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 Joost.vanoverbeke@bio.kuleuven.be and from the website http://bio.kuleuven.be/eco/colonize, as well as in the Ecological Archives Supplements.
