| a study of the circadian rhythm and pre- and postpuberty concentrations of serum prolactin in male prairie deer mice (peromyscus maniculatus bairdii). | 1979 | 499748 | |
| the existence of a puberty accelerating pheromone in the urine of the male prairie deermouse (peromyscus maniculatus bairdii). | 1978 | 719090 | |
| serum corticosterone concentrations in reproductively mature and inhibited deermice (peromyscus maniculatus bairdii). | serum corticosterone concentrations were measured to see if there was any correlation between adrenal activity and reproductive inhibition. males and females from two growing and one stable (asymptotic) population had significantly smaller reproductive organs (seminal vesicles, testes, uteri, ovaries) than controls. the weights of the adrenal glands of population mice were smaller, often significantly so, than those of controls, but the mean serum corticosterone concentrations were higher than t ... | 1977 | 850211 |
| plasma progesterone concentrations in prairie deermice (peromyscus maniculatus bairdii) from experimental laboratory populations. | body weights, ovary weights, plasma progesterone concentrations and ovarian histology were studied in females from asymptotic laboratory populations in which reproduction was inhibited and throughout the oestrous cycle of control nulliparous prairie deermice. body and ovary weights of population animals were significantly lighter and plasma progesterone concentrations were not significantly different from those of the control females. the control females exhibited cyclic changes in plasma proges ... | 1975 | 1123810 |
| the effects of differential prenatal and postnatal social enviroments on sexual maturation of young prairie deermice (peromyscus maniculatus bairdii). | we compared the influence of different social enviroments on sexual maturation of young prairie deermice. between 12 and 48 hr after parturition, one-half of a litter from a population was exchanged with one-half of a litter from a bisexual pair. in each situation the remaining half-litter served as controls for the exchange procedure. the testes and vesicular weights of population-reared males were significantly larger than those of males reared by bisexual pairs, irrespective of prenatal envir ... | 1975 | 1163849 |
| the effects of feeding triiodothyronine on reproductively inhibited prairie deermice (peromyscus maniculatus bairdii) from laboratory populations. | 1. two reproductively inhibited populations were given 250 ng triiodothyronine (t3) per gram of food for 35 days to elevate the reduced serum thyroid hormone concentration previously demonstrated in reproductively inhibited animals and to determine if the treatment would promote recovery. 2. per capita food intake was significantly increased but per cent body fat tended to decrease and body weight did not significantly increase during t3 treatment. 3. mean testis and seminal vesicle weights of t ... | 1992 | 1354582 |
| reproductive development in male deer mice exposed to aggressive behavior. | male deer mice (peromyscus maniculatus bairdii) were reared in a long photoperiod and housed individually from 3 weeks of age until they were killed 2, 4, or 6 weeks later. males that were exposed to aggressive females for 2 min, three times per week, were of normal body weight and healthy, but had smaller reproductive organs than did males exposed to a control treatment. reproductive development in male deer mice is responsive to at least two classes of social stimuli: pheromones and aggressive ... | 1985 | 4039275 |

| atropine esterase status of laboratory mice. | fifty eight inbred strains of laboratory mice and two species of wild mice [mus castaneus (inbred) and peromyscus maniculatus bairdii (closed colony)] were tested for the presence of atropine esterase by the microhematocrit tube test of tucker and beattie. the results show clearly that laboratory mice do not have significant levels of atropine esterase as determined either by the microhematocrit tube test or by the agar plate test, and therefore that under these conditions atropine esterase is n ... | 1984 | 6482377 |
| photosensitive stages in pubertal development of male deer mice (peromyscus maniculatus). | male deer mice (peromyscus maniculatus bairdii) were exposed to a long (15l:9d) or short (6l:18d) photoperiod during four stages of development. at 6 weeks of postnatal age degree of pubertal development was determined by measurement of testis and seminal vesicle weights and area of the androgen-dependent sebaceous gland. continuous exposure to a short photoperiod beginning before conception (i.e. mother kept in short days), at conception, or at birth markedly retarded pubertal development. init ... | 1984 | 6512755 |
| effect of transitional photoperiods on testicular development and puberty in male deer mice (peromyscus maniculatus). | in a series of five experiments, young male deer mice (peromyscus maniculatus bairdii) were exposed to photoperiods ranging in length from 3 to 19 h per 24-h period, as well as to constant light and constant darkness. reproductive organ growth as measured at 6 weeks of age was inhibited by less than or equal to 11.5 h of light. in males receiving 11.5-19 h of light, there was a quantitative increase in reproductive organ size as a function of photoperiod. rather than a 'critical' photoperiod par ... | 1984 | 6512756 |
