数据库共包含来自128项研究的1716条观测记录，涉及34科152个物种种群的性状变化，观测时长均小于260年，覆盖了广泛的性状类型、寿命、生长型及环境情境。所有数据点均根据研究系统的生物学属性（寿命、生长型、性状类型）及方法学属性进行了分类。表型变化的幅度与速率以标准化均数差Hedges *g*（Hedges 1981, 1982）表示，变化速率则为Hedges *g*除以以年为单位的观测时长，同时对这两个指标进行了对数转换。该标准化均数差等价于霍尔丹进化速率（haldane）的分子项，是一种标准的进化速率指标（Haldane 1949; Gingerich 1993）。此外，我们对Díaz与Gorné（2017）的原始数据库进行了升级，在可行的情况下计算了响应比效应量（logRR）（Hedges et al. 1999）。响应比是一种经均值标准化的度量指标，等价于达尔文进化速率（darwins）的分子项，据此我们计算出了以年而非百万年为时间单位的类达尔文变化速率。联系邮箱：[e-mail]
