目的海洋中栖息着各种各样的生物，人们对它们的分布和生态偏好往往知之甚少。物种分布模型（SDM）可以提高我们的认识，为海洋生态系统的管理和保护提供信息。虽然海洋环境数据可以从各种来源获得，但目前还没有为SDM应用设计的用户友好的高分辨率全球数据集。本研究旨在通过组装一个全面、统一、高分辨率和易于使用的全球环境光栅包来填补这一空白。全球定位，海运。方法收集了与物种分布相关的海洋环境的各个方面的全球覆盖数据，如卫星数据和实地测量数据。光栅以5角分（约9.2公里）的分辨率组装，并应用了统一的陆地掩模。利用入侵海藻Codium fragile ssp的最大熵SDM评价数据集的实用性。脆弱的。我们提出了一个由23个地球物理、生物和气候栅格组成的全球数据集Bio-ORACLE（海洋栅格用于气候和环境分析）。这个海洋物种分布模型的用户友好数据包可在http://www.bio-oracle.ugent.be下载。该分布模型具有较高的预测能力。fragile清楚地说明了浅水海洋生物SDM数据包的潜力。这一全球环境数据包的可用性有可能刺激海洋SDM。一种臭名昭著的入侵海藻的仅存在模型的高预测成功率表明，Bio-ORACLE中包含的信息可以提供有关海洋分布的信息，并允许建立高度精确的物种分布模型。
Aim The oceans harbour a great diversity of organisms whose distribution and ecological preferences are often poorly understood. Species distribution modelling (SDM) could improve our knowledge and inform marine ecosystem management and conservation. Although marine environmental data are available from various sources, there are currently no user-friendly, high-resolution global datasets designed for SDM applications. This study aims to fill this gap by assembling a comprehensive, uniform, high-resolution and readily usable package of global environmental rasters.Location Global, marine.Methods We compiled global coverage data, e. g. satellite-based and in situ measured data, representing various aspects of the marine environment relevant for species distributions. Rasters were assembled at a resolution of 5 arcmin (c. 9.2 km) and a uniform landmask was applied. The utility of the dataset was evaluated by maximum entropy SDM of the invasive seaweed Codium fragile ssp. fragile.Results We present Bio-ORACLE (ocean rasters for analysis of climate and environment), a global dataset consisting of 23 geophysical, biotic and climate rasters. This user-friendly data package for marine species distribution modelling is available for download at http://www.bio-oracle.ugent.be. The high predictive power of the distribution model of C. fragile ssp. fragile clearly illustrates the potential of the data package for SDM of shallow-water marine organisms.Main conclusions The availability of this global environmental data package has the potential to stimulate marine SDM. The high predictive success of the presence-only model of a notorious invasive seaweed shows that the information contained in Bio-ORACLE can be informative about marine distributions and permits building highly accurate species distribution models.
