| Abstract: | We tested the hypothesis that a main function of territory marking
in Eurasian beaver (Castor fiber) is defense of the territory. The results showed
that. (1) beaver colonies with close neighbors scent-mark more often than
isolated ones; (2) the number of scent markings increased significantly with
the number of neighboring territories and individuals, the mean distance to
all other territories, duration of territory occupancy and length of wooded
banks within the territory; (3) the number of scent markings by a colony was
not related to the number of animals in the colony, the distance to nearest
neighbors' main resting-site, or age of beaver; (4) the number of scent mounds
or scent markings in territories with breeding and nonbreeding beaver did not
differ; (5) there was no significant difference in the number of scent markings
during the season (16 April-31 August); and (6) some of the scent mounds
were concentrated at feeding sites, resting sites, and near trails, but most had
no apparent relationship to any of these sites. Therefore we concluded that
scent marking apparently plays an important role in territory defense of the
Eurasian beaver. |
