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

The study provides a clear, quantitative result for fish diversity in this high-health system, stating, 'A total of 23 species were detected'.18

Metric Definition:

Species richness as the count of unique taxa detected via eDNA metabarcoding in aquatic ecosystems.

Benchmark Definition:

This benchmark represents the number of fish species detected by eDNA metabarcoding in a pristine tropical aquatic habitat, serving as a reference for biodiversity potential in aquaculture water systems within tropical and subtropical rainforests.

Justification:

This benchmark is based on a peer-reviewed eDNA metabarcoding study of a pristine tropical river, representing a 'best available natural condition' for aquatic ecosystems in the target biome.

Notes

No upper detrimental threshold — higher values are always better up to natural saturation. This proxy benchmark is proposed as a reference for the potential biodiversity that could be supported by well-managed water treatment/settlement ponds of a best-practice aquaculture facility, as no direct studies from such facilities exist. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
