Impact of Red Fox Predation on the Sex Ratio of Prairie Mallards

Table 2: Relationships Among Components of the Model

Table 2. Relationships among components of the model. Unless otherwise specified, the index is assumed to be time in years, e.g. X1 is interpreted as X1(t).
F exogenous
PM exogenous
PF(t) = SF(t-1) + RF(t-1); initially PF(1) = PM(1)
SM = r3PM
SF = r4PF
FM = r1F
FF = r2F
OM = r9(PM-FM)
OF = r10(PF-FF)
HM = r5(PM-FM-OM)
HF = r6(PF-FF-OF)
WM = r11(PM-FM-OM-HM)
WF = r12(PF-FF-OF-HF)
RM(t) = PM(t + 1) - SM(t)
RF = r13RM
