Description
Return max(0,nextStart-firstEnd) and a season-clipped gap using min(nextStart,seasonEnd).
Ecological observation summaries depend on sampling effort, eligible time, classified counts and missingness policies. Flower-minutes, area-days and observed proportions have different denominators. Observation support is distinct from true abundance, detection probability or a causal biological-control effect.
Return max(0,nextStart-firstEnd) and a season-clipped gap using min(nextStart,seasonEnd).
When to use this tool
Use Floral Resource Seasonal Gap Duration when checking the stated observation support, exposure, sample or seasonal-gap convention.
How to use the tool and how it works
- Enter firstFloweringEnd, nextFloweringStart, seasonEnd. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read gap, withinSeasonGap. Use the output convention below.
Require firstFloweringEnd<=seasonEnd. Return max(0,nextStart-firstEnd) and a season-clipped gap using min(nextStart,seasonEnd).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstFloweringEnd | First Flowering End | Required. Finite number. |
| nextFloweringStart | Next Flowering Start | Required. Finite number. |
| seasonEnd | Season End | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| gap | Gap | Required. Finite number. |
| withinSeasonGap | Within Season Gap | Required. Finite number. |

}Limitations and assumptions
- No lower season boundary or flowering observation is inferred; overlapping periods produce zero gap.
- 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
Use verified representative field records and suitable sampling/detection analysis for ecological inference, uncertainty and management.
