Table 1 Ecosystem indicators applied to the food webs
From: Fisheries impact on the East China Sea Shelf ecosystem for 1969–2000
Indicator | Definition |
|---|---|
Q | Total consumption flows in the ecosystem |
TR | Total Resprision |
FD | Total flow to detritus |
TST | Total system throughput, sum of all flows in the food web |
TLc | Mean trophic level of catch |
GE | Gross efficiency of fishery |
Npp | Net primary production |
Tpp/TR | Total primary production/total respiration |
NSP | Net system production |
PP/TB | Primary production/total biomass |
SOI | System omnivory index |
FCI | Finn’s cycling index |
FMPL | Finn’s mean path length |
A | The ascendency scaled by TST (related to the average mutual information in a ecosystem) |
O | Fraction of internal flows of overhead (used as an indicator of ecosystem redundancy) |
