Abstract：
Mesopelagic organisms play a crucial role in marine food webs, channelling energy across the predator-prey network and connecting depth strata through their diel vertical migrations. The information available to assess mesopelagic feeding interactions and energy transfer has increased substantially in recent years, owing to the growing interest and research activity in the mesopelagic realm. However, such data have not been systematically collated and are difficult to access, hampering estimation of the contribution of mesopelagic organisms to marine ecosystems. Here we present MesopTroph, a georeferenced database of diet, trophic markers, and energy content of mesopelagic and other marine taxa compiled from 203 published and non-published sources. MesopTroph currently includes data on stomach contents, carbon and nitrogen stable isotopes, major and trace elements, energy density, fatty acids, trophic positions, and diet proportion estimates for 498 species/genera. MesopTroph will be expanded with new data emerging from ongoing studies. MesopTroph provides a unique tool to investigate trophic interactions and energy flow mediated by mesopelagic organisms, and to evaluate the ecosystem services of this community.
摘要：
中生生物在海洋食物网中发挥着至关重要的作用，通过捕食者-猎物网络引导能量，并通过diel垂直迁移连接深度地层。近年来，用于评估中胚层摄食相互作用和能量转移的信息已大大增加，由于对中观领域的兴趣和研究活动日益增长。然而,这些数据没有经过系统的整理，难以获取，阻碍了中生生物对海洋生态系统贡献的估计。这里我们介绍MesopTroph，一个地理参考的饮食数据库，营养标记，以及从203个已发布和未发布的来源汇编的中生和其他海洋分类单元的能量含量。MesopTroph目前包括胃内容物的数据，碳和氮稳定同位素，主要和微量元素，能量密度，脂肪酸，营养位置，和498种/属的饮食比例估计。MesopTroph将通过正在进行的研究中出现的新数据进行扩展。MesopTroph提供了一个独特的工具来研究中生生物介导的营养相互作用和能量流，并评估该社区的生态系统服务。
