Graminivory by kangaroo rats (Dipodomys spp.) was investigated as a potential mechanism for the keystone role of these rodents in the dynamics of desert grasslands. Experiments confirmed that Ord's kangaroo rats (Dipodomys ordii) cut and consumed a l

Between 1995 and 1997, grazing regimes and mesquite (Prosopis glandulosa) shrub removal were combined in a factorial arrangement to assess changes in small mammal communities on the Jornada Experimental Range in southern New Mexico. Small mammals wer

In this study, the density of banner-tailed kangaroo rat ( Dipodomys spectabilis ) mounds across a range of habitat types near Las Cruces, New Mexico was determined. Mound density varied four-fold between sites. Mound, vegetation and soil characteris

Disturbance-caused patchiness is important for development and maintenance of spatial and temporal heterogeneity in ecosystems. Mammals are important agents of biopedturbation (soil disturbance by organisms) which is a major source of patchiness in a

Two types of mesh live traps were better than Sherman traps for capturing rodents in high and low deserts, Mediterranean grassland and shrubland, and riparian woodland and scrub habitats ( P < 0.001). Mesh traps took more species and more individuals

1. 1. Data on 2, 3-diphosphoglycerate, P 50 , the Bohr Effect Factor and T B of a variety of mammalian species was summarized and two discrete clusters of species were found, a low DPG group and a high DPG group. 2. 2. The low DPG group tended to hav

1. 1. Mean body temperature of Dipodomys spectabilis acclimated to 25°C was constant at ambient temperatures from − 5 to 15°C, and was reduced in the thermoneutral zone (20–30°C). 2. 2. Lethal air temperature was 40°C. 3. 3. There was no appa

1. 1. Oxygen consumption and evaporative water loss were measured in response to burrow and control temperature, water vapor pressure and inspired CO2 concentration for Dipodomys spectabilis. 2. 2. Oxygen uptake of banner-tail kangaroo rats increased
