A food web including parasites for kelp forests of the Santa Barbara Channel, California

We built a high-resolution topological food web for the kelp forests of the Santa Barbara Channel, California, USA that includes parasites and significantly improves resolution compared to previous webs. The 1,098 nodes and 21,956 links in the web describe an economically, socially, and ecologically vital system. Nodes are broken into life-stages. There are 549 free-living life-stages (comprising 492 species from 21 Phyla) and 549 parasitic life-stages (comprising 450 species from 10 Phyla). Links represent three kinds of trophic interactions. There are 9,352 predator-prey links, 2,733 parasite-host links and 9,871 predator-parasite links. This food web is unique in that all decisions for including nodes and links are documented, and extensive metadata in the node list allows users to filter the node list to suit their research questions. The kelp-forest food web is more species rich than any other published food web with parasites, and has a larger proportion of parasitic species than ...

我们针对美国加利福尼亚州圣巴巴拉海峡的海藻林构建了一套包含寄生生物的高分辨率拓扑食物网，相较于此前已有的食物网，该网络的分辨率得到了显著提升。该食物网共包含1098个节点与21956条连接边，刻画了一个在经济、社会与生态层面均具有重要价值的生态系统。节点按生活史阶段进行划分，其中包含549个自由生活史阶段（涵盖21个门的492个物种）与549个寄生生活史阶段（涵盖10个门的450个物种）。连接边代表三类营养交互作用，分别为9352条捕食者-猎物连接边、2733条寄生虫-宿主连接边以及9871条捕食者-寄生虫连接边。该食物网的独特之处在于，所有节点与连接边的纳入决策均留有完整文档记录，且节点列表附带丰富的元数据，使用者可根据自身研究需求对节点列表进行筛选。相较于其他已发表的含寄生生物食物网，该海藻林食物网的物种丰富度更高，且寄生物种占比也更高……
