Genetic variation of amylases in deer mice
Journal of Heredity, 1977The inheritance of salivary amylase variants in the deer mouse, Peromyscus maniculatus, is controlled by codominant alleles, Amy-1a, Amy-1b, and Amy-1c, at a single autosomal locus. Pancreatic amylases were invariant and unaffected by salivary amylase genotypes.

Seasonal acclimation of prairie deer mice
International Journal of Biometeorology, 1993Prairie deer mice responded to long nights by reducing their metabolic rates, core temperatures, thermal conductances and incremental metabolic responses to cold stimulus, while increasing their capacities for nonshivering thermogenesis. Some winter animals spontaneously entered daily torpor in the mornings and thereby further reduced their metabolic ...

Adrenalectomy and Coat Color in Deer Mice
Science, 1966Adrenalectomy in prairie deer mice is followed by a profound darkening of the fur which occurs within 1 to 3 months. The phenomenon is most noticeable on the normally unpigmented ventral surfaces which turn dark gray or black. A possible mechanism for such hyperpigmentation would involve increased release of melanocyte-stimulating hormones.

TEMPERATURE SELECTION IN DEER MICE
Canadian Journal of Zoology, 1953The behavior of individuals of the genus Peromyscus has been studied in an 8 ft. aluminum tube in which a gradient of temperature could be established. When the tube was at a uniform temperature the mice were found most commonly at the two ends. With the gradient set up providing a range of temperatures from 6° to 50 °C.

Genetic divergence of insular populations of deer mice
Biochemical Genetics, 1976Electrophoretic variants at 28 genetic loci were analyzed in subspecies of Peromyscus maniculatus endemic to the Channel Islands of the California coast. The genetic variability within insular populations was calculated. These deer mice have relatively high levels of polymorphism for insular populations. The mean heterozygosity per individual varies in

MODES OF ECTOPARASITE REINFESTATIONS OF DEER MICE (Peromyscus maniculatus)
Journal of Wildlife Diseases, 1980Modes of ectoparasite reinfestations were studied on ectoparasite-free deer mice (Peromyscus maniculatus) returned to their natural habitat on the Tule Lake National Wildlife Refuge, Siskiyou County, California, during the summer of 1977. The age of the host made no significant difference in the mode of reinfestation of lice, fleas, or mites.

Bioenergetic benefits of huddling by deer mice (Peromyscus maniculatus)
Comparative Biochemistry and Physiology Part A: Physiology, 1986Both short photoperiod and communal social living conserve metabolic energy by deer mice held in thermal neutral ambient temperatures. Initial socialization was energetically more costly than solitary living, but huddling behaviors reduced thermal conductance and mass specific metabolic rate by 30% within 5 days.

Low P50 in deer mice native to high altitude
Journal of Applied Physiology, 1985Whereas it is widely believed that animals native to high altitude show lower O2 partial pressures at 50% hemoglobin saturation (P50) than do related animals native to low altitude, that “fact” has not been well documented. Consequently, P50 at pH 7.4, PCO2(7.4), the CO2 Bohr effect, and the buffer slope (delta log PCO2/delta pH) were determined via ...
