VOODOO Consortium = Viral eco-evolutionary dynamics of wild and domestic pollinators under global change. International audience. Pollinators face multiple, potentially interacting threats from human activities. The Biodiversa VOODOO project (https://voodoo-project.eu/) seeks to understand how landscape-use, through its impact on floral resources, affects plant-pollinator communities and the transmission of viruses between pollinator species. We present initial results to show how the architecture of plant-pollinator networks varies among agricultural, habitat mosaic, and urban landscapes, with consequences for co-extinctions. We show how modification of floral resources can affect network structure to shape interspecific transmission of viral pathogens and we provide early results that show how niche overlap among species governs the degree of viral pathogen sharing among wild and managed bees.
