Plants growing in the extreme tundra climate usually have a short life cycle or a limited growing season. The tundra is a treeless biome in which low temperatures and short growing seasons limit plant growth above a certain height. The present study performed a comparative analysis on the responses to 4-18 h of food deprivation in the common vole (Microtus arvalis) and the tundra vole (Microtus oeconomus).
