Taxonomy

Abrothrix andina is a member of the order Rodentia and family Cricetidae with the genus Abrothrix.[5]

Habitat

Abrothrix andinus is a small mammal that is active throughout the Andes. [6] The environment consists of small shrubs and is categorizes as having dry summers and snowy winters.[6]

Biology

Diet

Abrothrix andina primarily eats small shrubs during the summer and shrubs and insects during the winters[7] During extreme temperature changes, the gut morphology changes and energy expenditure changes.[7] For example, their metabolic rate may increase by 36.6% during the winter.[6] Their body mass has shown to fluctuate throughout the seasons, as well.[6] Their diet has shown behaviors that exhibit hyperphagy.[7]

Behavior

Abrothrix andina is active throughout the year despite seasonal changes.[6]
