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 Species Stage 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. |
