该数据集提供了三个北美太平洋沿岸河口的食物网和一个由所有三个河口的物种/阶段组成的“元网”。这些网络有四个值得注意的属性：（1）寄生虫（传染性病原体），（2）体型信息，（3）生物量信息，（4）许多具有复杂生命周期的动物的个体发育阶段。河口是卡平特里亚盐沼，加州（CSM）;埃斯埃斯特罗德蓬塔班达，下加利福尼亚（EPB）;和巴伊亚法尔萨在巴伊亚圣昆廷，下加利福尼亚（BSQ）。大多数物种组合和寄生的数据收集通过一致的采样，获得身体大小和生物量的信息大于1毫米的植物和动物，并为许多传染病病原体（主要是后生动物寄生虫，但也有一些微生物）。我们用来自其他公开来源的信息和对未代表的群体（例如，浮游生物）。我们估计自由生活的消费者资源链接主要是通过扩展以前发布的版本的CSM网络（目前的CSM网络取代），并确定最寄生虫的消费者资源链接从直接观察。我们认识到21个可能的链接类型，包括四个一般的相互作用：捕食者消费猎物，寄生虫消费主机，捕食者消费寄生虫，寄生虫消费寄生虫。虽然一般解决了物种水平，我们报告的阶段特定的节点，许多动物具有复杂的生命周期。我们为每个节点包括额外的生物信息，如分类，生活方式（自由生活，传染性，寄生虫，互利主义者），流动性和居住地。元网络包括500个节点，314个物种，和11270个链接，预计将出现适当的物种的共同出现。其中，9247链接存在于一个或多个河口网。其余2023个链接不存在于河口，但在这里包括，因为它们可能发生在其他地方或时间。初步分析已经审查并正在审查消费者战略、体型、丰度、生物量、营养级、生命阶段和食物网结构和动态之间的相互关系。进一步使用这些数据可能会更广泛地探索传染过程和寄生虫如何影响社区和生态系统。此外，我们目前的数据和元数据在一个标准化的格式，试图提供一个系统中立的模板，为未来的食物网组装和出版。
This data set presents food webs for three North American Pacific coast estuaries and a "Metaweb" composed of the species/stages compiled from all three estuaries. The webs have four noteworthy attributes: (1) parasites (infectious agents), (2) body-size information, (3) biomass information, and (4) ontogenetic stages of many animals with complex life cycles. The estuaries are Carpinteria Salt Marsh, California (CSM); Estero de Punta Banda, Baja California (EPB); and Bahia Falsa in Bahia San Quintin, Baja California (BSQ). Most data on species assemblages and parasitism were gathered via consistent sampling that acquired body size and biomass information for plants and animals larger than 1 mm, and for many infectious agents (mostly metazoan parasites, but also some microbes). We augmented this with information from additional published sources and by sampling unrepresented groups (e.g., plankton). We estimated free-living consumer-resource links primarily by extending a previously published version of the CSM web (which the current CSM web supplants) and determined most parasite consumer-resource links from direct observation. We recognize 21 possible link types including four general interactions: predators consuming prey, parasites consuming hosts, predators consuming parasites, and parasites consuming parasites. While generally resolved to the species level, we report stage-specific nodes for many animals with complex life cycles. We include additional biological information for each node, such as taxonomy, lifestyle (free-living, infectious, commensal, mutualist), mobility, and residency. The Metaweb includes 500 nodes, 314 species, and 11 270 links projected to be present given appropriate species' co-occurrences. Of these, 9247 links were present in one or more of the estuarine webs. The remaining 2023 links were not present in the estuaries but are included here because they may occur in other places or times. Initial analyses have examined and are examining the interrelationships among consumer strategy, body size, abundance, biomass, trophic level, life stages, and food-web structure and dynamics. Further use of these data may enable a more general exploration how infectious processes and parasites impact communities and ecosystems. Additionally, we present the data and metadata in a standardized format, attempting to provide a system-neutral template for future food-web assembly and publication.
