The changing trends of

.
(a) As u increases, 
decreases for low v and high v (not shown), and exhibits an inverted U-shaped curve for moderate v. 
expands quickly as u increases. For very low u, 
is greater than 
(inset). For a little higher u, 
is smaller than 
, and the difference will expand quickly as u increases. (b) As u increases, 
expands nearly linearly with a high speed of around N. r leads to a negligible change of 
. (c) v or r results in a significant change of 
but a relatively negligible change of 
. A moderate v maximizes 
, and most values of v near 0 produce much larger 
than that of the well-mixed population (solid line). The value of r corresponding to the maximum value of 
varies with v (inset). (d) 
is maintained around a constant value (Nu) with the increase of v irrespective of M. Parameters: (a) v = 0.1, M = 7, N = 100; (b) v = 0.1, M = 7; (c) u = 0.018, M = 7, N = 100; (d) N = 100, r = 1.
