Of the nine taxa listed by Reynolds and Lindsay (1999) as being "restricted temporally" to either the Hemphillian or Blancan land mammal ages, only two (Peromyscus valensis and Dipodomys
gidleyi) are definitively identified to species.
In a study comparing rodent communities in grassland and mesquite coppice dune habitats (locations used in this study), Alberico (1978) found that Dipodomys
ordii was the most abundant species in both habitats.
Aboveground activity of Merriam's kangaroo-rats (Dipodomys
merriami) in relation to sex and reproduction.
Randall (1989a) described behavior of Merriam's kangaroo rats (Dipodomys
merriami) in the field in neighbor-recognition experiments.
Quadrupedal pocket mice (Perognathus and Chaetodipus) and bipedal kangaroo rats (Dipodomys
) are morphologically similar to quadrupedal gerbils (Gerbillus) and bipedal jerboas (Jaculus), respectively.

Kangaroo rats (Dipodomys
spp.) will manipulate seeds in their caches by handling the seeds and even urinating on them in order to reduce spoilage from fungi (Reichman and Rebar, 1985; Reichman et al., 1986).

This injury, which commonly occurs to long-tailed rodents (e.g., Dipodomys
spp.) when caught in box live traps, is a methodological problem.
For example, bipedal kangaroo rats (Dipodomys
spp.) and kangaroo mice (Microdipodops spp.) are often associated with open (Rosenzweig, 1977; Price and Brown, 1983), and disturbed (Mellink, 1985; Stangl et al., 1992) areas.

By offering 40-g piles of fluorescently labeled Indian ricegrass seeds on trays, Longland and Clements (1995) found that mean cache sizes of heteromyids (mainly Dipodomys
merriami) ranged from approximately 90 to 170 seeds.

However, only the following five species have been reported: Cratogeomys castanops, Perognathus flavescens, Dipodomys
ordii, Chaetodipus eremicus and Lynx rufus (cf.
