| fractionation and characterization of satellite dnas of the kangaroo rat (dipodomys ordii). | nuclear dna from liver cells of the kangaroo rat species dipodomysordii was fractionated and characterized with the aid of buoyant density gradients in neutral and alkaline cscl and in ag(+)-cs(2)so(4). more than one-half of the dna was present in three density satellites, a greater proportion than in any other species yet reported; the purified satellite dnas were denser than principal dna. all satellite fractions revealed sharp isopycnic bands and narrow denaturation profiles. two had identica ... | 1974 | 10793740 |
| perturbation analysis of competition and overlap in habitat utilization between dipodomys ordii and dipodomys merriami. | the populations of two coexisting species of dipodomys (heteromyidae, rodentia) were manipulated on 10, large, unenclosed, trapping grids. these manipulations revealed that, although many kangaroo rats are established residents in an area, a large number are transient individuals who quickly occupy vacated habitats. on plots from which residents had been removed, transients settled at rates of up to 5% of carrying capacity per day. these immigrants were invariably of the same species that was re ... | 1975 | 28308827 |
| chromosomes of a cell line of dipodomys panamintinus (kangaroo rat). a banding and autoradiographic study. | the chromosomes of an established cell line of dipodomys panamintinus have been characterised in terms of their c, g and q banding patterns, and the distributions of silver grains in autoradiographs of chromosomes labelled in early or late s phase. no relationship could be established between c, g or q banding regions of chromosomes and a particular s phase time of replication of the dna in these banded regions. the implication of this result to the concept of heterochromatin is discussed. | 1975 | 49259 |
| cns regulation of metabolic rate in the kangaroo rat dipodomys ingens. | water-perfused thermodes were chronically implanted around the preoptic nuclei and hypothalamus (poh) of kangaroo rats (dipodomys ingens). responses in rate of metabolic heat production to manipulations of poh temperature (thy) were measured in unanesthetized, unrestrained animals at ambient temperatures of 10, 20, 25, and 30 degreec. the threshold thy and the proportionally constant (alpha) for this response consistently decreased as ambient temperature increased, but alpha was not significan ... | 1975 | 168786 |
| auditory systems of heteromyidae: postnatal development of the ear of dipodomys merriami. | serial 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 middle ear develops. because an entotympanic element is nev er formed, the previously called entotympanic chamber is here renamed the hypotympanum. the e ... | 1975 | 1142445 |
| functional characteristics of superior olivary neurons to binaural stimuli. | this investigation was undertaken to study the timing properties of low-frequency binaural neurons located in the medulla of kangaroo rat (dipodomys spectabilis). the results show that the response variables, vector strength (vs) and discharge rate (dr), are not necessarily related responses; each may be conveying a different parameter of acoustic stimuli. the results also lead to the conclusion that binaural low-frequency neurons, whether they are excitatory-excitatory (ee) or excitatory-inhibi ... | 1975 | 1177003 |
| projections of the trapezoid body and the superior olivary complex of the kangaroo rat (dipodomys merriami). | glass micropipettes filled with 2 m sodium cyanide were used to physiologically locate and iontophoretically damage the nucleus of the trapezoid body (ntb), the medial superior olive (mso), and the lateral superior olive (lso). mechanical lesions were made in the trapezoid body as it leaves the cochlear nuclei. after a 3- to 10-day survival time the projections and terminal degeneration were traced with the fink-heimer and nauta-gygax stains. the ventral cochlear nucleus (vcn) projects via the t ... | 1975 | 1192176 |
| the fine structure of the trophospongial layer of the kangaroo rat placenta. | the trophospongial layer of the near-term kangaroo rat placenta was examined in the electron microscope. two ultrastructurally different cellular zones were distinguishable - an inner zone adjacent to the labyrinth and a basal zone located mesometrial to the inner zone. inner zone cells contained a well developed granular er and golgi apparatus as well as polymorphous membrane-limited granules. the cells also contained modest amounts of glycogen and lipid droplets. basal zone cells were also ric ... | 1975 | 1200411 |
