Predicting spatial and temporal habitat use of rodents in a highly intensive agricultural area

摘要: Landscape modifications in combination with a highly intensive agriculture are known to have negative impacts on farmland biodiversity. Small rodents play crucial role agricultural ecosystems because they provide important ecosystem functions. They links food webs, but also pest species various kinds of crops. Here, we want find trade-offs between small rodent conservation and control agriculture. We predicted abundance, richness community composition relation landscape scale effects (measured as % arable land along gradient complexity), local (agricultural fields vs. semi-natural natural habitats, well vegetation cover) temporal variations within growing season (before after the crop harvest) simultaneously. Results show that increasing cover increased abundance influenced harvest. Local lowest grasslands compared whereas which land. Apodemus agrarius (striped field mouse) was most abundant margins Myodes glareolus (bank vole) kettle holes, isolation these habitats increased, decreased. A compromise nature protection would be an interspersed by arranged dispersal distances, providing high cover. Grasslands can act sink may reduce spillover into facilitating control. Special attention has paid such source habitat conservation.
