It is widely believed that intensive forestry has influenced small mammal population dynamics,and thereby the entire mammalian community in Fennoscandian boreal *** nature of these impacts on the different species is subject to *** live-trapped voles between 2006 and 2009 in 2 commercially harvested forests in south-eastern *** investigated the variation in vole abundance among habitat types(*** forest and clear-cut)and the hypothesis that graminivorous species such as field voles(Microtus agrestis L.)benefit from clear-cuts at the expense of forest dwellers(*** bank vole,Myodes glareolus Schreb.),using fine-scale descriptors of the ground *** could not find support for the hypothesis that field voles show a preference for clear-cuts,and their overall abundance was low,while bank voles were the dominant species in all habitat types,including clear-cuts in the peak and pre-peak *** found a positive association between bank vole abundance and bilberry(Vaccinium myrtillus L.)availability rather than a specific habitat *** field vole density in clear-cuts might be due to variation in local productivity and ground vegetation as well as to large variation in the species temporal *** latter is particularly associated with the widespread decline of field voles in *** has the potential to negatively affect bank vole population dynamics because of the negative effect on bilberry development.
