Muskox female adult and calf in August 2019. (C) An example of muskox
fecal sample.
Ten muskox fecal samples were collected; six from muskox female adults
and four from calves (four pairs of mother and calf and two females with
no calf, Figure 1B; muskox feces, Figure C). Among them, eight samples
comprise four pairs of mother and calf. All samples had been kept in
Ethanol solution (99%) until the DNAs were extracted. We also sampled
leaves, stems, and fruits of 8 plant species as candidate prey sources
from the ground where the muskox foraged.
