Heteromyidae is a family of rodents consisting of kangaroo rats, kangaroo mice, pocket mice and spiny pocket mice.Most heteromyids live in complex burrows within the deserts and grasslands of western North America, though species within the genus Heteromys are also found in forests and their range extends as far south as northern South America.
The pups are born in burrows lined with leaves, roots and hair. They are well developed at birth and may be up and eating within an hour. Fathers are barred from the nest while the young are very small, but the parents pair bond for the rest of their lives. They can live for as long as 20 years, a remarkably long time for a rodent. [9]
Gundis or comb rats (family Ctenodactylidae) are a group of small, stocky rodents found in Africa.They live in rocky deserts across the northern parts of the continent. The family comprises four living genera and five species (Speke's gundi, Felou gundi, Val's or desert gundi, common or North African gundi and Mzab gundi), as well as numerous extinct genera and species.

Perognathinae is a subfamily of rodents consisting of two genera of pocket mice.Most species live in complex burrows within the deserts and grasslands of western North America, They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches [2] to their burrows.
In the 1970s, researchers removed kangaroo rats from an ecosystem in the Chihuahuan Desert, and for many years, no other small rodents moved in to fill the niche they left. In 1995, twenty years after the experimental removal, Bailey's pocket mouse moved into the area and filled the gap, almost completely replacing the missing kangaroo rats.
Desert woodrats are relatively small for pack rats, measuring 28 to 39 cm (11 to 15 in) in length, including a 12 to 20 cm (4.7 to 7.9 in) tail. They weigh from 122 to 350 g (4.3 to 12.3 oz), with males being larger than females. Their coloring varies between individuals, and can be anything from pale gray to cinnamon to near-black.
Voles thrive on small plants yet, like shrews, they will eat dead animals and, like mice and rats, they can live on almost any nut or fruit. In addition, voles target plants more than most other small animals, making their presence evident. Voles readily girdle small trees and ground cover much like a porcupine. This girdling can easily kill ...
Kangaroo rats, small mostly nocturnal rodents of genus Dipodomys, are native to arid areas of western North America.The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo, but developed this mode of locomotion independently, like several other clades of rodents (e.g., dipodids and hopping mice).
