Changes in agricultural systems since the 50's led to considerable changes in rural hedgerow network landscapes. In these landscapes, ecological processes depend on the spatial structure of the network (length of hedgerows, connectedness, grain size). This paper reports on a study of the dynamics of

✦ Synopsis
Structure and dynamics of a hedgerow network landscape over the last thirty years are compared to the current spatial distribution of carabid beetles in hedgerows. Spatial and temporal scales are chosen according to the observed phenomena, and a multiscale approach used. None of the descriptors of landscape at any given period of time is related to carabid assemblages except heterogeneity in 1985. This measure of landscape structure in Brittany integrates part of the recent changes. Carabid assemblages are also related to overall landscape trajectories through time. Relationship between landscape and carabid spatial patterns may be modeled at the stand and landscape levels.
