生物扰动是沉积物通过颗粒改造和洞穴通风而发生的生物改造，是海洋系统中许多重要地球化学过程的关键媒介。生物扰动的原位定量可以通过多种方式实现，需要专业知识，技术和资源并不总是可用的，并且在某些情况下不可行。在没有专门的研究方案的地方，一个实际的替代办法是采用基于特征的方法来估计社区生物扰动潜力。这一指数可根据物种、丰度和生物量数据清单（许多系统通常可获得）以及与沉积物混合有关的生物特征功能分类（较少获得）计算。然而，目前还没有商定的海底物种改造模式和流动性标准分类。根据文献和专家意见的信息，我们提供了一个功能分类1033底栖无脊椎动物物种从西北欧大陆架，作为一种工具，使该地区的BPC标准化计算。今后使用这一分类表将提高对受生物扰动影响的生态系统过程和功能进行大规模评估的可比性和实用性（例如，支持立法）。关键的优势，假设和限制BPc作为一个指标进行了严格审查，其计算和应用提供指导方针。
Bioturbation, the biogenic modification of sediments through particle reworking and burrow ventilation, is a key mediator of many important geochemical processes in marine systems. In situ quantification of bioturbation can be achieved in a myriad of ways, requiring expert knowledge, technology, and resources not always available, and not feasible in some settings. Where dedicated research programmes do not exist, a practical alternative is the adoption of a trait-based approach to estimate community bioturbation potential (BPc). This index can be calculated from inventories of species, abundance and biomass data (routinely available for many systems), and a functional classification of organism traits associated with sediment mixing (less available). Presently, however, there is no agreed standard categorization for the reworking mode and mobility of benthic species. Based on information from the literature and expert opinion, we provide a functional classification for 1033 benthic invertebrate species from the northwest European continental shelf, as a tool to enable the standardized calculation of BPc in the region. Future uses of this classification table will increase the comparability and utility of large-scale assessments of ecosystem processes and functioning influenced by bioturbation (e.g., to support legislation). The key strengths, assumptions, and limitations of BPc as a metric are critically reviewed, offering guidelines for its calculation and application.
