Body Size And Growth Patterns Of Microtus Pennsylvanicus (Ord.) In Chesapeake, Virginia, Sara E. Bell
Body Size And Growth Patterns Of Microtus Pennsylvanicus (Ord.) In Chesapeake, Virginia, Sara E. Bell
Biological Sciences Theses & Dissertations
From Dec 2002-Feb 2008, a capture-mark-release study was conducted on 2 Chesapeake, Virginia populations of meadow voles (Microtus pennsylvanicus). The study sites were effectively 1 ha grids in old fields. Two modified live Fitch-type traps were placed at 12.5 m intervals on grids that were trapped for 3 days each month. In northern North America, voles have distinct breeding cohorts (spring and autumn), experience autumn and winter weight loss, demonstrate both delayed growth and sexual maturation in autumn-born young, have lifespans less than 15 weeks, and average about 35-50 g as adults. Chesapeake voles bred year-round, experienced no …

The Distribution Of Rice Rats (Oryzomys Palustris) And Meadow Voles (Microtus Pennsylvanicus) In Tidal Marsh Communities On The Eastern Shore Of Virginia, Allison L. Sowell
Biological Sciences Theses & Dissertations
Two tidal marsh sites were selected for live trapping of small mammals on the Eastern Shore of Virginia. Trap grids were established at site and animals were trapped and tagged each month for one year. Habitat variables were measured at the peak of the growing season and again in late winter when vegetation was at its least luxuriant. ANOVA and multiple regressions were used to analyze the relationships between rice rats and meadow voles and associated variables related to habitat structure.
ANOVA revealed where rice rats and meadow voles differed in habitat preferences. Meadow voles were consistently captured in association …
