KR Carrying capacity of transmission hosts per month (t) (6(10+(cos(2π(t/12+0.35)))/3)220sin(2π(t/12+0.35)))SR
mR Mortality rate of transmission hosts per month (t) (8+2/KR(t))/52
KD Carrying capacity of reproduction hosts (per kilometer squared) 300SD
MC Movement capacity (km/month)
Reproduction hosts in home ranging phase 2.2 (winter/spring); 1.5 (summer/fall)
Reproduction hosts in migration phases 8.5
pT Time spent in different habitat types (% of time step)
Home ranging transmission hosts in forests, shrubs, and grassland 60, 30, 10
Home ranging reproduction hosts in forests and shrubs 85, 15
Grazing reproduction hosts in grassland 35
rpG Proportion of reproduction hosts venture for grazing (%) See “Host movement” section

Note: SD, habitat suitability for reproduction hosts; SR, habitat suitability for transmission hosts.
