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

[edit]

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

Habitat

[edit]

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

[edit]

Diet

[edit]

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

[edit]

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