Hibernation the summer months is aestivation. Often associated with low temperatures, the function of hibernation is to conserve energy when sufficient food is unavailable. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months depending on the species, ambient temperature, time of year, and the individual's body condition. Before entering hibernation, animals need to store enough energy to last through the duration of their dormant period, possibly as long as the entire winter. Larger species become hyperphagic, eating a large amount of food and storing the energy
Politics of the Arizona Borderlands is on foot through the Sonoran Desert. The trek takes upwards of three days and immigrants face a host of issues while making it. Near the border, temperatures rise into the triple digits during the daytime in the summer months and fall to near freezing during the nighttime in the winter months. Average annual precipitation varies along the border but can be as low as three inches, while rainfall during the North American Monsoon season can be surprising and deadly (resulting in the passing of the Stupid Motorist Law, for example). Immigrants attempting to cross the border frequently die making
