Robustness

The following is from Fulton et al 2004a -

Medium to high: assuming taxonomic resolution and diet composition data is reliable, trends in SOI could be very informative. However, diet composition and sufficient taxonomic resolution of the data are not always present and thus the trophic structure of the models used to derive SOI can have a large influence on the resulting values. Once the true magnitude of this model structure issue has been investigated, or data resolution is of a sufficient grade, SOI should be a useful indicator.

Stakeholder/Public acceptability

Acceptability with stakeholders?
* by all stakeholder
* by the public
* understandable to the stakeholders
