Troglobite Endemism Index Assemblage Scorer

Actual independently qualified cave assemblage known-endemic taxon percentage, unknown taxonomy/endemism retained. Not abundance-weighted biodiversity, true global endemism or species identification.

Description

Endemism describes the geographic restriction of independently identified taxa.

Endemism describes the geographic restriction of independently identified taxa.^[1]

An assessed troglobite inventory must retain unresolved taxonomy or endemism separately from known endemic counts.

When to use Troglobite Endemism Index Assemblage Scorer

Use this tool to obtain knownEndemicTaxonCount, knownAssessedTaxonCount, knownEndemicTaxonPercent, unknownTaxonIds from the supplied records using the stated calculation. Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.

How to use Troglobite Endemism Index Assemblage Scorer and understand its results

Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
Enter actualAssessedTroglobiteTaxonIds, independentlyQualifiedEndemicFlags, endemismEvidenceKnownFlags, using the field meanings and rules below, then run the tool.
Read result.knownEndemicTaxonCount, result.knownAssessedTaxonCount, result.knownEndemicTaxonPercent, result.unknownTaxonIds. Use the units and sign conventions below, and review any unknown records separately.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
actualAssessedTroglobiteTaxonIds	Actual assessed troglobite taxon ids	list of string	Required
independentlyQualifiedEndemicFlags	Independently qualified endemic flags	list of number	Required
endemismEvidenceKnownFlags	Endemism evidence known flags; binary 1 means the matched observation is known, 0 means unknown	list of number	Required

Supply nonempty unique nonblank taxon IDs with aligned binary endemic flags and evidence-known flags. At least one taxon must be known. Count known endemic taxa and known assessed taxa, return their percentage and list unknown taxon IDs in supplied order. Unknown endemism does not contribute to the known denominator.

knownEndemic=Σ(endemic_i×known_i); knownAssessed=Σknown_i; knownEndemicPercent=100×knownEndemic/knownAssessed

Use the matching field units and the exact boundary, ordering and reference rules above.

Output field	Meaning	Value type
result	Qualified observed calculation or explicit reference	object
result.knownEndemicTaxonCount	Number of taxa both marked known and independently coded endemic.	number
result.knownAssessedTaxonCount	Number of taxa marked known in the assessed inventory.	number
result.knownEndemicTaxonPercent	Known endemic taxa divided by known assessed taxa times 100.	number
result.unknownTaxonIds	Taxon identifiers with unknown endemism evidence, in supplied order.	list

Limitations and assumptions

The actual observation coverage, calibration and qualified plan determine applicability. A numerical result does not establish survey accuracy, route suitability, atmosphere conditions or equipment adequacy beyond the declared comparison.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. String lists allow at most 128 entries of at most 128 UTF-16 units each; blank and duplicate rules are stated above. Extremely large composite outputs are rejected.

Alternative or Complementary methods

For a related step, use Histoplasmosis Risk Guano Disturbance Flag Checker: A guano-disturbance and airborne-dust record can support a qualified exposure review. For a complementary comparison, use Bat Guano Pile Volume Estimate Calculator: An elliptical-cone approximation relates two base semiaxes and pile height to a geometric volume.
