Behavioural adaptations of desert rodents (Heteromyidae)

Animal Behaviour, 1993
Abstract 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.

Patch use by Dipodomys deserti (Rodentia: Heteromyidae): profitability, preference, and depletion dynamics

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.

Comparative water balance in two species of Liomys (Rodentia: Heteromyidae)

Comparative Biochemistry and Physiology Part A: Physiology, 1978
Abstract 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, 2017
As 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, 2006
Abstract 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 ...

Heteromyinae Gray 1868

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 ...

Chromosomal, Genic, and Morphologic Variation in the Agile Kangaroo Rat, Dipodomys Agilis (Rodentia: Heteromyidae)

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-
