Trophic interaction data and taxonomic information for fish predators and their prey spanning the North East Atlantic and its marginal seas between 1836-2013

Taxonomic information and the diet matrix for fish species-size-classes (rows) and their prey (columns) used to produce feeding guilds via cluster analysis for Thompson et al. (2020) ‘A feeding guild indicator to assess environmental change impacts on marine ecosystem structure and functioning’. Journal of Applied Ecology. The purpose of this study was to propose a food web indicator which has been explicitly called for to inform policy via food web status assessment as part of the European Union’s Marine Strategy Framework Directive and the indicator toolkit supporting The Convention for the Protection of the Marine Environment of the North-East Atlantic (the ‘OSPAR Convention'). We use fish stomach contents data from DAPSTOM (https://www.cefas.co.uk/data-and-publications/fish-stomach-records/) and ICES Year of the Stomach (https://ices.dk/data/data-portals/Pages/Fish-stomach.aspx). DAPSTOM is an ongoing initiative digitizing fish stomach records. The database contains information collected between 1836-2013 on 187 predator species (most occurring in northern European groundfish surveys). ICES Year of The Stomach Dataset contains records from 35 fish species between 1980-1991 sampled in the North Sea. Both datasets have information on predator-prey interactions for given sea areas and years. The new trophic interaction dataset presents binary information of interactions detected from across the North East Atlantic and its marginal seas, from 415,294 fish stomachs.本数据集收录了Thompson等人2020年发表于《应用生态学杂志》（Journal of Applied Ecology）的论文《用于评估环境变化对海洋生态系统结构与功能影响的摄食功能群指示物》（A feeding guild indicator to assess environmental change impacts on marine ecosystem structure and functioning）中，用于通过聚类分析构建摄食功能群的鱼类物种-体型类群（行）与猎物（列）的分类学信息及食性矩阵。本研究旨在提出一种食物网指示物——该需求已被明确提出，用于作为欧盟《海洋战略框架指令》以及支持《东北大西洋海洋环境保护公约》（OSPAR Convention）的指示物工具包的组成部分，通过食物网状态评估为政策制定提供科学支撑。本数据集采用了两类公开的鱼类胃含物数据：其一为DAPSTOM项目（https://www.cefas.co.uk/data-and-publications/fish-stomach-records/）的数据，该项目为持续开展的鱼类胃记录数字化计划，其数据库收录了1836年至2013年间采集的187种捕食性鱼类的相关信息，多数记录源自北欧底栖鱼类调查；其二为ICES《胃含物之年》（ICES Year of the Stomach，https://ices.dk/data/data-portals/Pages/Fish-stomach.aspx）数据集，该数据集包含了1980年至1991年间在北海采样的35种鱼类的观测记录。两类数据集均涵盖特定海域与对应年份下的捕食者-猎物相互作用信息。本新型营养相互作用数据集整合了东北大西洋及其边缘海范围内415294份鱼类胃样本所检出的相互作用二元数据。
