Description
Dominance percentage records the largest taxon's share of a counted assemblage.
Dominance percentage records the largest taxon's share of a counted assemblage.1
It summarizes abundance concentration without deciding which tied taxon should be singled out.
When to use Dominance Percent Top Taxon Calculator
Use this tool to apply the stated dominance percent top taxon calculator operation with an explicit input and unit basis.
How to use Dominance Percent Top Taxon Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualObservedTaxonCounts and run the tool.
- Read result.value using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualObservedTaxonCounts | Observed taxon counts, on the basis specified in the algorithm. | array of number | required; dense; align related rows as specified; further conditions in the algorithm |
Require a nonempty array of integer counts 0–10,000 and a positive total. Divide maximum count by total and multiply by 100.
dominance percent = 100 × max(counts)/Σcounts Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Largest taxon count as a percentage of total counted specimens. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
For a related operation, use Rarefaction Species Count at Standardized N Calculator. Rarefaction estimates expected observed taxon richness in a smaller sample drawn without replacement from a finite counted inventory.
For a related operation, use Dinosaur Bonebed Monospecificity Percent Checker. A focal taxon's specimen fraction measures its share of a taxonomically resolved bonebed inventory.
