Behaviour and resource use of two competing vole species under shared predation risk

Original language description

Indirect interaction between two competing species via a shared predator may be an important determinant of population and community dynamics. We studied the eVect of predation risk imposed by the least weasel Mustela nivalis nivalis on pace use, foraging and activity of two competing vole species, the grey-sided vole yodes rufocanus, and the bank vole Myodes glareolus. The experiment was conducted in a large indoor arena, consisting of microhabitat structures providing food, shelter, trees for refuge and separated areas with high and low predation risk. Voles were followed for 5 days: 2 days before, 1 day during and 2 days after the presence of weasel. Our results suggest an eVect of weasel presence on the vole community. Voles of both species shiftedtheir activity from risky to less risky areas, climbed trees more often and were less active. Seed consumption was not affected by weasel presence. The time spent in the risky and less risky area did not differ between species, but bank

Chování a využívání zdroje u dvou kompetičních hrabošů sdílejících společné riziko predace

Czech description

Experimenty s kolčavou a dvěma druhy norníků, Myodes glareolus a rufocanus, provedené v aréně naznačují, že přítomnost predátora má vliv na prostorové chování, aktivitu a využití zdrojů. Samci trávili více času v rizikové části arény než samice. Norník rudý trávil více času na stromech než norník šedavý.
