TABLE 3A. Column descriptions for Links data sheet.

Column Number Column Name Column Description
1 Consumer Node ID The unordered nominal node specific ID number of the consumer in the interaction.
2 Resource Node ID The unordered nominal node specific ID number of the resource in the interaction.
3 Consumer Species ID The unordered nominal specifies ID number of the consumer in the interaction.
4 Resource Species ID The unordered nominal specifies ID number of the resource in the interaction.
5 Consumer Stage ID The ordered stage sepecific ID number of the consumer node.
6 Resource Stage ID The ordered stage sepecific ID number of the resource node.
  Consumer SpeciesStage ID The combined Species ID number and Stage ID number of the consumer, separated by the decimal point.
Resource Species Stage ID The combined Species ID number and Stage ID number of the resource, separated by the decimal point.
7 Link Type ID The unordered nominal numeric indication of the specific type of trophic interaction occurring and corresponding to the Link Type column.
8 Link Type The unordered nominal definition of a trophic interaction corresponding to the Link Type ID column. Link types are mutually exclusive.� We use the term �symbiont� after De Bary (1879), to refer to all mutuals, commensals and parasites for which a larger organism serves as the host to an intimate and durable interaction. We use 'host� to refer to the resource individual for all trophic interactions where the consumer is a symbiont and by convention a micropredator. We use �prey� to designate resource individuals when the consumer is not a symbiont or a micropredator.�� Not all links are trophic (e.g. commensal) and care must be taken to exclude these from analyses of food web structure.
9 Link Evidence A qualitative description of the evidence or rationale for including the trophic link in the web.
10 Link Evidence Notes A qualitative description of the link evidence source.
11 Link Frequency For observed links, the proportion of times that the link was observed (e.g., the proportion of consumer guts within which the resource species was present).�
12 Link N The number of consumers that were examined to detect this particular link.
13 Diet Fraction The fraction of the consumer's diet (e.g., in terms of biomass/year) comprised by the resource node.
14 Consumption Rate The rate at which the interaction occurs, explicitly expressed in numbers, biomass or energy per unit time.
15 Vector From The Node ID of the vector necessary for a parasitic feeding link to occur.� For instance, enter the Node ID for mosquito here if the link is malaria-human. If more than one vector can lead to this type of parasitism, there will be multiple rows repeated here, one for each prey type.� Note, in many cases, this will lead to duplicate links, which may need to be considered in analyses.
16 Prey From The Node ID of prey needed to be consumed for a particular parasite–prey interaction to occur (via trophic transmission).� If more than one prey can lead to parasitism, there will be multiple rows repeated here, one for each prey type.� Note, in many cases, this will lead to duplicate links, which may need to be considered in analyses.
