Table VIII-5.	Influence of variability upon the effects of dispersal activity The same situations 1a - 2b as in Table VIII-4:
Q1, Q2 =	survival in first and second season respectively
0, 101,..,>104 =	mean number of populations after 25 years with sizes of 0, 1-101,101-102..,>104
Rg =	geometric mean of net reproduction values = (Pn/P0)/n), if P0 = starting size (= 20*500=10000), and n = last year the species was present in the area (n<26)
v.c.Rg =	variation coefficient of Rg
LR =	log(H) - log(L), if H and L are the highest and the lowest population size observed, respectively
v.c. =	variation coefficient of the mean values used in the simulations
B =	simulation of species B (no dispersal)
M =	simulation of species M (with dispersal)
