Equation 3: Make northward migration survival matrix (S.m)

Description

This function produces a diagonal matrix of northward (spring) migration (.m) survival rates

Usage

eq03buildW2Mat(S.m.mg = 0.75, S.m.mp = 0.75, S.m.fg = 0.75, S.m.fp = 0.75)

Arguments

S.m.mg	Survival (S.) during migration (.m.) of males (.m) originating from good (g) habitat
S.m.mp	Survival on migration of males originating from poor (p) habitat.
S.m.fg	Migration survival of female birds (f) from good habiatat
S.m.fp	Migration survival of females from poor habitat

Value

S.m (aka W2) Matrix of spring migration (m) survival probabilites by sex and winter habitat the bird originated from
