Arable ecosystems are shaped by agriculture and the cultivated crops and associated weeds are also indirectly affected by adaptations of agricultural methods, land use and policy to climate change. The theoretical framework, the findings and data as a result of this cumulative thesis provide insights into some underlying biological processes that weeds realise at different scales. This thesis also presents proposals to assure harvest and prevent further biodiversity loss.
