Description
Measure one supplied ecological interaction duration.
Ecological records need explicit sampling units, detection states, effort denominators, interval geometry and trait/abundance bases. Nondetection differs from absence, and shared sampling-unit labels do not alone diagnose pseudoreplication. A one-axis overlap or single weighted contribution is only a limited component of a broader ecological analysis.
Measure one supplied ecological interaction duration.
When to use this tool
Use Species Interaction Observation Duration when you already have interactionStart, interactionEnd and need to measure one supplied ecological interaction duration.
How to use the tool and how it works
- Enter interactionStart, interactionEnd. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read observedDuration. Use the output convention below.
Require interactionEnd>=interactionStart; return end-start.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| interactionStart | Interaction Start | Required. Finite number. |
| interactionEnd | Interaction End | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| observedDuration | Observed Duration | Required. Finite number. |

}Limitations and assumptions
- No interaction is detected, taxa identified, effect estimated or observation adequacy assessed.
- 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.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review original survey records, sampling design, specimens and calibration definitions for an ecological conclusion. Use complete detection, population, community or process models as appropriate; local count rates and source labels do not infer unobserved states or ecological mechanisms.
