Figure S2

Figure S2: Average completeness of the GBIF mediated data per year does not evolve along time. The blue line represents the average proportion of columns filled in the DarwinCore format. The blue area represents the standard deviation of this value. The average completeness of the data does not change much over the years and is never above 25 %.补充图S2：全球生物多样性信息设施（GBIF，Global Biodiversity Information Facility）介导数据的年均完整度未随时间发生显著变化。蓝色线条代表达尔文核心（DarwinCore）格式下各字段的平均填充比例，蓝色阴影区域代表该数值的标准差。该数据的平均完整度在多年间并无明显波动，且始终未超过25%。
