Abstract
Field sampling will investigate the extent and nature of the predatory beetle community and their prey 9minly slugs) in the control and improved grassland treatments at Sourhope. A molecular dietary analysis will determine the composition of beetle prey. Controlled field and laboratory experiments will follow the passage of a 13C pulse through the system to test the hypothesis that there are fast and slow routes of carbon transfer in to the higher trophic levels. A manipulative experiment will investigate whether top-down effects on slugs are responsible for determining the composition of the plant community. These studies will address the overall objective of understanding the functional role or higher trophic levels in the soil at Sourhope and their effects on the plant community.
