Dr Macfadyen’s research examines the interactions between species and how this relates to agroecosystem function, focussing on insect pests in grain cropping landscapes.
Her research is split between two main themes:
-How local management decisions (e.g. the use of particular crop rotations or insecticides) influence invertebrate community structure and function on farms.
-How wider–scale landscape structure and configuration (eg amount of arable land, woody vegetation and perennial pastures etc.) influences biodiversity and therefore the provision of ecosystem services such as natural pest control.
