Effects of agroecological infrastructures on pollinator networks and on the performance of a pollinator-dependent crop: Blackcurrant (Noir de Bourgogne)

Starterd in october 2024

Funding: école doctorale ES

Supervisor: Adam Vanbergen ; cosupervisor: Marie Charlotte Anstett

Abstract

Pollinators and the pollination services they provide are threatened by intensive agriculture, yet agriculture itself relies on this pollination service to assure the yields of many flowering crops of economic importance. Agroecological farming practices offer a solution by simultaneously reducing the pressure on pollinators and providing habitat resources, such as flowering strips of wild plants, to preserve pollinators and pollination services to crops. This PhD project will study the efficacy of flowering strips in supporting the pollinator communities and pollination of a crop of social and economic importance: the blackcurrant (Noir de Bourgogne). They will investigate how flowering strips affect the structure and function of networks of pollinator interactions between the crop and wildflowers and if the wild flowers compete for or facilitate the pollination service to the crop. They will determine the species traits or network properties that support pollination and performance of the crop and they will discover how these effects are modulated in different landscape contexts.
