ParasiteGroupStructure: code and data to support and replicate "Understanding the role of parasites in food webs using the group model" (Michalska-Smith, Sander, Pascual, & Allesina 2018)

This repository contains the code, data, and results needed to replicate the findings in "Understanding the role of parasites in food webs using the group model".

The Data/ folder contains data from Dunne et al. 2013 (PLoS Biology), formatted for use in Sander et al.. The Results/ folder contains the results used in analyses (groupings, imbalance values, and imbalance p-values). The Code/ contains programs and scripts used in our analyses: the group model search algorithm, imbalance and p-value calculation, mutual information, and statistical analyses. More detailed information about the files is given in README files in repository subfolders. For a description of the methodology and results, please check out the paper.

Note that throughout, flags are used to distinguish between degree-corrected and uncorrected models. A 0 flag corresponds to the uncorrected model, and a 1 flag corresponds to the degree-corrected model. Similarly, there is a flag for whether or not concomitant predation is included. "Par" is used for no concomitant predation, and "ParCon" for concomitant predation.
