Regulation of root vole population dynamics by food supply and predation: A two-factor experiment

Article Abstract:

The effects of food supply, predation and the interaction between them on the population dynamics of root voles, 'Microtus oeconomus' are reported, by adopting factorial experiments in field enclosures. This two-factor experiment proved the general hypothesis that food supply and predation had independent and additive effects on population dynamics of root voles.

Population dynamics of microtine rodents: an experimental test of the predation hypothesis

Article Abstract:

The predation hypothesis on the interaction between the least weasel (Mustela nivalis nivalis L.) and the field vole (Microtus agrestis L.) is tested. A perturbation of the natural vole-weasel dynamics is involved by increasing the number of predators.

Predation rate, prey preference and predator switching: experiments on voles and weasels

Article Abstract:

Weasels appear to prefer bank voles to field voles in the laboratory. Predation for weasels in this study is primarily affected by prey aggregation and availability as well as suitable hunting habitat.
