Direction: Higher is desirable ↑
Form: Point

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 successfully detected invertebrates belonging to 45 distinct families, which were nested within 22 different orders.

Metric Definition:

Number of invertebrate families detected via eDNA metabarcoding (COI + 16S rRNA assays)

Benchmark Definition:

This benchmark represents the number of invertebrate families detected via eDNA metabarcoding in a well-managed conservation area within the Arid Mountain Ranges biome, reflecting a robust and informative taxonomic level for biodiversity assessment.

Justification:

The benchmark is based on a direct field measurement from a well-managed conservation area using comprehensive metabarcoding assays, representing the best available condition.

Notes

This value reflects the "best available condition" for a keystone habitat in the Arid Mountain Ranges biome. The benchmark is a point representing a high-functioning, complex, and resilient system. The upper detrimental threshold is compositional, not numerical, triggered by detection of invasive species rather than total richness.
