Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
As a whole the female jumping mouse is slightly larger, and heavier than the male, but their weight varies quite a bit depending on the season. Their weight during summer seasons can range from 11.15 grams to 24. 8 grams, with an average at about 16 to 19 grams. Just prior to hibernation, jumping mice can obtain a weight of 35 grams or larger. [5]

The wood mouse (Apodemus sylvaticus) is a murid rodent native to Europe and northwestern Africa. It is closely related to the yellow-necked mouse (Apodemus flavicollis) but differs in that it has no band of yellow fur around the neck, has slightly smaller ears, and is usually slightly smaller overall: around 90 mm (3.54 in) in length and 23 g in weight.

The mating season occurs in May, with gestation about 29 days to three to six pink-skinned and hairless young. The eyes open about the 26th day, weaning occurs about the 30th day, and by the 34th the young look like adults. The mating season for the woodland jumping mouse starts at the beginning of summer (May) and ends at the end of summer ...
They can hibernate six months out of the year, or even longer if the weather does not become warm enough, sometimes waking for brief periods to eat food they had previously stored nearby. During the summer, they accumulate fat in their bodies to nourish them through the hibernation period.
Needing more sleep during the winter may also be due to what’s known as “social jet lag,” experts said, meaning that the fun, late nights you had all summer may be why you’re having ...
Mice are good jumpers, climbers, and swimmers, and are generally considered to be thigmotactic, i.e. usually attempt to maintain contact with vertical surfaces. [citation needed] Mice are mostly crepuscular or nocturnal; they are averse to bright lights. The average sleep time of a captive house mouse is reported to be 12.5 hours per day.
