Diet of Andean Leaf-Eared Mice (Phyllotis) Living at Extreme Elevations on Atacama Volcanoes: Insights From Metagenomics, DNA Metabarcoding, and Stable Isotopes. [PDF]

Ecol Evol
On the flanks of > 6000 m Andean volcanoes that tower over the Atacama Desert, leaf‐eared mice (Phyllotis vaccarum) live at extreme elevations that surpass known vegetation limits. We used a combination of metagenomics, DNA metabarcoding, and stable isotope analyses to investigate the diet of mice living in these extreme environments.
