目的通过比较物种描述率来预测未描述物种的数量。这些数据被用来讨论的优点，各种尝试估计物种丰富度在oceans.LocationEuropean marine areas.MethodsPredictions有多少物种可能存在于地球上缺乏一个清单，有多少已被描述，除了一些小类群。海洋是一个很好的地方开始一个清单，因为它包括所有，但其中一个门和大多数类的生命在地球上。欧洲海洋物种登记册（ERMS）由分类专家编制，涵盖所有海洋分类群，并说明了同义词。反映分类历史，欧洲的物种是最好的描述在world.ResultsERMS列出29,713种动物，植物和原生生物，但不包括细菌和病毒。估计有6500种描述的物种没有被包括在内。最好的预测数为5613种。当物种首次被描述的年份图显示，除了鸟类，哺乳动物和磷虾外，任何分类群的描述率都没有下降。如果分类努力增加了，无论是由于全球更多的资源还是更高的生产效率，那么每单位努力的描述率可能会下降，未描述物种的数量可能会低于预测。然而，除了减少率的描述在世界大战期间，有没有变化的描述率，可以很容易地归因于这样的factors.ConclusionsThere是约36，000种描述从欧洲海域，我们预测，40，000至48，000可能存在。这包括估计230，000描述的海洋物种的15%。然而，与其他海洋相比，这一地区是众所周知的，其他地方尚未发现的物种比例将更高。
AimIn this paper, we compare species description rates to predict the numbers of undescribed species. These data are used to discuss the merits of various attempts to estimate species richness in the oceans.LocationEuropean marine areas.MethodsPredictions of how many species may exist on Earth have lacked an inventory of how many have been described, except for a few small taxa. The ocean is a good place to start an inventory because it includes all but one of the phyla and most classes of life on Earth. The European Register of Marine Species (ERMS) was compiled by taxonomic experts, covered all marine taxa, and accounted for synonyms. Reflecting taxonomic history, Europe's species are the best described in the world.ResultsERMS listed 29,713 species of animals, plants and protists, but excluded bacteria and viruses. An estimated 6500 described species were not included. The best prediction of the number of species remaining to be described was 5613. Plots of years when species were first described showed no decrease in the rate of description for any taxa except birds, mammals and krill. If taxonomic effort has increased, whether due to more resources globally or greater efficiencies of productivity, then description rates per unit effort may be declining and the number of undescribed species may be lower than predicted. However, apart from reduced rates of description during the World Wars, there were no changes in description rates that could be easily attributed to such factors.ConclusionsThere are about 36,000 species described from European seas, and we predict that 40,000 to 48,000 may exist. This comprises 15% of the estimated 230,000 described marine species. However, this area is well known compared with other seas and the proportion of species yet to be discovered will be higher elsewhere.
