eDNA Biodiversity Detection

AUS-TMI-AQU-DNA General Low confidence

Benchmark Value

No specific value — see range
Direction: Higher is desirable ↑
Form: CompositeFramework

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is CompositeFramework, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

An eDNA profile is considered to have crossed this threshold and to represent a detrimental state if it exhibits one or more of the following: Confirmed detection of one or more high-risk, non-native invasive species not previously known from the area.

Metric Definition:

eDNA Biodiversity Detection (Compositional Profile)

Benchmark Definition:

An upper detrimental threshold indicating system imbalance in aquaculture, identified by the presence of high-risk, non-native invasive species detected via eDNA.

Justification:

High species richness can be a negative indicator if it includes invasive species, pathogens, or indicators of eutrophication.