| influence of melatonin on pubertal development in male deer mice (peromyscus maniculatus). | the role of melatonin in pubertal development was assessed in male deer mice (peromyscus maniculatus bairdii) exposed to photoperiodic and social stimuli. exogenous melatonin retarded puberty in males reared in a long photoperiod, but was without effect in males reared in short days. melatonin did not retard pubertal development induced by exposure of short-day males to an adult female. these results suggest that pineal melatonin mediates photoperiodic, but not social, control of pubertal develo ... | 1984 | 6512757 |
| development and characterization of a homologous radioimmunoassay for deer mouse (peromyscus maniculatus bairdii) prolactin. | a highly specific and sensitive homologous radioimmunoassay has been developed for the secreted form of prolactin from the deer mouse peromyscus maniculatus bairdii. peromyscus serum and pituitary homogenates displayed parallel dilution response curves, and no cross reaction was seen with either mouse prolactin, mouse growth hormone or rat prolactin. the assay was sensitive to 25 picograms per tube and the intra- and inter-assay coefficients of variation were 5 and 3.6%, respectively. in additio ... | 1983 | 6645802 |
| isolation, purification, and characterization of deer mouse (peromyscus maniculatus bairdii) prolactin. | prolactin (prl) secreted by peromyscus maniculatus bairdii anterior pituitaries was purified by gel filtration on sephadex g-100 and ion-exchange chromatography on deae-cellulose. peromyscus prl (pmprl) eluted from sephadex g-100 with an elution-to-void volume ratio of 1.9 and at a salt concentration of 100 mm nacl on deae-cellulose. electrophoretic homogeneity of the hormone was demonstrated in several gel systems. on 7 1/2% alkaline polyacrylamide gels, pmprl migrated with an rf of 0.65. the m ... | 1983 | 6847207 |
| photoperiodic stimulation of pubertal development in male deer mice: involvement of the circadian system. | pubertal development in prairie deer mice (peromyscus maniculatus bairdii) is accelerated by exposure of juveniles to a long-day photoperiod, and, conversely, retarded by exposure to short days. the purpose of the present study was to evaluate the possible involvement of the circadian system in the photoperiodic regulation of puberty. weanling males, previously housed on a short-day light cycle of 6l:18d, were subjected to a "resonance" protocol in which they received one of the following light ... | 1983 | 6850042 |
| influence of photoperiod and social environment on sexual maturation in female deer mice (peromyscus maniculatus bairdii). | female deer mice (peromyscus maniculatus) were reared on either a long photoperiod (15:9 hr light/dark) or on short days (8:16 hr light/dark) from birth. beginning at weaning, females were housed with an adult male, with an adult female, or in social isolation. in the first experiment, vaginas opened more slowly in females on short days than in those on long days. vaginal introitus was also retarded in females reared with an adult female in comparison with females reared in isolation. when exami ... | 1983 | 6872508 |
| aggressive behaviour of female prairie deer mice in laboratory populations. | prairie deer mice (peromyscus maniculatus bairdii), living in asymptotic laboratory populations established two years earlier, were observed for agonistic responses to conspecific intruders. in the first experiment, intruders of six age-sex classes were placed into 10 of the populations for 10 min. the sex of the intruder did not influence the behaviour of the residents, but juveniles elicited more regression than did adults. a second experiment revealed that female residents were responsible fo ... | 1980 | 7194609 |

| a study of hetero-specific sperm-egg interactions in the rat, mouse, and deer mouse using in vitro fertilization and sperm injection. | hetero-specific fertilization of zone-free eggs is used in these experiments as a tool to analyze the barriers to hybridization and to gain insight into the mechanisms of normal fertilization. when the zonae of rat eggs, which are a barrier to hetero-specific fertilization, are removed with pronase, the eggs can be fertilized by mouse sperm and the zygotes start to develop normally. a rat egg fertilized with mouse sperm completes meiosis and forms both male and female pronuclei. chromosomes from ... | 1980 | 7420048 |

| phenotypic plasticity in skull and dental morphology in the prairie deer mouse (peromyscus maniculatus bairdii). | morphologists and systematists have long suspected that dietary consistency can affect skull and dental form in mammals. we examined plasticity of skull shape and tooth morphology in prairie deer mice (peromyscus maniculatus bairdii) by feeding mice diets that differed in consistency but not nutritional quality. shape differences were analyzed qualitatively and quantitatively, using both landmark-based morphometrics and traditional distance measurements. mice fed a gruel made of laboratory chow ... | 1996 | 8755340 |
