Abstract

The Global Biodiversity Information Facility (GBIF) is the largest databank on primary biodiversity data. We examined the completeness and geographical biases for all insect data on GBIF to determine its representativeness. Our results demonstrate that GBIF is far from providing a reliable representation about the global distribution of insects. Despite the growing number of records during the last years, few spatial units are well‐surveyed. At coarse resolutions, 34% of the world terrestrial cells lack data and barely 0.5% have completeness values above 90%. Insects are crucial in many ecological functions, and their alarming decline makes it more pressing to have a representative sample to improve our predictive capacity. However, the dynamic nature of species distributions and the strength of anthropogenic forces call for immediate conservation decisions that cannot wait for the empirical data on the identity and distribution of insects.

GBIF不能提供昆虫全球分布的代表性图像
全球生物多样性信息基金是最大的初级生物多样性数据数据库。我们检查了GBIF上所有昆虫数据的完整性和地理偏差,以确定其代表性。我们的研究结果表明,GBIF远不能提供昆虫全球分布的可靠代表。尽管在过去几年中记录的数量不断增加,但很少有空间单元得到很好的调查。在粗略的分辨率下,世界上34%的陆地细胞缺乏数据,只有0.5%的细胞的完整性值超过90%。昆虫在许多生态功能中都至关重要,它们惊人的数量下降使我们更迫切需要一个有代表性的样本来提高我们的预测能力。然而,物种分布的动态性质和人为力量的强度要求立即做出保护决定,而不能等待关于昆虫身份和分布的经验数据。
