Column Description |
|
|
1 |
NodeID |
The unordered nominal node
specific ID number of the discrete species lifecycle stage. |
|
|
2 |
SpeciesID |
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 |
StageID |
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 |
SpeciesStageID |
The unique nominal numeric code
for a node that combines Species ID and Stage ID, which are separated by a
decimal point. |
|
|
6 |
WorkingName |
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 |
OrganismalGroup |
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 |
NodeType |
The most specific level on which
a particular node is built. |
|
|
9 |
NodeResolution |
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 |
ResolutionNotes |
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 |
LifestyleStage |
An unordered enumerated
description of the intimacy a particular species' lifecycle stage has with
other organisms. ÔSymbiosisÕ 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 |
LifestyleSpecies |
An unordered enumerated
description of the intimacy a particular species has with other
organisms. |
|
|
14 |
ConsumerStrategyStage |
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. |
|
|
16 |
HabitatAffiliation |
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 |
NativeStatus |
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 |
BodySizeEstimation |
The unordered enumerated
description of the method used to quantify body size. |
|
|
22 |
BodySizeNotes |
Notes on the method used to
calculate the body size for a particular node in a particular system. |
|
|
23 |
BodySizeN |
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 |
BiomassEstimation |
An unordered enumerated
description of the method used to quantify the biomass of a particular node
in a particular system. |
|
|
26 |
BiomassNotes |
Notes on the method used to
quantify the biomass for a particular node in a particular system. |
