Resource Brief

Mice and voles (Microtus sp. and Clethrionomys sp.) by virtue of their morphology and daily habits are not a highly visible member of the fauna community in the boreal forest. Yet these species represent a larger proportion of biomass on the landscape than brown bears (Ursus arctos horribilus) (Krebs et al. 2001). Within the ecosystems encompassed by the Central Alaska Network, mice and voles consume seeds, fungi and invertebrates and provide a key prey source for raptor species and carnivorous mammals. As a result of their position in the food chain mice and voles play another important ecological role by having the ability to influence species above and below them in the food chain. Since 1991 mice and voles populations have been monitored in Denali National Park and Preserve as part of the previous Long-term Ecological Monitoring program. From these data (cite Rexstad annual reports) and other studies (Krebs et al. 2001) we know that populations of mice and voles vary over space and time. Data from Denali suggests that annual fluctuations in small mammal populations are strongly related to abiotic factors (Rexstad and Debevec 2002). Additionally, the relative abundance of small mammal species is directly related to vegetation composition, so any changes in vegetation composition will likely affect small mammal distribution and patterns of abundance. Thus by monitoring populations of mice and voles, we may detect evidence of affects from human induced change (like global warming) in our ecosystems. These combined characters led the network to include mice and vole species as a logical group to include in the program. ​
