For the fact that they are so abundant in nature, these mice constitute a large component of the nearctic ecosystems. These mice have also been of very great importance to the scientific esearch, both the wild type and the genetically variant have been used for laboratory researches. They do differ from the house mouse and the rats, because they are not closely related to these species.
