Data and code from: Accounting for species interactions is necessary for predicting how arctic arthropod communities respond to climate change

The data were collected as part of the GEM program in Zackenberg, a High Arctic site located in North-East Greenland (74°28’ N; 20°34’ W). Arthropods were sampled weekly during the growing season from 1997 to 2013, using yellow-pitfall traps located in a mesic heath habitat. The material derives from three traps located 5 meters from each other. The 2010 samples were lost in transit from Greenland, so data from this year are missing. The species data was derived mostly from mitogenome mapping (see Ji et al 2020). The species data were complemented with individually DNA-barcoded samples in the case of samples with few individuals, and data on Diptera species from subsamples that had been identified in an independent morphological study (but had not yet been returned and thus could not be sequenced). The species data is accompanied by functional information in the form of the trophic levels (herbivore, omnivore, parasitoid, predator, saprophage or detritivore). As environmental data, there are data on weekly air temperatures (2 m aboveground) and snow depth (downloaded from From GEM’s ClimateBasis program).

本数据集采集自位于格陵兰东北部（北纬74°28′，西经20°34′）的高北极站点扎肯本（Zackenberg）的GEM计划。1997年至2013年的生长季内，研究人员使用放置在中生性石楠灌丛生境中的黄色陷阱诱捕器，每周对节肢动物（Arthropods）开展采样。本次采样使用的三个陷阱诱捕器间距均为5米。2010年的样本在从格陵兰转运途中遗失，因此该年份的数据缺失。物种数据主要通过线粒体基因组（mitogenome）图谱分析获得，详见Ji等人2020年的研究。针对个体数量较少的样本，物种数据通过经DNA条形码（DNA-barcoded）标记的单个样本进行补充；双翅目（Diptera）物种的数据则来自独立形态学研究中已鉴定的子样本，但此类子样本尚未返还，因此无法进行测序。物种数据附带营养级（trophic levels）维度的功能信息，涵盖植食者（herbivore）、杂食者（omnivore）、寄生性天敌（parasitoid）、捕食者（predator）、食腐者（saprophage）以及腐食者（detritivore）。环境数据包含每周的离地2米处气温与雪深数据，此类数据下载自GEM计划的ClimateBasis项目。如需了解数据生成的更多细节，请参阅Abrego等人2021年发表于期刊《Ecography》的论文，原文标题为：Accounting for species interactions is necessary for predicting how arctic arthropod communities respond to climate change。
