The Gansu zokor are highly aggressive , and encounters between of two animals may end in the death or injur y of one of them.

The results showed that when an intruder was introduced , the test animal almost always shifted its latrine location to the intruder’s side. The Gansu zokor can detect the conspecific odor. In nonbreeding season , the odor of urine and faeces of Gansu zokors prolongs excavation of homosexual intruders and play
