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 …

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 …

Deciphering the Molecular Basis of the Species Barrier in Prion Disease Using Bank Vole PrP
… referred to as the species barrier. Bank vole (Bv) PrP is an exception, as it serves as an efficient substrate for templated misfolding with essentially all prions identified to date. This universal acceptor phenotype is a rare example of structural compatibility between PrPC and PrPSc in …

Seasonal variation in the natality, mortality, and nutrition of the pine vole in two orchard types
Pine voles (Microtus pinetorum) were collected for one year in a maintained and an abandoned orchard. Higher densities of voles were indicated in the maintained orchard. Estimates of mortality were lower and reproduction was higher in the maintained orchard. Net reproductive rates indicated a …

Effects of a Small Mammalian Herbivore on a Grassland Undergoing Restoration
This thesis examines the effects of the prairie vole, Microtus ochrogaster, on a grassland undergoing restoration. The study addresses these effects with respect to treatment plots (vole-enhanced enclosures and vole-excluded exclosures) and control plots, which have not had the small mammal …

Nutritional implications of coprophagy and cecal function in two microtine rodents (Microtus pennsylvanicus and Microtus pinetorum)
… and cecal function were examined for the meadow vole (Microtus pennsylvanicus) and the pine vole (Microtus pinetorum) as diet quality 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 …
