speciesGestation: Per-species reproductive parameters

In nprcgenekeepr: Genetic Tools for Colony Management

Per-species reproductive parameters

Description

A lookup table mapping a species name to reproductive parameters used across the package. It keys the gestation window in getPotentialParents through getSpeciesGestation and the minimum breeding ages in the Genetic Value Analysis unknown-parent mean-kinship correction through getSpeciesMinBreedingAge. Species names are matched case- and whitespace-insensitively; any species not present falls back to 210 days for gestation and 2 years for the breeding ages. Rhesus gestation is 210 days (the historical conservative bound; typical rhesus gestation is about 165 days, per Vinson & Raboin 2015), and rhesus minimum breeding ages are male = 4, female = 2.5. The table is populated for the common colony NHP species, with gestation values as conservative upper bounds; making the values user-configurable is a separate planned enhancement. Extend or adjust it by editing data-raw/speciesGestation.R and re-running that script.

species

– character species name (e.g. "RHESUS").

gestation

– integer maximum gestation period in days (a conservative upper bound).

minMaleBreedingAge

– numeric minimum age in years at which a male of the species can sire offspring.

minFemaleBreedingAge

– numeric minimum age in years at which a female of the species can bear offspring.

Usage
