Description
Count presences with and without sampling support.
Biodiversity summaries depend on taxon concepts, sampling effort, detection and missing-status policies. Literal labels and observed shares can organize records while species identity, true abundance, occupancy and conservation status require appropriate ecological evidence and analysis.
Count presences with and without sampling support.
When to use this tool
Use Taxon Incidence Support Count when checking the stated biodiversity record, effort, count or support convention.
How to use the tool and how it works
- Enter observed, sampled. Follow any array-alignment requirements below. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read supportedPresences, unsupportedPresences. Use the output convention below.
Count presences with and without sampling support. Require aligned observed/sampled flags; supportedPresences requires both true, unsupportedPresences requires observed and not sampled.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| observed | Observed | Required. Array of boolean; maximum items 256. |
| sampled | Sampled | Required. Array of boolean; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| supportedPresences | Supported Presences | Required. Safe integer. |
| unsupportedPresences | Unsupported Presences | Required. Safe integer. |

}Limitations and assumptions
- Flags are assertions; no actual detection, survey adequacy or species occurrence is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use source-aware taxonomy, verified field records and a suitable sampling/detection model for ecological estimates, uncertainty or conservation conclusions.
