    "abstract": "We study the effect of mutations in a simple model of colonization, based on\nMontecarlo simulations. When the population colonizes the whole available\nhabitat, a maximum population density is reached, which depends on the mutation\nrate. Depending on the values of other parameters, such as selection pressure,\nfecundity and mobility, there is an optimal value for the mutation rate for\nwhich the colonization reaches the highest density. We also investigate the\nsurvival probabilities under different conditions and its relation to the\nmutation rate.",
