AnAge entry for Microtus pinetorum

Classification (HAGRID: 03339)
Taxonomy	Kingdom: Animalia Phylum: Chordata Class: Mammalia (Taxon entry) Order: Rodentia Family: Muridae Genus: Microtus
Species	Microtus pinetorum
Common name	Woodland vole
Synonyms	Psammomys pinetorum, Pitymys pinetorum
Lifespan, ageing, and relevant traits
Maximum longevity	3.8 years (captivity)
Source	ref. 671
Sample size	small
Data quality	acceptable
Observations	Voles, in general, are short-lived and show seasonal population crashes, probably due to lack of food. One wild born specimen was about 3.8 years old when it died in captivity [0671].
