Dissertation title: 

The landscape drives the stream: unravelling ecological mechanisms to improve restoration

Group:
Promotor: Piet Verdonschot

Abstract:

The aim of this thesis was to unravel the mechanisms by which land use affects structure and functioning of lowland stream ecosystem, and improve stream restoration. To this end we: 1- evaluate over 40 years of stream restoration the influence of policy goals on stream restoration efforts, the biophysical restoration objectives, the restoration measures, the scale on which these measures were applied, and the monitoring efforts to fuel future perspectives; 2- unravel the mechanisms by which runoff affects sediment composition and macroinvertebrates in deposition zones of lowland stream ecosystems; 3- determine if stream food resource and habitat are land use specific and if they structure macroinvertebrate communities; 4- assess the impact of catchment land use on the structure and functioning of stream ecosystems; 5- apply a novel stream restoration approach to restore sandy‚Äźbottom lowland streams degraded by channelization and channel incision.
