TABLE 2A. Column descriptors for Nodes data sheet.
| Column Number | Column Header | Column Description |
| 1 | Node ID | The unordered nominal node specific ID number of the discrete species lifecycle stage.�� |
| 2 | Species ID | The unordered Species ID number.� This is independent of Node ID number and is consistent across nodes depicting different lifecycle stages of the same species.� If one wishes to combine across life stages they can substitute this number for the Node ID in analyses. |
| 3 | Stage ID | The ordinal Stage ID number within species.� Adult lifecycle stages are designated as 1.� The youngest lifecycle stage is then 2, next youngest 3, etc.� Each number corresponds to a particular lifecycle stage that is consistent within a group but not between them (e.g. for trematodes 2 = parthenitae, but for dipterans 2 = larvae).� Not all of a species' lifecycle stages are necessarily present a particular food web. |
| 4 | Stage | The unordered nominal description of the lifecycle stage code that is consistent within a particular group. |
| 5 | Species Stage ID | The unique nominal numeric code for a node that combines Species ID and Stage ID, which are separated by a decimal point. |
| 6 | Working Name | A working name for each node that is intended to be informative and useful.� When available, widely used common names were employed. If no common name exists then a species name was used. If no species name was available, then a working or descriptive name was employed. |
| 7 | Organismal Group | A category broader than 'Working Name' primarily intended be informative, particularly in letting the user know "what kind" of organism a particular node is. |
| 8 | Node Type | The most specific level on which a particular node is built. |
| 9 | Node Resolution | The lowest level that a node represents (e.g. Family, Species). A species does not need to be identified to a species binomial in order to be treated as a discrete species. |
| 10 | Resolution Notes | Notes on node resolution (e.g. if a single node is suspected of being a cryptic species complex). |
| 11 | Feeding | A designation as to whether a node is feeding or non-feeding.� Autotrophs are considered non-feeding as are certain metazoan lifecycle stages. |
| 12 | Lifestyle Stage | An unordered enumerated description of the intimacy a particular species' lifecycle stage has with other organisms. �Symbiosis� is used here in the original sense of De Bary (1879), referring to interspecific intimate and durable associations, including both positive and negative interactions among the partners. |
| 13 | Lifestyle Species | An unordered enumerated description of the intimacy a particular species has with other organisms.� |
| 14 |
Consumer Strategy Stage |
The unordered enumerated description of the general consumer strategy of a particular species lifecycle stage.� It should describe the majority (usually all) of the trophic interactions of a particular consumer.� |
| 15 | System | An unordered enumerated characterization of the system where the node is present, if multiple systems are included in the analysis.� While node ID numbers remain consistent between systems biomass will vary between systems.� This column is not present in the individual estuarine webs. |
| 16 | Habitat Affiliation | An unordered enumerated characterization of the habitat zone or type where the organism is found. Example: a bivalve may be in the soft-sediment or benthos. |
| 17 | Mobility | An ordinal characterization of the short-term vagility of organisms in the system.� |
| 18 | Residency� | An unordered enumerated characterization of the long-term vagility �of the free-living nodes (excluding micropredators) in the system. |
| 19 | Native Status� | An unordered enumerated characterization of whether or not an organism is native or non-native� to the system. |
| 20 | BodySize (g) | The mean body size (grams wet weight, soft & hard parts) of an individual node. If units vary, a separate BodySizeUnits column can be employed. |
| 21 | Body Size Estimation | The unordered enumerated description of the method used to quantify body size. |
| 22 | Body Size Notes | Notes on the method used to calculate the body size for a particular node in a particular system. |
| 23 | Body Size N | The number of individuals that were sampled to estimate average body size. |
| 24 | Biomass (kg/ha) | The average biomass per area (kilograms/hectare) of a particular node in a particular system. Count density can be logically derived from biomass and body size. |
| 25 | Biomass Estimation | An unordered enumerated description of the method used to quantify the biomass of a particular node in a particular system. |
| 26 | Biomass Notes | Notes on the method used to quantify the biomass for a particular node in a particular system. |
