Marking activity of common beaver (Castor fiber L.) in the settlements of channel type. Dynamic aspect
submitted by TravRap 38 minutes ago
Features of the marking activity of beavers in the channel-type settlements are considered. On the basis of statistical data it was determined that the signal hillocks may be recommended for investigation of dynamic indexes of scent marking by beavers. On the basis of quantitative methods the rol...
