title: A parasite-inclusive food web for the California rocky intertidal zone

description: We present a highly resolved, species rich food web, including parasitic
 interactions, for the California rocky intertidal zone. The food web is
 comprised of 1809 nodes, representing 1845 taxa, and 13,222 links
 representing trophic interactions between nodes. While only 677 links
 represent parasitic interactions, we that we have assembled most speciose
 parasite-inclusive food web ever published. The inclusion of all nodes and
 links are justified using multiple lines of evidence which are built in to
 the dataset. In addition, metadata, including trophic strategy, taxonomic
 information, habitat, and other ecological attributes allow the data user
 to filter the food web to their specifications. The food web is a powerful
 and flexible tool for researchers with questions about large network
 properties, ecological dynamics of rocky shores, and the role of parasites
 in ecosystems. Our food web can be used to predict how complex ecosystems
 like the California rocky intertidal will respond to anthropogenic change
 and management strategies.

File List: Note: all files in the data repository must be present in your working directory in order for the food web visualization and summary code to run. DATA FILES *nodes.csv* - a node list with metadata representing all known California rocky intertidal taxa and their life stages, where appropriate *links.csv* - a link list with metadata representing all trophic interactions known or inferred between nodes in the California rocky intertidal, including parasitism *references.csv* - a list of references used for assembling, justifying, and generating confidence rankings for nodes and links within the web *column_descriptors.csv* - a file containing column header and metadata code definitions R MARKDOWN FILES *cariz_foodweb_visualization.rmd* - Code for the visualization of the California rocky intertidal food web as a network graph and as a matrix. Includes code to generate commonly used metrics for a large network, including connectance, link density, mean degree, etc. *morton_zilz_node_merge.rmd* - Code to merge two very similar California food web datasets, this rocky intertidal food web and the Santa Barbara kelp forest food web described by Morton *et al.*, 2021. *example_web_subset_code.rmd* - Code designed to demonstrate how the nodes and links lists might be subsetted to reflect a sub-web of the larger metaweb. This example explains how to divide the metaweb into sub-webs reflecting the Oregonian Province rocky intertidal zone community and the Californian province rocky intertidal community. **METHODOLOGICAL INFORMATION** 1\.
