Living at the Edge: Effects of Forest Edges on Populations of White -Footed Mice (Peromyscus Leucopus)
… 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 woodlot area virtually eliminated the negative relationship.

Comparative Phylogeography of Eastern Chipmunks and White -Footed Mice: Population Histories Since the Last Glacial Maximum
Finally, analyses of variation at 6 microsatellite loci among 210 P. leucopus from three sites each around three of the largest cities in Illinois recovered reduced levels of gene flow among sites separated by urban development compared to sites separated by deciduous forest habitat. Mitochondrial …

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
… plants and woody 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 …

Effects of a polychlorinated biphenyl in mice caged at different densities and fed at different nutritional levels
… of dietary PCB (Aroclor 1254) ingestion in white mice (Mus musculus) and in laboratory-reared white-footed mice (Peromyscus leucopus), and to determine if these effects were aggravated by group-caging or feed restriction. The underlying hypothesis was that PCBs may have different …

Habitat Associations and Demography of Small Mammals in 4 Forest Cover Types on Quantico Marine Corps Base, Virginia
… 7 trapping occasions. Five species including white-footed mice (Peromyscus leucopus), northern short-tailed shrews (Blarina brevicauda), eastern chipmunks (Tamias striatus), meadow voles (Microtus pennsylvanicus), and woodland voles (Microtus pinetorum), accounted for approximately 95% of the …

Investigation of how vegetation, small mammal interactions, and land-use determine blacklegged tick abundance
… the microclimatic conditions and sampled for white-footed mice, the primary host of juvenile blacklegged ticks. I found that swallowwort was able to alter the microclimate of a site by providing high relative humidities, low vapor pressure deficits, and small ranges for both variables. I found …

Engineering Disease Resistance in a Reservoir Species for the Mice Against Ticks Project
… species. Focusing 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 …

Lyme disease in Indiana : isolation of Borrelia burgdorferi-like organisms from Dermacentor variabilis
… of blood were 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 …

Wildlife Habitat in the James River Valley, South Dakota
… mammal trapping revealed low densities of mostly white-footed mice (Peromyscus spp.). No vegetation type was more valuable to small mammals than any other. Waterfowl breeding pairs, mostly mallard, blue-winged teal, and wood duck, numbered 244 in 1974 and 638 in 1975, a record flood year. Counts …

Photoperiod, Brain Plasticity, and Behavior
… males of a small photoperiodic rodent species, white-footed mice (Peromyscus leucopus).In Chapter 1 I provide a review of photoperiodism and an overview of the suite of adaptive responses at multiple levels to changing day lengths in a variety of vertebrate species. Among the adaptive responses …

Acorn Contribution to Mammalian Energetics
… food source for many mammal species including white-tailed deer (Odocoileus virginianus), white-footed mice (Peromyscus leucopus), eastern gray squirrels (Sciurus carolinenis), and fox squirrels (S. niger). Oak trees (genus (Quercus) produce variable amounts of acorn mast each autumn. Variation …

Uncertainty analysis in ecological risk assessment modeling
… lesser long-nosed bats, mule deer and cactus mice, at YPG site, are expected to have a reduction in size and weight of offspring. Terrestrial plants are likely to exhibit a reduction in root weight. For APG site, the vulnerable receptors are white-footed mice, white-tailed deer, and cottontail …

Effects of low level lead and cadmium on reproduction in Peromyscus leucopus and a study of lead concentration in small mammals from old orchards
… on overall health or reproductive ability of white-footed mice. In a second, experiment mice were treated with combinations of 0 or 10 μg/g lead acetate and/or cadmium' chloride. Treatment was continued through three generations of mice (P1, Fl, F2); progeny of the P1 were paired with …
