Description
We provide the source code and executables for Windows and Linux operating systems, and a short description of the program.

The
software program Colonize was
developed to estimate the range of colonizers
allowed to account for the observed allele frequencies in a sampled
focal
population given the observed allele frequencies in a sampled source
population. This is done by creating random samples based on source and
target
population samples and given a number of colonists, and comparing the
observed
differences in allelic composition with the difference between the
original
samples. In this way probabilities are calculated for the minimum and
maximum
number of individuals colonizing the focal population. These
probabilities can
then be combined in a joint probability for each number of colonizers.
There
are a few assumptions to be met: there is no gametic linkage
disequilibrium
among the analyzed loci, and there has been no substantial genetic
drift in
source nor target population between the time of colonization and the
moment of
sampling. The program is available in a Windows and Linux version
from [e-mail] and from the website http://bio.kuleuven.be/eco/colonize,
as well as in the Ecological Archives Supplements.
