Combined host and parasite records

occurrence information for both parasites and their hosts off the Global Biodiversity Information Framework (GBIF: The Global Biodiversity Information Facility, 2021) and the Ocean Biodiversity Information System (OBIS, 2021).

Records with missing data points, missing coordinates and duplicates were removed. To account for any geographic outliers, I removed any records where the minimum distance of that record to all other records, was greater than 10 degrees. Additionally, the high-resolution coastal layer from the Global Self-consistent, Hierarchical, High-resolution Geography Database (GSHHG) (Wessel & Smith, 1996) was used to remove land-based occurrence points with a one kilometre buffer. This buffer was used to account for historical changes in coastline points.
