Individually resolved life stages

The copepodite stages plus the adult stage. Selecting these is unambiguous: they never overlap, so summing any subset counts each animal once.

Usage

single_stages()

Value

character vector of single-stage codes

Details

The database also holds combination columns spanning several stages (cfin_CV_VI, pseudo_CI_IV, ctyp_IV_VI, and the unstaged ctyp_C). Those are deliberately not offered for selection, because they overlap the single stages — summing CV together with CV_VI would count the same animals twice.
