Mobility of settlements and elements of the biological signaling field of Beavers (Castor fiber) in the basin of the Tadenka River (Prioksko-Terrasny Nature Reserve)

详细

This study was performed in the basin of the Tadenka River (Prioksko-Terrasny Nature Reserve) in the years 2007–2012. We investigated the spatial dynamics of beaver settlements and the stability of various elements of the biological signaling field (scent marks, lifetime of dams and dwellings). The data suggest that a high density of the biological signaling field is an additional sign of possible depletion of food resources. Beavers can rapidly occupy habitats with no elements of the signaling field, which contributed to the formation of their large range.
