The Effects of Social Stress on Reproduction in a Wild Deermouse Population (Peromyscus Leucopus)
Seton (1909) stimulated wide interest in the fluctuation of population density of Arctic mammals. However, his account of suicidal migrations of lemmings was based on legend, as were the accounts of periodic erruptions of house mice, rats and voles. Since then, many investigations have presented …

A Seasonal Study of the Pituitary-Gonadal-Adrenal Axes in Peromyscus Leucopus from Natural Environments
Since Elton’s account and description of population cycles in 1924, a vast amount of research has been undertaken to ascertain what animals have three to four ye a r cyclic fluctuations and what mechanisms are responsible for these seemingly predictable changes. For many years the spectacular …

The Effects of Predator Cues on Vertical Foraging Habits in the White-footed Mouse (Peromyscus leucopus)
… on foraging behavior. I hypothesized that 1) <em>Peromyscus leucopus </em>would climb trees and forage at greater heights if there is coyote urine present and 2) if there are owl pellets present, <em>P. leucopus</em> would avoid foraging at that tree. To explore these hypotheses, giving-up …

Living at the Edge: Effects of Forest Edges on Populations of White -Footed Mice (Peromyscus Leucopus)
To reconcile the apparent contradiction between these results and studies that reported a negative relationship between white-footed mouse density and woodlot area, I reanalyzed the data from the most extensive of these studies. This revealed that the addition of a 7.5 m boundary strip to the …

Habitat Selection in Four Sympatric Small Mammal Species and the Effects of Potential Predators on Peromyscus Leucopus
… predators in relation to habitat selection in Peromyscus leucopus. I also examined habitat selection in three other sympatric species (Blarina brevicauda, Blarina carolinensis, Sorex longirostris). I utilized data fiom 49 sampling sites on National Park Service land; Petersburg National …

ANTI-MOSQUITO BEHAVIOR OF ADULT AND JUVENILE WHITE-FOOTED MICE (PEROMYSCUS LEUCOPUS) (TREEHOLE MOSQUITO, AEDES TRISERIATUS, EPIDEMIOLOGY)
… behavior in the white-footed mouse (Peromyscus leucopus noveboracensis) and to examine effectiveness of such behavior in mice based on age, prior exposure to mosquitoes, and immediate environment.</p><p>I used wild-stock Aedes triseriatus mosquitoes, reared in lab, in experiments with …

Agonistic behavior of <i>Peromyscus leucopus</i> and <i>Microtus pennsylvanicus</i>: implications for population distribution and dynamics
… that interspecific aggression between <em>Peromyscus leucopus</em> and <em>Microtus pennsylvanicus</em> influences levels of ACTH, and thus depresses the reproductive potential of one or both species. Exposure of maturing young to interspecific aggression might be especially critical since …

Effects of low level lead and cadmium on reproduction in Peromyscus leucopus and a study of lead concentration in small mammals from old orchards
… dietary lead and cadmium on reproduction in Peromyscus Jeucopus. Two laboratory studies were conducted. Treatment with combinations of 0, 1 or 4 μ/g lead acetate and/or cadmium chloride was found to have no effect on overall health or reproductive ability of white-footed mice. In a second, …

Effects of Amur Honeysuckle (Lonicera maackii [Rupr.] Herder) Invasion and Removal on Native Vegetation and White-Footed Mice (Peromyscus leucopus) in Mixed-Hardwood Forests of Indiana
… seedlings, as well as white-footed mice(<em>Peromyscus</em> <em>leucopus</em>). Each study site contained two 80 m x 80 m sample areas (removal area where all non-native shrubs were removed and a reference area where no treatment was implemented). Native and non-native vegetation was sampled …

Heat shock proteins as indicators of environmental stress
… environmental stress in the mammalian organism Peromyscus leucopus, three doses of each of two chemical stresses, cadmium chloride and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), were given intraperitoneally for 14 days. Proteins extracted from liver samples were compared by one-dimensional gel …

Engineering Disease Resistance in a Reservoir Species for the Mice Against Ticks Project
… on Lyme disease, where white-footed mice (Peromyscus leucopus) serve as the primary reservoir, we propose embedding immunity into the germline of these animals to disrupt the disease transmission cycle and reduce the prevalence of the disease in the environment. By establishing genome …

Comparative morphology of the adrenal glands of wild and domesticated mice and the effect of captivity on adrenal structure.
… this purpose the adrenals of white-feeted mice(Peromyscus-leucopus noveboracensis), house mice(Mus musculus domesticus), and Garworth Farms - W albino mice(Mus musculus domesticus) were compared. Furthermore, an attempt was made to determine the effect on adrenal structure when wild mice were …

Lyme disease in Indiana : isolation of Borrelia burgdorferi-like organisms from Dermacentor variabilis
… examined from 42 live-trapped white-footed mice (Peromyscus leucopus) for B. burgdorferi. No spirochetes were isolated from these organ cultures. Occasional human cases of Lyme disease in Indiana and the observation of spirochetes similar to B. burgdorferi in size and morphology from D. Variabilis …

Small mammal use of abandoned surface mines in southwestern Virginia
… during four, six-night trapping periods. Peromyscus leucopus noveboracensis and P. maniculatus nubiterrae were the most abundant and widespread mammals encountered on the mines. Other mammalian species were captured infrequently. General habitat types were noted where species other than …
