Lifespan, ageing, and relevant traits

Maximum longevity
Not yet established
Observations

Voles, in general, are short-lived and show seasonal population crashes, probably due to lack of food. These animals are estimated to live up to 1.8 years [0542], but without further studies their maximum longevity cannot be determined.