| the effects of photoperiod and food intake on reproductive development in male deer mice (peromyscus maniculatus). | seasonal breeding is a tactic that has evolved in rodents that limits reproduction to specific times of the year to increase reproductive success. in order to time breeding accurately, many animals respond to changes in daily photoperiod. short day lengths inhibit breeding in many nontropical rodent species. restricted food availability can also inhibit reproductive function among some individuals in these so-called "photoperiodic" populations. rodents born at the end of the breeding season typi ... | 1997 | 9333185 |
| morphological and physiological responses to altitude in deer mice peromyscus maniculatus. | individuals within a species, living across a wide range of habitats, often display a great deal of phenotypic plasticity for organ mass and function. we investigated the extent to which changes in organ mass are variable, corresponding to environmental demand, across an altitudinal gradient. are there changes in the mass of oxygen delivery organs (heart and lungs) and other central processing organs (gut, liver, kidney) associated with an increased sustainable metabolic rate that results from d ... | 2006 | 10521329 |
| oxygen consumption and carbon dioxide production in male prairie deermice (peromyscus maniculatus bairdii) in different reproductive conditions and group densities. | natural and laboratory populations of peromyscus exhibit a profound but reversible reproductive inhibition related to population density. our earlier studies described the endocrine physiology of inhibited animals which resembles a condition of delayed puberty, but they did not reveal a primary mechanism for the induction and maintenance of the inhibition. these studies indicated that reproductive inhibition could be associated with an overall change in general metabolism. to test this hypothesi ... | 1998 | 11253796 |
| thyroxine levels in agouti and non-agouti deer mice (peromyscus maniculatus). | total thyroxine was assessed by radioimmunoassay for 58 female deer mice of two subspecies (peromyscus maniculatus bairdii and p. m. gracilis) and two color morphs (agouti and non-agouti). p. m. bairdii of both color-morphs had significantly higher mean thyroxine levels than p. m. gracilis. non-agouti deer mice of both subspecies had significantly higher mean thyroxine levels than agouti deer mice. this is the first report of thyroid hormone differences associated with the non-agouti allele. | 2001 | 11544074 |
| dissociation between spontaneously emitted and apomorphine-induced stereotypy in peromyscus maniculatus bairdii. | stereotyped behavior is repetitive, topographically invariant motor activity that lacks an obvious function. we have previously characterized the spontaneous and persistent stereotypies that occur in deer mice housed in standard laboratory cages. providing these animals with enriched environments markedly reduces their vulnerability to develop stereotypic behavioral repertoires, thus enabling us to generate behaviorally distinct (stereotypic and nonstereotypic) mice of the same species. as stere ... | 2002 | 11897261 |
| age of weaning in two subspecies of deer mice. | weaning age in deer mice is defined as the age at which the young mice maintain or gain weight during a 24-hour period of isolation; mice younger than weaning age lose weight. two subspecies of deer mice differed in weaning age; the age for peromyscus maniculatus bairdii was 18 days; for p. m. gracilis, 24 days. age and food consumption were better predictors of the weaning condition, as defined in terms of weight change with isolation, than body weight. | 1963 | 14032839 |
| development of a deer mouse whole-genome radiation hybrid panel and comparative mapping of mus chromosome 11 loci. | a 5000-rad whole-genome radiation hybrid cell panel (bw5000) was developed for mapping the deer mouse (peromyscus maniculatus bairdii) genome. the panel consists of 103 cell lines and has an estimated marker retention frequency of 63.9% (range, 28%-88%) based on pcr typing of 30 type i (coding gene) and 25 type ii (microsatellite) markers. using the composite mus map, type i markers were selected from six mus chromosomes, 22 of which are on mus chr 11. fifteen of the mus chr 11 markers were simu ... | 2006 | 16416089 |
| stereotypic behaviour in the deer mouse: pharmacological validation and relevance for obsessive compulsive disorder. | stereotypy is an important manifestation of obsessive compulsive disorder (ocd). ocd involves disturbed serotonin and dopamine pathways, and demonstrates a selective response to serotonin reuptake inhibitors (sri), with limited to no response to noradrenaline reuptake inhibitors (nri). deer mice (peromyscus maniculatus bairdii) engage in various spontaneous stereotypic behaviours, including somersaulting, jumping and pattern running, and has to date not been explored for possible relevance for o ... | 2008 | 17888556 |
