Communal Litters of Peromyscus maniculatus

Journal of Mammalogy, 1957
Most authors agree that a female deer mouse with a young litter does not tolerate the presence of other adults in the same nest with her young (Dice, Jour. Mamm., 10: 116–124, 1929; Svihla, Misc. Publ. Mus. Zool. Univ. Mich., 24, 1932; Blair, Jour. Mamm., 22: 378–383, 1941).

Hereditary Cataracts in Deer Mice (Peromyscus Maniculatus)

American Journal of Ophthalmology, 1975
A 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.

Hemoglobin polymorphism in the deer mouse,Peromyscus maniculatus

Biochemical Genetics, 1968
Horizontal starch gel electrophoresis reveals three hemoglobin phenotypes in natural populations of the deer mouse, Peromyscus maniculatus,from northern Arizona. Phenotypic variation is controlled by a single locus. A sample of deer mice from Michigan was monomorphic for a multiple-banded phenotype.

Genetic Composition of Fluctuating Populations of Peromyscus leucopus and Peromyscus maniculatus

Journal of Mammalogy, 1989
Populations of two species of cricetine rodents, Peromyscus leucopus and P. maniculatus , sampled during a 6-year period were analyzed by electrophoresis for genetic variability at 33 presumptive loci. Population densities fluctuated concurrently for both species during this time period.

Peromyscus maniculatus (Deer mouse)

1974
It is well-known that the chromosome morphology of this species is extremely polymorphic. Not only may they differ from subspecies to subspecies, but also from individual to individual within a population. Generally speaking, Southern subspecies possess a lower number of biarmed chromosomes whereas Northern subspecies possess a higher number of biarmed

A Population-High for Peromyscus maniculatus

Journal of Mammalogy, 1955
Irruptive populations of Peromyscus maniculatus occasionally have been reported, but generally no data on population structure are available. A very dense population was encountered in June, 1954, in the White Mountains of Mono County, California. In a period of eight days of snap trapping in Cottonwood Creek basin, 9500 ft.

Reproduction by Peromyscus maniculatus: Size and Compromise

Journal of Mammalogy, 1983
Breeding records from a laboratory colony of Peromyscus maniculatus bairdii were used to examine patterns of covariation among variables describing reproduction, size, age, parity, and survival. Litter size was strongly negatively correlated with average weights of young at birth and at weaning, but positively related to the total mass of young. Mother'
