| saltbush leaves: excision of hypersaline tissue by a kangaroo rat. | dipodomys microps climbs into shrubs and harvests leaves of the halophyte atriplex confertifolia throughout the year. the epidermal vesicles of these leaves are high in electrolyte concentration, but the specialized photosynthetic parenchyma which is arranged concentrically about the vascular bundles is low in electrolytes and high in starch. the lower incisors of d. microps are broad, flattened anteriorly, and chisel-shaped (unlike those of other kangaroo rats, which are rounded and awl-shaped) ... | 1972 | 17741983 |
| rainfall and fluctuating plant populations in relation to distributions and numbers of desert rodents in southern nevada. | fluctuations in rainfall and size of desert rodent and plant populations for each of five consecutive years were documented on 68 sites in mojave, great basin, and transition desert communities of central-southern nevada. post-reproduction rodent densities in the summer usually followed the seasonal patterns of winter annual success the previous spring, in turn directly related to the success of germination the preceding autumn.in the "dipodomys merriami environment", at the lower elevations wit ... | 1976 | 28308851 |
| derivation of soil-screening thresholds to protect the chisel-toothed kangaroo rat from uranium mine waste in northern arizona. | chemical data from soil and weathered waste material samples collected from five uranium mines north of the grand canyon (three reclaimed, one mined but not reclaimed, and one never mined) were used in a screening-level risk analysis for the arizona chisel-toothed kangaroo rat (dipodomys microps leucotis); risks from radiation exposure were not evaluated. dietary toxicity reference values were used to estimate soil-screening thresholds presenting risk to kangaroo rats. sensitivity analyses indic ... | 2013 | 23604138 |
| reingestion of feces in rodents and its daily rhythmicity. | the ingestion of feces is widespread among rodent species and is an extensively employed component of the repertoire of feeding behaviors in some species. coprophagy is thus a significant consideration in the nutrition and dietary ecology of many rodents. as certain fecal pellets pass from the anus, they are taken up directly into the mouth, chewed, and swallowed. the nocturnally active herbivorous kangaroo rat dipodomys microps ingests about 1/4 of the feces it produces daily and the daily patt ... | 1979 | 28310297 |
| adaptations for leaf eating in the great basin kangaroo rat, dipodomys microps. | dipodomys microps forages in saltbush (atriplex confertifolia), gathering the leaves into its external check pouches and returning them to the burrow to be cached or eaten. the leaves are available throughout the year and contain 50-80% water. d. microps can survive on these leaves in the laboratory without other food or water, but it is unusual among kangaroo rats in that it quickly succumbs when placed on a diet of air-dried seeds without water or succulent plant material. its mean urine conce ... | 1973 | 28308238 |
