人类长期以来一直对鱼类迁徙的奥秘着迷,解决这些复杂的行为通常需要大量的数据集。生物地球化学标签,包括微量元素和稳定同位素,是追踪鱼类迁徙的最容易获得的生物标志物。然而,很难获得标准化的生物地球化学标签数据,这限制了我们对进化起源的理解,司机,定时,和移民走廊。这妨碍了保护战略的制定和管理行动的实施。这里,我们介绍MFishBT,一个全球性的,迁徙鱼类生物地球化学标签的开放访问数据库。截至2023年4月,MFishBT包含1305项研究的生物地球化学记录,其中53%使用元素钙比(E/Ca),34%使用同位素比,13%的人同时使用。该数据库涵盖17,413个现场抽样地点(内陆47%与海洋53%)在全球范围内,包括四类490种迁徙鱼类,44个订单/子订单,137个家庭在各种鱼类生物档案中测量了77种微量元素和11种同位素系统,包括耳石,scales,眼睛镜片,和椎骨。E/Ca比率比同位素比率更频繁地检查,以Sr/Ca为首,Mg/Ca,Ba/Ca,和87Sr/86Sr,δ13C,和δ18O,分别。MFishBT编制了27,030、16,222和2,481,714条记录,并在核心中检测到生物地球化学数据,边缘,以及洄游鱼类生物档案的核心到边缘样带,分别。这是迄今为止全球最全面的关于洄游鱼类生物地球化学标签的开放存取数据库,可以满足科学研究的各种需求,养护,和管理。我们鼓励研究人员在将来向该数据库添加更多数据集。此数据库仅用于非商业用途。没有版权限制,在使用这些数据时,请引用这篇论文,或这些数据的子集,用于出版。
Humans have long been fascinated by the mysteries surrounding fish migrations and addressing these complex behaviors often requires large data sets. Biogeochemical tags, including trace elements and stable isotopes, are the most accessible biomarkers for tracking fish migrations. However, access to standardized biogeochemical tag data is rarely available for migratory fish, which limits our understanding of the evolutionary origins, drivers, timing, and corridors of migration. This precludes the development of conservation strategies and the implementation of management actions. Here, we present MFishBT, a global, open-access database of Migratory Fish\'s Biogeochemical Tags. As of April 2023, the MFishBT contains biogeochemical records from 1,305 studies, of which 53% used element-to-calcium (E/Ca) ratios, 34% used isotopic ratios, and 13% used both. The database covers 17,413 field sampling locations (inland 47% vs. marine 53%) around the globe, comprising 490 migratory fish species of four classes, 44 orders/suborders, and 137 families. In total, 77 trace elements and 11 isotope systems were measured across various fish biological archives, including otoliths, scales, eye lenses, and vertebrae. E/Ca ratios were examined more frequently than isotopic ratios, led by Sr/Ca, Mg/Ca, Ba/Ca, and 87 Sr/86 Sr, δ13 C, and δ18 O. The MFishBT compiles 27,030, 16,222, and 2,481,714 records with biogeochemical data detected in the core, edge, and core-to-edge transects for biological archives of migratory fish. This is the most globally comprehensive open-access database on biogeochemical tags in migratory fish to date, and can serve a variety of needs in scientific research, conservation, and management. We encourage researchers to add more data sets to this database in the future. This database is released for noncommercial use only.
