Abstract: Objectives 1. To quantify demographic changes and patterns in dental variation, etc. in montane voles, over different habitats over a long period. 2. To describe food habits of montane voles and long-tailed voles and use this analysis to assess role of food in demographic patterns and possibly competition. Findings and Status 1. Population patterns vary within one year, at different types of sites, for montane voles. 2. In population of m. longicaudus monitored for 7 years, numbers did not reach extremes in density. This species has broad habitat and is more widespread in GTNP than previously reported.
