Data from: sFDvent: a global trait database for deep-sea hydrothermal-vent fauna

Traits are increasingly being used to quantify global biodiversity
patterns, with trait databases growing in size and number, across diverse
taxa. Despite growing interest in a trait-based approach to the
biodiversity of the deep sea, where the impacts of human activities
(including seabed mining) accelerate, there is no single repository for
species traits for deep-sea chemosynthesis-based ecosystems, including
hydrothermal vents. Using an international, collaborative approach, we
have compiled the first global-scale trait database for deep-sea
hydrothermal-vent fauna - sFDvent (sDiv-funded trait database for the
Functional Diversity of vents). We formed a funded working group to select
traits appropriate to: i) capture the performance of vent species and
their influence on ecosystem processes, and ii) compare trait-based
diversity in different ecosystems. Forty contributors, representing
expertise across most known hydrothermal-vent systems and taxa, scored
species traits using online collaborative tools and shared workspaces.
Here, we typify the sFDvent database, describe our approach, and evaluate
its scope. Finally, we compare the sFDvent database to similar databases
from shallow-marine and terrestrial ecosystems to highlight how the
sFDvent database can inform cross-ecosystem comparisons. We also make the
sFDvent database publicly available online by assigning a persistent,
unique doi. 646 vent species names, associated location information (33
regions), and scores for 13 traits (in categories: community structure,
generalist/specialist, geographic distribution, habitat use, life history,
mobility, species associations, symbiont, and trophic structure).
Contributor IDs, certainty scores, and references are also provided.
Global coverage (grain size: ocean basin), spanning eight ocean basins,
including vents on 12 mid-ocean ridges and 6 back-arc spreading centres.
sFDvent includes information on deep-sea vent species, and associated
taxonomic updates, since they were first discovered in 1977. Time is not
recorded. The database will be updated every five years. Deep-sea
hydrothermal-vent fauna with species-level identification present or in

性状（Trait）正日益被用于量化全球生物多样性格局，跨多样类群的性状数据库在规模与数量上均呈增长态势。尽管基于性状的深海生物多样性研究方法愈发受到关注——且人类活动（包括海底采矿）的影响正加速加剧，但目前尚无针对深海化能合成生态系统（包括热液喷口（hydrothermal vents））的物种种状单一整合数据库。本研究采用国际协作模式，编制了首个全球尺度的深海热液喷口动物群性状数据库——sFDvent（由sDiv资助的喷口功能多样性性状数据库）。我们组建了受资助的工作组，用于遴选适配以下两类目标的性状：其一，能够反映喷口物种种状表现及其对生态系统过程的影响；其二，可用于比较不同生态系统中基于性状的多样性。共有40名来自全球多数已知热液喷口系统与类群研究领域的贡献者，通过在线协作工具与共享工作空间完成了物种种状的评分工作。本文首先阐明sFDvent数据库的特征，详述研究方法，并评估其覆盖范围。最后，我们将sFDvent数据库与浅海及陆地生态系统的同类数据库进行对比，以凸显该数据库如何为跨生态系统比较研究提供支撑。此外，我们为该数据库分配了唯一且永久的数字对象标识符（Digital Object Identifier，DOI），使其可在线公开获取。该数据库包含646个喷口物种名称、相关的位置信息（覆盖33个区域）以及13类性状的评分，性状类别涵盖：群落结构、泛化/特化类型、地理分布、生境利用、生活史、移动性、物种互作、共生体以及营养结构。同时还提供了贡献者ID、评分置信度与参考文献信息。数据库的全球覆盖范围（空间粒度：洋盆尺度）涵盖8个大洋盆地，包括12条洋中脊与6个弧后扩张中心上的热液喷口。sFDvent收录了自1977年热液喷口物种首次被发现以来的深海喷口物种信息及相关分类学更新内容，未记录时间维度信息。该数据库将每五年更新一次。收录的类群为已完成或正在进行物种水平鉴定的深海热液喷口动物群。数据格式包含逗号分隔值（.csv）与微软Excel（.xlsx）格式。
