Molecular regulation of vasopressin receptor among (mostly) monogamous prairie voles
… and environmental variation. Although prairie voles are socially monogamous, they vary in sexual fidelity; faithful prairie voles are described as intra-pair fertilizing (IPF), while unfaithful voles are extra-pair fertilizing (EPF). EPF males have large home-ranges and frequently mate with …

The Ontogeny of Thermoregulatory Abilities in Neonatal Cotton Rats and Montane Voles
… TNZ for cotton rats was 33-35°C and for montane voles around 30°C. Since norepinephrine (NE) stimulated BAT metabolism, the effect of NE was measured at thermoneutrality in 2, 4, 6-8 and 12 day old cotton rat neonates, and in 4, 8, 12 and 16 day old montane vole neonates. Two day old cotton rats, …

The Role of Plant Chemical Defenses in The Nutritional Ecology of Voles
… and population density of microtine rodents (voles and lemmings), the impact of secondary plant compounds on forage quality is largely unknown. This thesis reports results of studies conducted to examine the effects of plant chemical defenses on the individual performance, food habits, and …

The nutritonal ecology of meadow voles (Microtus pennsylvanicus) under differing environmental conditions
… morphology and physiology in meadow voles (Microtus pennsylvanicus) were investigated. Voles were randomly divided (10 in each group) and placed in 15-day treatment regimes [cold (5 C) and warm (21 C), daylengths long (18L:6D) and short (6L:18D), and diets of high fiber (50% neutral …

Laboratory evaluation of some Malus cultivars and hybrids to attack by pine voles
A tank test technique was developed to evaluate the resistance of one-year-old stems of 111 Malus rootstock cultivars and hybrids to pine vole damage. The tank fest proved to be an excellent method for: testing several clones at one time; providing the animals with more of a natural environment; …

The Effects of Food, Cover and Competition on Demography, Dispersal and Density of Voles
… dispersal, and population dynamics of prairie voles (Microtus ochrogaster) and meadow voles ( Microtus pennsylvanicus) populations that occupied habitat patches that differed in availability of high quality food and amount of vegetative cover. I tested a series of a priori hypotheses regarding …

Effect of Food Availability and Predation on the Population Dynamics and Spacing Behavior of Prairie Voles
Microtine rodent (lemmings and voles) populations often undergo seasonal or multi-annual fluctuations in density. Although a number of single factors have been proposed as the causal agent of these fluctuations, no one has demonstrated convincingly that a single-factor mechanism is responsible. …

Bioenergetics and nutrition of the pine vole (microtus pinetorum) in two Virginia apple orchards
… lactating females, and growing juvenile pine voles. Adult pine voles showed a seasonal cycle in daily maintenance energy requirements. Winter was energetically the most expensive season. Requirements during the summer season were the lowest of all seasons. There was no significant difference …

The Effects of USDA Farm-Bill Restoration Programs on Prairie Voles (microtus ochrogaster) in the Barrens Region of Kentucky
… CRP and CREP plant mixes will have on prairie voles (Microtus ochrogaster) populations. Small mammal trapping will be used to assess crucial variables such as recruitment, population density, body mass, survival, habitat choice, and home range will be measured to quantify the relative success …

Effects of soil moisture and al-nitrilotriacetate on yeild chemical composition and digestibility of ryegrass (Lolium multiflorum, L.) by meadow voles
… Two digestion trials were conducted with meadow voles (Microtus pennsylvanicus) fed forage harvested from the greenhouse experiment. Voles were housed in stainless steel metabolism cages for total collections of feed and feces. A 2-day preliminary, during which voles were fed 100% ryegrass, …

Mathematical modeling of zoonotic disease transmission under the impact of land use change
… describes spillover of Puumala virus from bank voles to humans during land conversion. Our model introduces a land conversion index to capture the dependence of the carrying capacity and the death rate of bank voles on the proportion of converted land. This index is then used to examine how …

Nutritional implications of coprophagy and cecal function in two microtine rodents (Microtus pennsylvanicus and Microtus pinetorum)
… was manipulated. The nutritional response of the voles to a high and low quality diet was measured after the coprophagic or cecal component was eliminated from the digestive process. The nature of the nutritional response was determined by measuring food consumption, fecal production, diet …

Photoperiod and nutritional influences on reproduction, growth and pelage changes in the pine vole
… available. In a laboratory experiment adult voles fed a rabbit chow diet supplemented with apple consumed less digestible energy but had higher body weights and more body fat, and males had heavier testes than those fed only chow. Adults on a 14L:10D photoperiod had higher values for …

Social defeat and oxytocin regulation of social avoidance and stress-related signaling proteins
… Particularly, social defeat in prairie voles (Microtus ochrogaster) advantageously allows the study of female subjects due to their spontaneous display of aggression towards unfamiliar conspecifics after pair bond formation. Once defeated, prairie voles exhibit social avoidance to …

The effects of mammalian herbivores on successional grasslands in central Illinois
… composition of these plant communities. Mice and voles consume large seeds, and rabbits disperse small seeds endozoochorously. Voles, rabbits, and deer prefer certain plant species, particularly leguminous forbs, over graminoids. Deer, rabbits, and voles often damage woody plants and seedlings. I …

Habitat Associations and Demography of Small Mammals in 4 Forest Cover Types on Quantico Marine Corps Base, Virginia
… eastern chipmunks (Tamias striatus), meadow voles (Microtus pennsylvanicus), and woodland voles (Microtus pinetorum), accounted for approximately 95% of the total number of individuals captured. Overall relative abundance and species composition of small mammals differed significantly across …
