Multi-Trophic Interactions

Trophic (or feeding) interactions drive the cycling of energy and nutrients in farmland. Insects and other invertebrates feed on plants and in turn are fed on by other insects, spiders, various symbionts, pathogens and vertebrates. A very small proportion of the total species in trophic interactions are pests of agriculture. Most mediate processes that are essential to the cropping cycle, such as the breakdown of dead organisms (crops, weeds, wood, animals), the regulation of pests and the pollination of flowers. These trophic interactions are exceedingly complex and are studied using advanced concepts and methods in organism biology, molecular biology and mathematical modelling.  Through gaining basic knowledge, the topic aims to provide a scientific basis for future management of invertebrate populations in farmland.
