Evan Parker at Yale University, USA, and colleagues from the USA assessed coverage and biases in 33,016 potential distribution reports for 12,009 species. They showed taxonomic and geographic biases, with higher coverage of birds, gymnosperms and European and US species, and lower coverage of insects, Amphibia and species in temperate South America, Australia, the tropics and polar regions. Within species, studies were biased towards the colder parts of species distributions, with only 8% of the species assessed at both ends of their ranges. The work highlights the need for accounting of current biases and management of future data collection to address gaps.

美国耶鲁大学的 Evan Parker 和美国同事评估了 12,009 个物种的 33,016 份潜在分布报告的覆盖范围和偏差。它们表现出分类学和地理偏差，鸟类、裸子植物和欧洲和美国物种的覆盖率较高，而昆虫、两栖类和南美洲温带、澳大利亚、热带和极地地区的物种覆盖率较低。在物种内部，研究偏向于物种分布的较冷部分，只有 8% 的物种在其分布范围的两端进行了评估。这项工作强调需要考虑当前的偏见并管理未来的数据收集以弥补差距。
