nematode_mammal — Global helminth–host associations (NHM, 2018)
- Description
Global network of host–parasite associations between helminth parasites and their host species, obtained with the R package helminthR (T. Dallas), which queries the Host-Parasite Database of the Natural History Museum, London, a compilation of host–parasite records from the published literature. The data were used by T. Dallas and collaborators to examine macroecological patterns in helminth parasites, and were distributed as a demonstration network by C. J. Carlson. The data are not restricted to nematodes and mammals (as the name of the dataset suggests): the parasites are trematodes, nematodes, cestodes and acanthocephalans, and the hosts include fish, birds, mammals, reptiles, amphibians and invertebrates.
Nodes are host and parasite species (the network is bipartite), and an edge connects a host to a parasite recorded on it. Each edge corresponds to one record of the database, which lists the locality of the record, so a host–parasite pair recorded at several localities is connected by several parallel edges (the 146,683 edges connect 61,597 distinct pairs).
The network has the following properties:
- (Node)
name: the species name of the host or parasite. - (Node)
is_host: whether the node is a host (otherwise it is a parasite). - (Node)
group: for parasites, the parasite group (Trematoda, Nematoda, Cestoda or Acanthocephala); for hosts, the host group (e.g. Teleostei, Aves, Mammalia, or NA if not available). - (Edge)
full_name: the full name of the parasite with taxonomic authority, as given in the record (it can vary between records of the same parasite, e.g. for synonyms or subspecies). - (Edge)
locality: the locality of the record.