| intrinsic innervation of the urinary bladder of kangaroo and albino rats. | a comparative study of the intrinsic innervation in desert rodents (kangaroo rats) and others (albino rats) was carried out in an attempt to understand the functional anatomy of the bladder in these animals which are known to sustain severe water restraint. the bladder of the albino rat was innervated by predominantly thin nerves, more numerous beaded endings and few ganglia. that of the kangaroo rat had more numerous thick nerves (pre-ganglionic), large verve trunks, and ganglia which were exte ... | 1975 | 1155000 |

| analysis of the frequency of sister chromatid exchange in different regions of chromosomes of the kangaroo rat (dipodomys ordii). | the frequency of sister chromatid exchanges (sces) has been determined for c band and non-c band regions of chromosomes of the kangaroo rat after staining with the fluorescence plus giemsa (fpg) technique. after one complete round of dna synthesis in the presence of bromodeoxyuridine (brdu) staining of the c band regions revealed simple or complex asymmetries between chromatids. after two complete rounds of dna synthesis in the presence of brdu "harlequin" chromosomes were observed. analysis of ... | 1976 | 964105 |
| investigation of the organization of mammalian chromosomes at the dna sequence level. | new developments in dna sequencing techniques permit rapid progress in the determination of both repetitious and single-copy mammalian sequences. three distinct families of highly repetitious satellite dna's from the kangaroo rat dipodomys ordii have been sequenced. with the ms satellite it was possible to show that the basic repeat sequence and its variants were arranged in a nonrandom order suggesting a hierarchy of repeats. the hs-alpha satellite from d. ordii was shown to resemble the guinea ... | 1976 | 1107072 |

| central nervous regulation of body temperature during sleep. | the relationship between hypothalamic temperature and metabolic heat production was measured during wakefulness, slow-wave sleep, and paradoxical sleep in unrestrained kangaroo rats (dipodomys). hypothalamic temperature was manipulated with chronically implanted, water-perfused thermodes while cortical electroencephalogram, electromyogram, metabolic rate, and body movement were continuously recorded. during slow-wave sleep, in comparison to wakefulness, there is a lowered threshold hypothalamic ... | 1976 | 973138 |
| an analysis of sandbathing and grooming in the kangaroo rat (dipodomys merriami). | the sandbathing and grooming behaviour of ten kangaroo rats (dipodomys merriami) were recorded on sand and woodchip substrates after periods of 0, 1, 5 and 10 days without sand. sandbathing is restricted to the sandy substrate. grooming occurs on both, but with a higher frequency on sand. increases in both grooming and sandbathing occur with increasing sand deprivation, but the temporal patterning does not change. d. merriami tends to alternate sandbathing components in contrast to other dipodom ... | 1976 | 937766 |
| fine structure of the heterochromatin of the kangaroo rat dipidomys ordii, and examination of the possible role of actin and myosin in heterochromatin condensation. | biochemical studies have suggested that some actin and myosin may be present in the nucleus. this raises the possibility that heterochromatin condensation might be the result of an actin-myosin rigour type complex. since atp dissociates actin and myosin, this possibility could be examined by determining the effect of atp on heterochromatin condensation. thin-section electron microscopy showed large amounts of condensed constitutive heterochromatin in the kidney nuclei and somewhat less in the li ... | 1976 | 823163 |
| mechanisms of chromosome banding. ix. are variations in dna base composition adequate to account for quinacrine, hoechst 33258 and daunomycin banding? | prior studies on subfractions of mouse and kangaroo rat dna have suggested that variations in base concentration within a given genome may not be great enough to account for q-banding. to examine this with another species, calf dna was subfractionated by cscl ultracentrifugation into gc-rich satellites and the main band dna was further fractionated into at-rich, intermediate and gc-rich portions. the effect of varying concentrations of these dnas on quinacrine and hoechst 33258 fluorescence was ... | 1976 | 61106 |
| the periodicity of daily activity and its seasonal changes in free-ranging and captive kangaroo rats. | populations ofdipodomys microps andd. merriami in eastern california (37°11'n. lat.) are active on the surface throughout the night and during the whole year. these two species, and the males and females within each species, show no significant differences in times of beginning or end of activity. beginning and end of nightly activity generally fall within the brighter part of the twilights, even though the total time spent on the surface by individuals is at times only an hour or two, or even l ... | 1976 | 28309330 |
