Procedure for using "Maps"

• Under the MAIN MENU - choose Toolkits
• Under the TOOLKITS MENU - choose Maps
• Under Systems Ops - choose Create System
• Select Variables - u v w x
• Select Paramters - b d
• u(t+1)=20*u/21+0.672*b*log(w+1)
• v(t+1) = u/21 + 20*v/21
• w(t+1) = v/21 + (1-d)*w
• x(t+1) = u + v + w (x(t) will keep track of the population total.)
• Final t = 30
• For u(0), v(0), and w(0) enter the initial brood, house bee, and forager population in thousands. For x(0) enter the sum of the other three.
• b = brood score
• d = fraction deaths
• Under Plot Ops - choose Plot in 4 windows.
• Window 1 variables: t u
• Window 2 variables: t v
• Window 3 variables: t w
• Window 4 variables: t x
• Accept - choose No
• Change Minimum u, v, w, x to 0.
• Change Maximum u, v, w, x appropriately. Remember that x is the sum of u, v, and w.
• Use CNRL(X), CNRL(L), or CNRL(D) to chart month.
• At the end Under Disk Ops - choose Save System to use again.
