CCAMLR predator-prey-environmental index

AWAITING REVIEW

Indicator summary

Summary of indicator structure and function

Definition and/or background

The following is from Fulton et al 2004a -

The CCAMLR Ecosystem Monitoring Program involves a wide range of measure designed to indicate the status of a number of species and environmental features (de le Mare and Constable 2000). However, for ease of interpretation, a single index is desirable and so the CCAMLR predator-prey-environment index was created. Thus, the CCAMLR predator-prey-environment index is similar in principle and function to an IBI, but its derivation has been dealt with far more formally with regard to the theories of multivariate statistics. Unfortunately, as yet its value has yet to be tested with real datasets, though an investigation of its robustness to missing data has been undertaken using Monte Carlo simulations (de le Mare and Constable 2000).  

Attribute

Community structure and function, Trophic structure, Habitat structure and condition

Purpose

CCAMLR Ecosystem Monitoring Program (CEMP)

Taxa

Some penguins, seals, and flying birds that were selected as indicator species by CEMP.

Data required

The following is from Fulton et al 2004a -

Data for any selected metric to be included in the final summary index, e.g. biomass; density; diversity; abundance; recruitment; abiotic measures etc

Ecosystem applicability

The following is from Fulton et al 2004a -

Potentially applicable for any marine system, but it needs testing. Currently being considered for CCAMLR ecosystems.

Robustness

The following is from Fulton et al 2004a -

Potentially high: its advantages are that it is a single “user friendly” index that summarises a lot of biological and physical information. Its disadvantages are that it is affected by missing data if the time-series are not highly correlated (>0.6). However, criteria for determining appropriate parameters for inclusion in the index and a procedure for checking for anomalies have been proposed and are being tested (de le Mare and Constable 2000).
