Document Summary

All populations have the potential for exponential (malthusian) growth. Doubling time: td = r/ln(2), tripling time: td = r/ln(3) Nt+1 = nt + nt * rd = nt (1+rd) = nt er = . Intrinsic growth per capita = r = ln . Population decrease: 0 < < 1, r < 0. Tribbles are doubling in their population at every time step. What is the intrinsic rate of increase with the tribbles? r = ln = 0. 69. N2 = n 1 = ( n 0)
