Curriculum Vitae and research interest in short

He (MSc in Insect Pest Management, PhD in Entomology) has been an agro-ecologist for 30 years with broad expertise of farmland ecosystems, the pressures and constraints on farmland wildlife and development of remedial measures including exploitation of ecosystem services. He is an Associate professor at the University of Sussex. His research focusses predominantly on the ecology and management of beneficial insects (natural enemies and pollinators) and those important in the diet of farmland birds. recently completed coordinating the FP7 project QuESSA. This project quantified the impact of semi-natural habitats on key ecosystem services such as pest control and pollination. Many studies were conducted on the spatial distribution of insects on farmland in relation to within field and surrounding attributes (weed cover, soils and non-crop habitats) in order to identify the controlling factors and so aid the development of management techniques. The scale of these studies extended over time from single fields to landscapes. Alongside these a range of studies were conducted to evaluate the efficacy of different types of pest natural enemies. He has also conducted research to develop agri-environment schemes to support farmland birds, invertebrates and plants.

Presentation title

Landscape management and preservation of biodiversity

ABSTRACT - Birds and invertebrates are two taxa that have declined in recent decades attributed to intensive agricultural practices. The 47-year long Sussex study run by the Game and Wildlife Conservation Trust showed that many arthropod taxa have declined and this has been attributed mostly to the direct and indirect effects of pesticides. This has had consequences for animals higher up the food chain, especially so for birds. Agri-environment schemes have been deployed to some extent to help reverse declines. Assessments of individual agri-environment and semi-natural habitats show their value to beneficial invertebrates, which is typically driven by their plant composition, however their impact at local and landscape scales will depend on how they are deployed. Birds and pollinators respond positively to increases in the proportion of semi-natural habitats. Flower-rich habitats are highly attractive to pollinators and can enhance abundance at farm-scales, however, landscape maps generated in QuESSA reveal gaps in our landscapes. Likewise, pest natural enemies show heterogeneous distributions at local to landscape levels which may be attributed to lack of semi-natural habitats. Local management practices and the type and proportion of semi-natural habitats can be used to increase levels of biocontrol.
