disp_rate_max: Maximum limit on dispersal speed for migration model

In robjohnnoble/demonanalysis: Analysis and plotting of demon data

Description

Maximum limit on dispersal speed for migration model

Usage

disp_rate_max(K, m, r1, r2, migration_type = 0, symmetric = FALSE,
  two_dim = TRUE, d = NA)

Arguments

K	deme carrying capacity
m	migration rate per cell, relative to birth rate
r1	birth rate of cells in the destination deme, relative to reference birth rate
r2	birth rate of migrating cells, relative to r1
migration_type	0 or 1 (see details)
symmetric	whether migration occurs in both directions
two_dim	whether to adjust for two-dimensional growth
d	migration distance relative to 1/sqrt(K); if NA then d is set to sqrt(K)

Details

Assumes that the time until fixation is negligible relative to the time until migration.

Meaning of migration_type:

• 0: migration, such that a migration attempt occurs only following a birth event

• 1: migration, such that migration is independent of birth

Value

The upper limit on the growth rate of the radius, measured in cells (not demes).

Examples

disp_rate_max(2, 0.1, 1, 1.1, 0)
disp_rate_max(2, 0.1, 1, 1.1, 1)
