Conclusion
Plateau pika changed behaviourally between summer and winter months
Hoarding food was not witnessed
It is possible that they consumed yak faeces in the winter
To further test this hypothesis can use DNA technique created
They consumed similar material (grass) in summer and winter
To survive the winter the plateau pika must adapt behaviourally and physiologically
Not much is known about changes in animals at extremely low temperatures so the plateau pika proves to be an excellent animal to study .....
