Description
Return flower*minutes exposure and divide by the supplied reference.
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 flower*minutes exposure and divide by the supplied reference.
When to use this tool
Use Flower Observation Exposure Factor when checking the stated observation support, exposure, sample or seasonal-gap convention.
How to use the tool and how it works
- Enter flowers, minutes, referenceFlowerMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read exposure, factor. Use the output convention below.
Require whole flowers>=0, nonnegative minutes and positive referenceFlowerMinutes. Return flower*minutes exposure and divide by the supplied reference.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| flowers | Flowers | Required. Safe integer; minimum 0. |
| minutes | Minutes | Required. Finite number; minimum 0. |
| referenceFlowerMinutes | Reference Flower Minutes | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| exposure | Flower count*minutes, in flower-minutes; not an observed visit count. | Required. Finite number. |
| factor | Factor | Required. Finite number. |

}Limitations and assumptions
- Flower-minute exposure is effort bookkeeping, not a count of visits or an estimate of pollinator benefit.
- 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.
