Spatial dynamics of wood mouse (Apodemus sylvaticus) in an agricultural landscape under intensive use in the Mont Saint Michel Bay (France)

摘要: Over the last decades intensification in agricultural use has lead to changes landscape structure and composition. Seasonal fluctuations of wood mouse (Apodemus sylvaticus) are well known cultivated landscapes, but not explained. The main question relates fate individuals during summer. hypothesis a seasonal dispersal from hedges crops was investigated polder Mont Saint Michel Bay (France) at different scales using GIS. Field scale parameters were analysed relation abundance mosaic. results tend demonstrate that dilution population due toward could be factor explaining drops hedges. Hedgerows act as source habitat spring whereas field colonisation rate depends on crop quality heterogeneity matrix for presence been studied. Variations vegetation cover plot its surroundings appear determine mice Results may have implications terms pest management and/or food webs preservation landscapes.
