Merriam's kangaroo rats obtain enough water from the metabolic oxidation of the seeds they eat to survive and do not need to drink water at all. [11] To help conserve water they produce very concentrated urine, via a process apparently associated with expression of aquaporin 1 along a longer than usual segment of the descending limb of the loop ...
Kangaroo rats lose water mainly by evaporation during gas exchange, and so have developed a behavioural adaptation to prevent this loss. As they spend a lot of time within their burrows to escape the heat of the day, the burrows become much more humid than the air outside (due to evaporative loss).
Ord's kangaroo rat (Dipodomys ordii) is a kangaroo rat native to western North America, specifically the Great Plains and the Great Basin, with its range extending from extreme southern Canada to central Mexico. [2] [3] Ord's kangaroo rat has a fifth toe on its hip feet, which distinguishes it from Dipodomys elator. It is bicolored with gold ...
The desert kangaroo rat (Dipodomys deserti) is a rodent species in the family Heteromyidae that is found in desert areas of southwestern North America. [2] It is one of the large kangaroo rats, with a total length greater than 12 inches (300 mm) and a mass greater than 3.2 ounces (91 g).
Dipodomyinae is a subfamily of heteromyid rodents, the kangaroo rats and mice. Dipodomyines, as implied by both their common and scientific names, are bipedal ; they also jump exceptionally well. Kangaroo rats and mice are native to desert and semidesert ecosystems of western North America from southern Canada to central Mexico .
Phillips's kangaroo rat (Dipodomys phillipsii) is a species of rodent in the family Heteromyidae. [3] It is endemic to Mexico.Its natural habitat is hot deserts. The species is named after John Phillips, an official of a Mexican mining company who sent zoological specimens, including the type specimen of this kangaroo rat, to the British Museum.
The banner-tailed kangaroo rat feeds on seeds and other parts of plants, most notably grass seeds in the form of whole seed-heads. It caches surplus food in its burrow, and is the most assiduous hoarder among the kangaroo rats. In a research study where the rats were fitted with radio-tracking equipment, individuals had a home range of about ...
The Heermann's kangaroo rat does not hibernate, instead it remains more or less active during the year depending on time of day. [5] It lives in a burrow for the majority of the day (up to 23 hours/day) and typically only comes out at night. Rain, fog and a bright full moon will usually prevent them from coming out of their burrow. [10]
