The ecosystem service pollination is under threat due to declining populations of pollinators. In this project we will study and how climate change might affect plant-pollinator interactions. We will have a broad focus, including entomophilous crops (frui ts and berries), managed pollinators (honeybees), wild pollinators and wild plants and address questions related to how these four constituents of the pollination system affect each other. We will identify important pollinators to focal crops in Norway a nd the home countries of our international partners (Greece, Argentina and Australia) and how their activity patterns vary with temperature. To better understand how the pollinator community is depending on wild floral resources, in addition to our focal crops, we will also study plant-pollinator interactions in the surrounding vegetation. Finally we will assess the importance of honeybees as pollinators to our focal crops and the surrounding floral community. Our goal is to 1) better understand how surro unding floral resources support the wild pollinator community our focal crops depend upon, 2) How honeybees interact with the crops and the wild flower community, ultimately affecting the community of wild pollinators, and 3) How the entire plant-pollinat or system might be affected by climate change. The project is following recommendations for focal areas of future research outlined in two recent publications co-authored by the PI. We believe the results from the project will be of high value to Norwegia n fruit producers in particular, but also to farmers of entomophilous crops world-wide.
