Pika Ecology

Plateau pikas are a central player in grassland ecology here, and are also keystone species of biodiversity. Our 4-year ecological study has focused on pika-grassland interactions.

Arizona State University PhD candidate Bading Qiuying is now writing up the results of his 43-year study of how pikas' ability to recolonize an area following removal is affected by vegetation condition. Here he puts an ear-tag on a pika; he faces competition in catching them from Tibetan foxes, however!
