similarly, but differ from earlier results in that the ages of the mice for this population were known, and therefore the organ weights can be plotted against age rather than weight. A suppression of growth in all mice but those from the first litters is clearly shown. These and, especially, originally introduced animals were dominant in the population. Note the greater preputial weight of males more than 95 days old compared to their controls, whereas the seminal vesicles were smaller in all…

Is there a difference between testosterone contents in two populations of the Black Eared Mouse, living under similar conditions but with differences in population patterns?

T showed no differences between the two popula-tions, since both had the same seasonal pattern for the androgen, throughout four years of study, with a maximum in the summer, as would be expected in this temperate species whose reproductive optimum occurs at that time of the year.

Physiological and Pathological Correlates of Population Density

A large body of evidence has accumulated over the past decade which supports the hypothesis that endocrine responses to increasing density, barring outside intervention, can regulate and limit population growth, largely by progressively decreasing natality and increasing mortality as population size increases.

Population Cycles in Small Rodents

It is concluded that population fluctuations in Microtus in southern Indiana are produced by a syndrome of changes in birth and death rates similar to that found in other species of voles and lemmings, and the prevention of dispersal changes the quality of the populations in the enclosures in comparison to those outside the fence.

Patterns of Disease, Controlled Populations, and Experimental Design

Experiences of the Philadelphia Zoologrical Garden suggest that studies of spontaneous disease, as it may develop in any group or population, must consider all environmental factors, and that malnutrition, not "constitution," had determined to a very large degree the earlier patterns of disease.

Using ecology to inform physiology studies: implications of high population density in the laboratory.

Evidence from ecology that density influences glucocorticoid levels, immune function, and body condition is presented across three taxa: mammals, birds, and fish with the intention of stimulating discussion and increasing consideration of population density in physiology studies.

The natural regulation of buffalo populations in East Africa: III. Population trends and mortality*

Analysis of population data obtained from censuses and estimates of fertility and recruitment for the years 1965-1972 suggests that disease and predation play an essential role by hastening the population's response to changes in the food supply, and hence dampening oscillations that might develop in population and resource.

Relationship of activity and aggression to density in two confined populations of house mice (Mus musculus).

In view of the data gathered from the populations it was concluded that aggression did not directly affect infant mortality in either of the populations.

Serum corticosterone concentrations in reproductively mature and inhibited deermice (Peromyscus maniculatus bairdii).

The data suggest that adrenal function may be associated with the reproductively inhibited condition, but not in a direct or dose-response fashion and that Adrenal hyperfunction in this species may not be reflected by adrenal hypertrophy.

The Relation Between Level of Population and Pregnancy of Norway Rats

The preliminary summary (Davis 1949) indicated that a subasymptotic population has a higher pregnancy rate than has an asymptotic one, and an increasing population had a great increment of pregnancy in the breeding season in contrast to the other populations.

It is suggested that the strife between the members of each population was limiting their growth, but that this restraint was more severe in the larger than the smaller group.

The Characteristics of Rat Populations

The characteristics of a particular group of animals (a population) is the subject of this review, which is concerned with populations of wild rats and the species Rattus norvegicus is the best known of more than 400 named forms in the genus Rattus.

Daily observations of the social behavior of more than 300 male and approximately 150 female white mice, arranged in 85 groups of various sizes and composition, yielded the following results: 1.

The relationship of the mouse adrenal cortex to the pituitary.

The course of events in the mouse adrenal cortex after hypophysectomy has been dealt with (Jones, 1949; 1950). It seems that the zona glomerulosa is independent of the pituitary in so far as it may

The introduction of aliens into an existing population of mammals may be followed by unexpected effects that relate to social structure and population composition. These effects were studied by

It was concluded that an increase in splenic weight was associated with grouping and this suggests suppression of gonadal function and gonadotrophin secretion in grouped nulliparous females.

A factor influencing the significance of radiation mortality experiments.

Cage effect can probably be avoided by caging each mouse individually, and this was found not to alter radiation sequellae materially, and it was shown that valid mortality comparisons can be made with multiple animal caging if each mouse is housed separately.

This animal has further advantages as a subject for experimentation in that it breeds rapidly and nearly continuously throughout the year, is relatively sedentary in its habits, and tolerates high population densities.
