Flea Comb Capture Yield
Summarize adult flea captures per comb pass and per examined animal.
Description
Flea-comb capture counts can be pooled by pass and normalized by the number of animals examined.
Flea-comb capture counts can be pooled by pass and normalized by the number of animals examined. These denominators describe collection effort differently.
The tool returns totalCaptured (total captured); meanPerPass (mean per pass); capturedPerAnimal (captured per animal). Input measurements and model parameters are supplied by the caller; the tool computes the stated summary rather than acquiring those measurements.
When to use Flea Comb Capture Yield
Use Flea Comb Capture Yield when you already have combPassCounts, totalExaminedAnimals and want totalCaptured, meanPerPass, capturedPerAnimal. This is useful for checking a supplied calculation, documenting a measurement convention, or comparing observations prepared on the same basis.
How to use Flea Comb Capture Yield and understand its results
- Enter combPassCounts, totalExaminedAnimals using the field table below. Match the units, ordering and data boundaries described in the calculation.
- Run the tool after checking the stated bounds and matching paired observations or categories. A malformed request gives a tool error rather than a usable measurement.
- Read totalCaptured, meanPerPass, capturedPerAnimal. Use the calculation and interpretation below to distinguish amounts, ratios, signs and decision flags where applicable.
- Review the supplied parameters and assumptions before using the result in a report or comparing it with another observation.
| Input field | Meaning | Value type and bounds | Requirement |
|---|---|---|---|
| combPassCounts | Comb pass counts | list of number | Required |
| totalExaminedAnimals | Total examined animals | integer | Required |
Sum a nonempty list of nonnegative integer captures, dividing by the list length and the positive integer animal count.
total = Σcaptures; mean per pass = total/passCount; per animal = total/animalCount The symbols refer to the supplied quantities or generated values described above; unit conversions and comparison boundaries follow the stated implementation.

}Limitations and assumptions
The list represents passes, not necessarily one entry per animal. Duration, animal size and capture efficiency are not standardized by the calculation.
Numerical inputs must be finite. The tool checks its declared input shape and calculation constraints; those checks do not verify the quality, calibration or representativeness of the supplied observations.
