meadow voles, Microtus pennsylvanicus, contributes to this pattern.
Small mammal capture frequencies varied during the 2 sampling periods; seroprevalence for pocket mice, prairie voles, and harvest mice increased, and that for
meadow voles (M.
The findings, published in Environmental Toxicology and Chemistry, found that low chronic doses of gamma radiation at 50 to 200 times background levels had beneficial effects on the stress axis and the immune axis of natural populations of
meadow voles. The paper provides evidence of hormesis--when low doses of a harmful agent have beneficial effects--from the only large-scale, long-term experimental field test ever conducted on the chronic effects of gamma radiation on mammals.
Remarks: The
Meadow Vole currently occurs from northern Georgia in the east and northern New Mexico in the west northward to the Northwest Territories of Canada and Alaska (Kurta 1995, map, 171).
THE speediest mammal is the female
meadow vole which can produce litters of up to eight young, 17 times a year, from the age of 25 days.

Food preferences of
meadow vole (Microtus pennsylvanicus) in relation to habitat affinities.
These results are comparable to those observed in a similar study with the promiscuous
meadow vole Microtus pennsylvanicus.
Our study was designed to test the assumptions required by the outbreeding hypothesis, using populations of the
meadow vole (M.
Previously, two well-characterized hantaviruses had been isolated from different species in the United States: Seoul virus from Rattus norvegicus (Norway rat) and Prospect Hill virus from Microtus pennsylvanicus (
meadow vole) (5).
