Abrothrix andina, also known as the Andean Altiplano mouse or Andean akodont, is a species of rodent in the genus Abrothrix of family Cricetidae. It is found in the Altiplano habitat of the Andes from central Peru through Bolivia, south to Argentina and Chile.
Taxonomy
Abrothrix andina is a member of the order Rodentia and family Cricetidae with the genus Abrothrix.
Habitat
Abrothrix andina is a small mammal that is active throughout the Andes, and has been found in altitudes of 4,620 m. The environment consists of small shrubs and is categorizes as having dry summers and snowy winters.
Biology
Diet
Abrothrix andina primarily eats small shrubs during the summer and shrubs and insects during the winters During extreme temperature changes, the gut morphology changes and energy expenditure changes. For example, their metabolic rate may increase by 36.6% during the winter. Their body mass has shown to fluctuate throughout the seasons, as well. Their diet has shown behaviors that exhibit hyperphagy.
Behavior
Abrothrix andina is active throughout the year despite seasonal changes.
