in vitro fertilization of two species of deer mouse eggs by homologous or heterologous sperm and penetration of laboratory mouse eggs by deer mouse sperm.	newly ovulated eggs from immature deer mice (peromyscus maniculatus and p. polionotus) and mature laboratory mice (mus musculus) treated with pmsg and hcg were inseminated in vitro with spermatozoa recovered from the cauda epididymidis of mature males. the time required for capacitation of deer mouse sperm in culture was estimated to be about two to five hours based on the dispersal of sperm agglutination and increase of sperm motility. the rate of sperm penetration through the zona pellucida of ...	1979	572865
effects of bot fly (cuterebra) parasitism on activity patterns of peromyscus maniculatus in the laboratory.	peromyscus maniculatus subjected to bot fly (cuterebra) parasitism in the laboratory showed significant changes in amount and temporal distribution of several activity patterns. strenuous activities, such as running in an exercise wheel or stereotypic somersaulting, declined while less strenuous activities associated with maintenance behaviors increased. diurnal response to handling and disturbance declined significantly in infected mice. the temporal distribution of nocturnal activity was alter ...	1978	564978
space utilization of peromyscus: social and spatial factors.	space utilization of peromyscus maniculatus bairdi and p. leucopus noveboracensis was studied in laboratory enclosures. after 1 week, individuals were given access to twice as much space for an additional week. the new rea was either vacant or was occupied by a similarly experienced conspecific of the same or opposite sex. patterns of space utilization and reaction to the doubling of space were species specific. each species displayed specific patterns of social behaviour and only p. maniculatus ...	1977	560813
a study of the circadian rhythm and pre- and postpuberty concentrations of serum prolactin in male prairie deer mice (peromyscus maniculatus bairdii).		1979	499748
reproductive failure and maternal-fetal relationship in a peromyscus species cross.	mating, fertilization, implantation, prenatal mortality, fetal and placental size, and placental ultrastructure were studied in intraspecific and interspecific crosses involving peromyscus maniculatus and p. polionotus. failure to mate was a major factor in interspecific crosses and was much more pronounced in crosses between p. polionotus females and p. maniculatus males than in the reciprocal cross. failure of implantation following mating, however, was more pronounced in crosses between p. ma ...	1979	490135
cataract--webbed peromyscus. i. genetics of cataract in p. maniculatus.	cataract--webbed (cw) in the deer mouse (peromyscus maniculatus) is a recessive mutant that is manifested by syndactyly (involving soft tissues) and eye defects including cataract. within cw/cw mice, the age at which cataract first appears is genetically controlled. evidence for the activity of genetic modifiers is the early appearance of cataracts in the offspring of parents that developed cataracts at early ages.	1979	469220
rodent housing units for field studies.	rodent housing and nesting units were constructed from acrylic and provided with concrete tops. these hexagonal units, placed in a wooded field, were inhabited by deer mice (peromyscus maniculatus). the use of the field housing units provided an effective method for observing free-ranging wild rodents.	1979	459426
experimental meningoencephalitis in trypanosoma brucei infection of deer mice (peromyscus maniculatus). a light, immunofluorescent, and electron microscopic study.		1977	331839
immunosuppression in deer mice with experimentally induced trypanosomiasis.	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. proliferation and infiltration of plasma cells caused disruption of the b- and t-lymphocyte areas in these organs. stimulation of splenic lymphocytes in vitro by ...	1977	327872

a soluble immunosuppressor substance in spleen in deer mice infected with trypanosoma brucei.	a soluble substance that blocks b-cell response was extracted from spleen of deer mice (peromyscus maniculatus) chronically infected with trypanosoma brucei. immunosuppressor activity of this substance was demonstrated by plaque-forming cell assays of spleen cells from swiss/webster mice inoculated with sheep red blood cells and simultaneously given the suppressor substance, and of spleen cell cultures treated with sheep red blood cells and suppressor substance. studies by light and electron mic ...	1979	316660
physiological consequences of experimentally altering the population structure of peromyscus maniculatus in the field.		1975	237700
hereditary cataracts in deer mice (peromyscus maniculatus).	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. anterior and posterior subcapsular cataracts progressed to a hypermature shrunken lens.	1975	169695
rodent models of the human isoniazid-acetylator polymorphism.	inbred strains and subpopulations of rats, laboratory mice, and deer mice were examined for individual variation in the ability to metabolize several arylamines (p-aminobenzoic acid, sulfamethazine, aniline, alpha-naphthylamine, and aminofluorene) by n-acetylation. individual differences within species were found to be dependent upon the tissue source of n-acetyltransferase activity and the acetyl acceptor employed. long-evans rats possessed about 2-fold more p-aminobenzoic acid n-acetyltransfer ...	1979	40765

preferences by deer mice for solutions of sugars, salts, and acids in richter-type drinking tests.	deer mice (peromyscus maniculatus) were tested for taste preferences in 48-hour, richter-type drinking tests (sapid solution versus distilled water). the ss, which were seven male and seven female wild adults, were individually housed within an environmental chamber. test solutions were concentrations of five sugars and three salts (.005 m to 1.0 m) and of two acids (4.0 ph to 1.5 ph). the molar range was too limited to identify the most preferred concentration of glucose, but peak preferences f ...	1978	26730
