Microtus is a genus of small rodents commonly known as voles. They are part of the family Cricetidae and are found in various habitats, including grasslands, forests, and wetlands. Voles are characterized by their stocky bodies, short tails, and small ears. They primarily feed on grasses, seeds, and roots. These rodents play a significant role in their ecosystems as prey for various predators, including birds of prey and foxes. Voles are also known for their burrowing habits, which can impact soil health and plant growth. Their populations can fluctuate significantly, often leading to boom-and-bust cycles.
