Hereditary Cataracts in Deer Mice (Peromyscus Maniculatus)
American Journal of Ophthalmology, 1975A new type of hereditary cataract was predicted in the deer mouse (Peromyscus maniculatus) by the presence of syndactyly of the hind feet. Early morphologic changes were found in the equatorial cells that differentiated into new lens fibers. Later swelling at the anterior and posterior poles of these cells produced lens opacities.

Immunosuppression in Deer Mice with Experimentally Induced Trypanosomiasis
American Journal of Veterinary Research, 1977SUMMARY Light and electron microscopic examinations of deer mice (Peromyscus maniculatus) chronically infected with Trypanosoma equiperdum revealed hyperplasia of germinal center lymphocytes (germanocytes) in the lymph follicles of spleen and lymph nodes and infiltration of the splenic red pulp cords and nodal medullary cords with plasma cells ...

Season affects tolerance of cohabitation by deer mice
Physiology & Behavior, 1993We measured the resting metabolic rates of Peromyscus maniculatus for 7 days before and 7 days following forced pairing in order to determine whether seasonal light cycles influenced the rates of behavioral and metabolic habituation of deer mice to cohabitation.

Genetic selection for reproductive photoresponsiveness in deer mice
Nature, 1986Seasonal breeding is common in mammals, particularly in habitats outside the tropics. Climate and availability of food are the ultimate factors that usually dictate the optimal time of year for a mammal to breed; however, day length (photoperiod) often serves as the proximal cue to signal the onset or cessation of seasonal reproduction.

Photoperiodic adjustment of thermal conductance in deer mice
Comparative Biochemistry and Physiology Part A: Physiology, 1986Seasonal changes in metabolic rate can be induced in mice held in thermal neutral (26-29 degrees C) ambient temperatures. The metabolic effect of winter photoperiod is a lower metabolic rate without compromise to metabolic reserve. Manipulations of photoperiod or melatonin backgrounds adjust the thermoregulatory setting for core temperature level and ...

Further Studies on Parasitic Obesity in Mice, Deer Mice, and Hamsters
The Journal of Parasitology, 1965Accelerated weight gain caused by infection with spargana of Spirometra mansonoides occurs in male mice as well as females, and in older mice approximating 40 g starting weight, as well as in younger animals. Below a starting weight of 10 g the effect is greatly reduced and delayed if seven spargana per mouse are used.

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.

Standardized karyotype of deer mice, Peromyscus (Rodentia)
Cytogenetic and Genome Research, 1977£A standard G-band karyotype is proposed for the genus <i>Peromyscus</i>. G-banded chromosomes of <i>Peromyscus boylii glasselli</i> (NF = 56), numbered and arranged according to euchromatic lengths, serve as the standard. It is suggested that rearrangements of the standard pattern which occur in other species of <i> ...
