Mining metadata from unidentified ITS sequences in GenBank: A case study in ()-3

represents climate according to the Köppen-Geiger climate classification (modified from [28]); main climate A = equatorial, B = arid, C = warm temperate, D = snow, E = polar; precipitation W = desert, S = steppe, f = fully humid, s = summer dry w = winter dry, m = monsoonal; temperature h = hot arid, k = cold arid, a = hot summer, b = warm summer, c = cool summer, d = extremely continental, F = polar frost, T = polar tundra. Black symbols represent studies with unidentified sequences, white symbols represent studies with fully identified sequences, and grey symbols represent studies with both unidentified and fully identified sequences. Circles represent studies for which the coordinates were given in the paper in which they were published, diamonds represent studies where the location had to be inferred from the locality given in the paper, and squares represent studies where the location was not available beyond the country/state level. The numbers correspond to the number given to each study in the Additional file .<b>Copyright information:</b>Taken from "Mining metadata from unidentified ITS sequences in GenBank: A case study in ()"http://www.biomedcentral.com/1471-2148/8/50BMC Evolutionary Biology 2008;8():50-50.Published online 18 Feb 2008PMCID:PMC2275786.

本数据集采用柯本-盖格气候分类法（Köppen-Geiger climate classification）表征气候特征，修改自文献[28]；其中主要气候带划分规则为：A为赤道气候带，B为干旱气候带，C为暖温带气候带，D为降雪气候带，E为极地气候带；降水亚型分类规则为：W代表荒漠型，S代表草原型，f代表全湿润型，s代表夏季干燥型，w代表冬季干燥型，m代表季风型；温度亚型分类规则为：h代表热干旱型，k代表冷干旱型，a代表暖夏季型，b代表温夏季型，c代表凉夏季型，d代表极端大陆性型，F代表极地冰原型，T代表极地苔原型。黑色符号代表序列未鉴定的研究，白色符号代表序列完全鉴定的研究，灰色符号代表同时包含未鉴定与完全鉴定序列的研究。圆圈代表论文原文中已明确给出采样坐标的研究，菱形代表需依据论文记载的采集地推断具体位置的研究，方形代表仅能获取国家/州级层面位置信息的研究。图中数字对应附加文件中为各研究所赋予的编号。<b>版权信息：</b>本内容取自《从GenBank（基因银行）中未鉴定的内转录间隔区（Internal Transcribed Spacer, ITS）序列挖掘元数据：一则（）案例研究》，原文链接为http://www.biomedcentral.com/1471-2148/8/50，刊载于《BMC进化生物学》2008年；8卷：50-50页，于2008年2月18日在线发表，PMCID：PMC2275786。