| old mice, young islands and competing biogeographical hypotheses. | naturally occurring variation within a small rodent species native to the southeastern usa, peromyscus polionotus, has interested biologists for nearly a century. this species has contributed significantly to our understanding of geographical variation and has often been presented as an example of adaptive evolution. much of the interest in this organism has been predicated on assumptions that the species is relatively young (<300 000 bp) and that coastal populations have a very recent history ( ... | 2007 | 17956552 |
| adaptive genetic variation, stress and glucose regulation. | elevated glucose levels in the presence of insulin are indicative of type 2 diabetes and the more inclusive metabolic syndrome. alleles conferring susceptibility to these and other common conditions may be adaptations to past environments. it is possible that other mammals exhibiting environmental diversity harbor similar variants; therefore, we assessed glucose regulation in two species of deer mice (peromyscus), a diverse endemic north american group. the prairie deer mouse, p. maniculatus bai ... | 2008 | 19093033 |
| sex and dose-dependent effects of developmental exposure to bisphenol a on anxiety and spatial learning in deer mice (peromyscus maniculatus bairdii) offspring. | bisphenol a (bpa) is a widely produced, endocrine disrupting compound that is pervasive in the environment. data suggest that developmental exposure to bpa during sexual differentiation of the brain leads to later behavioral consequences in offspring. outbred deer mice (peromyscus maniculatus bairdii) are an excellent animal model for such studies as they exhibit well-defined sex- and steroid-dependent behaviors. here, dams during gestation and lactation were fed with a phytoestrogen-free contro ... | 2013 | 23051835 |
| a genetic map of peromyscus with chromosomal assignment of linkage groups (a peromyscus genetic map). | the rodent genus peromyscus is the most numerous and species-rich mammalian group in north america. the naturally occurring diversity within this genus allows opportunities to investigate the genetic basis of adaptation, monogamy, behavioral and physiological phenotypes, growth control, genomic imprinting, and disease processes. increased genomic resources including a high quality genetic map are needed to capitalize on these opportunities. we produced interspecific hybrids between the prairie d ... | 2014 | 24445420 |
| rapid morphological change in the masticatory structures of an important ecosystem service provider. | humans have altered the biotic and abiotic environmental conditions of most organisms. in some cases, such as intensive agriculture, an organism's entire ecosystem is converted to novel conditions. thus, it is striking that some species continue to thrive under such conditions. the prairie deer mouse (peromyscus maniculatus bairdii) is an example of such an organism, and so we sought to understand what role evolutionary adaptation played in the success of this species, with particular interest i ... | 2015 | 26061880 |
| a novel satellite dna sequence in the peromyscus genome (pmsat): evolution via copy number fluctuation. | satellite dnas (satdna) are tandemly arrayed repeated sequences largely present in eukaryotic genomes, which play important roles in genome evolution and function, and therefore, their analysis is vital. here, we describe the isolation of a novel satellite dna family (pmsat) from the rodent peromyscus eremicus (cricetidae, rodentia), which is located in pericentromeric regions and exhibits a typical satellite dna genome organization. orthologous pmsat sequences were isolated and characterized fr ... | 2015 | 26103000 |

| interspecific comparison of hantavirus prevalence in peromyscus populations from a fragmented agro-ecosystem in indiana, usa. | comparatively little is known about hantavirus prevalence within rodent populations from the midwestern us, where two species of native mice, the prairie deer mouse ( peromyscus maniculatus bairdii) and the white-footed mouse ( peromyscus leucopus noveboracensis), are dominant members of rodent communities. we sampled both species in central indiana and tested individuals for presence of hantavirus antibodies to determine whether seroprevalence (percent of individuals with antibodies reactive to ... | 2018 | 28977768 |
| peromyscus maniculatus bairdii as a naturalistic mammalian model of obsessive-compulsive disorder: current status and future challenges. | obsessive-compulsive disorder (ocd) is a prevalent and debilitating condition, characterized by intrusive thoughts and repetitive behavior. animal models of ocd arguably have the potential to contribute to our understanding of the condition. deer mice (permomyscus maniculatus bairdii) are characterized by stereotypic behavior which is reminiscent of ocd symptomology, and which may serve as a naturalistic animal model of this disorder. moreover, a range of deer mouse repetitive behaviors may be r ... | 2017 | 29214602 |
