Abrothrix andina, also known as the Andean Altiplano mouse ^[1] or Andean akodont, ^[2] is a species of rodent in the genus Abrothrix of family Cricetidae. ^[3] It is found in the Altiplano habitat of the Andes from central Peru through Bolivia, south to Argentina and Chile. ^[4]

Taxonomy

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

Habitat

Abrothrix andina is a small mammal that is active throughout the Andes, ^[6] and has been found in altitudes of 4,620 m. ^[7] 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 ^[8] During extreme temperature changes, the gut morphology changes and energy expenditure changes. ^[8] 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. ^[8]

Behavior

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