A NEW TECHNIQUE FOR STUDYING THE ACTIVITY OF UNDERGROUND MAMMALS

摘要

A new technique for studying the activity of underground mammals using portable digital voice recorders is developed. Earlier, mole rats were recorded visually, based on emissions of ground above the soil surface. Applying tape recorders, it becomes possible to precisely define if the system of holes is inhabited or not. In addition, it becomes possible to determine the time of the day when the animals move through the system. This technique for studying the activity of the mammals with an underground lifestyle has been applied and approbated for the first time.
