Such studies would provide a better idea of how plastic response differ across population and species, and whether our findings can be broadly generalized to other organisms. Another, the woodland deer mouse, is found in forests of the northern Lower Peninsula and the Upper Peninsula. Sea-level and high-altitude breeding colonies of Peromyscus maniculatus sonoriensis. These mice possess evolutionary adaptations to high altitude such as the aforementioned hemoglobin polymorphisms. Particularly in the case of the run in hypoxic conditions, the importance of the lung as a predictor of aerobic performance seems evident.
The prairie form will also make large stores of seeds in burrows for the winter months. Peromyscus have a much longer lifespan than typical lab mice, making them useful for many forms of research. By the second day their skin gains color and is no longer transparent.
