Age of Weaning in Two Subspecies of Deer Mice
Science, 1963Weaning 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

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 ...

Peromyscus (deer mice) as developmental models
WIREs Developmental Biology, 2013Deer mice (Peromyscus) are the most common native North American mammals, and exhibit great natural genetic variation. Wild‐derived stocks from a number of populations are available from the Peromyscus Genetic Stock Center (PGSC). The PGSC also houses a number of natural variants and mutants (many of which appear to differ from Mus).

Acoustic communication: Deer mice join the chorus
Current Biology, 2023A new study has identified two distinct pup vocalizations in deer mice, showing that discrete genetic loci explain the acoustic variation between these two call types and that the calls elicit different levels of maternal responsiveness.

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.

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.

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.

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.
