Abstract:
The various activities of the wild boar (Sus scrofa), such as nesting, feeding, and rooting, may impact a wide array of taxa and ecological processes, but there is still controversial evidence about the effects of wild boars on small mammal populations. Here, we tested whether a negative effect of wild boar abundance on the wild populations of the wood mouse (Apodemus sylvaticus) does occur along 24 transects in Sardinia Island, Italy. We found a significantly negative linear relationship between the rooting intensity of wild boars and the density of mice in each transect. Our study, therefore, suggests that wild boars may have a negative impact on mice populations. Monitoring the populations of wild boar would be also useful for the management of free-ranging rodent populations throughout Europe.
