Lefkovitch matrix model A representing transition of a female-only, pre-breeding, chronic wasting disease-structured 4 x 4 matrix of a mule deer population in southern Converse County, WY using demographic and disease rates observed from 2010–2014.
nt represents the number of deer in each age class by CWD status (-; PrPCWD not detected and +; PrPCWD detected). represents estimated survival of CWD-negative or CWD-positive deer and
is the estimated fawn survival from mid-December to mid-June.
represents CWD incidence,
is the estimated pregnancy rate, and
is the estimated recruitment rate determined in November.
