Identification of a novel polyomavirus in wild Sonoran Desert rodents of the family Heteromyidae
Archives of Virology, 2023Rodents are the largest and most diverse group of mammals. Covering a wide range of structural and functional adaptations, rodents successfully occupy virtually every terrestrial habitat, and they are often found in close association with humans, domestic animals, and wildlife.

Behavioural adaptations of desert rodents (Heteromyidae)
Animal Behaviour, 1993Abstract Abstract. Heteromyid rodents (kangaroo rats, Dipodomys spp.; kangaroo mice, Microdipodops spp.; pocket mice: Perognathus spp. and Chaetodipus spp.) make excellent models for answering questions about the evolution of diverse behaviour patterns.

Oecologia, 1990
Granivorous desert rodents of the family Heteromyidae forage nonrandomly among "microhabitats" that vary in substrate, seed densities, and seed species composition. To explore the hypothesis that microhabitat use is sensitive to seed patch profitability, we quantified effects of seed size (1.96 vs.

Chromosome Studies of Certain Pocket Mice, Genus Perognathus (Rodentia: Heteromyidae)
Journal of Mammalogy, 1967The somatic metaphase chromosome complements of seven species of pocket mice, genus Perognathus , subgenus Chaetodipus , were analyzed from dividing bone marrow cells. The species studied include P. penicillatus (2n = 46), P. pernix (2n=38), P. intermedins (2n = 46), P. goldmani (2n = 52), P. artus (2n = 54), P. baileyi (2n = 48), and P. hispidus (2n =

Comparative water balance in two species of Liomys (Rodentia: Heteromyidae)
Comparative Biochemistry and Physiology Part A: Physiology, 1978Abstract 1. 1. Water metabolism in Liomys irroratus and L. pictus was studied by measuring water loss and gain by several routes. 2. 2. Urine concentrations and fecal water contents were similar in the two species; L. pictus experiences significantly higher evaporative water loss than does L. irroratus . 3. 3.

Nematofauna of Rodents of the Families Heteromyidae and Cricetidae from the Mexican Plateau
Journal of Parasitology, 2017As a part of an ongoing project to inventory the helminth parasites of rodents in Mexico, 85 specimens of 2 families of rodents were collected from the Mexican Plateau: Cricetidae ( Neotoma sp., Neotoma leucodon , Onychomys arenicola , Peromyscus sp., Peromyscus eremicus , and Reithrodontomys sp.) and Heteromyidae ( Chaetodipus sp., Chaetodipus ...

MORPHOLOGICAL ANALYSIS OF PEROGNATHUS FLAVUS AND P. MERRIAMI (RODENTIA: HETEROMYIDAE)
The Southwestern Naturalist, 2006Abstract Morphometric variables were analyzed for 119 specimens from 28 localities in New Mexico and Texas to determine whether they can be used to distinguish between individuals of known identity of Perognathus flavus and P. merriami. Multivariate analysis of variance suggested that morphological characters from individuals of these 2 species ...

1993
Subfamily Heteromyinae Gray, 1868. Proc. Zool. Soc. Lond., 1868:201. COMMENTS: Contains the Recent genera Heteromys and Liomys, following Wood (1935), Wahlert (1985), and Ryan (1989a). However, a review of the generic limits is warranted since biochemical data (Rogers, 1990) suggested that Heteromys as currently defined is paraphyletic relative to ...

Systematic Biology, 1986
Chromosomal, genic, and morphologic variation was examined among populations of Dipodomys agilis from southern California and Baja California, including populations previ- ously recognized as D. antiquarius, D. paralius, and D. peninsularis. Populations with a diploid chromosomal number of 62 and a fundamental number of 110 were found north of San Gor-

Auditory systems of Heteromyidae: Postnatal development of the ear of Dipodomys merriami
Journal of Morphology, 1975AbstractSerial histological sections of kangaroo rats of postnatal ages 0‐, 3‐, 7‐, 10‐, and 14‐days were prepared and studied. At birth the middle ear is mostly filled with mesenchyme and small in size, having only a small hypotympanum and a very small epitympanic recess. During the first postnatal two weeks, much of the hypertrophy found in the adult
