Drivers of viral prevalence in landscape-scale pollinator networks across Europe: Honey bee viral density, niche overlap with this reservoir host and network architecture

We looked at 144 plant-pollinator networks from 48 sites divided over 4 countries along an urbanization and agricultural intensification gradient to assess how landscape, honey bees, and plant-pollinator network structure affect the prevalence and load of three honeybee RNA viruses (DWV-A, DWV-B, and BQCV) in wild bees and hoverflies. We provide information on plant-pollinator interactions, land use in the study landscapes, plant-pollinator network structure, niche overlap between wild bees and honeybees, and data on prevalence and load of analyzed honeybees and wild pollinators. The R code used for statistical analysis and creation of figures in the accompanying paper is also provided.

We analysed plant-pollinator networks in 48 landscapes over 4 countries (France, Germany, Poland, Switzerland), during three sampling rounds (144 visits in total), and looked at plant-pollinator network structure and how this affected the presence of three types of RNA virus in wild pollinators (DWV-A, DWV-B, and BQCV). We analyzed plant-pollinator network structure, the presence of viruses, landscape composition, and vegetation. The dataset does not contain any threatened species. All missing data represented as NA.

#### Description of the data and file structure

This dataset contains information on raw landscape composition, plant-pollinator interactions, vegetation composition and viral analysis of pollinators. All data is contained in the zipped folder \"Raw_data_Proesmans_ea_EL_v2.zip\" (Raw_data_Pro..., , **Changes after Oct 29, 2025:** 

27/11/2025: Per suggestions of the referee, I have updated the R scripts. Changes are:

-In all R scripts, the name of the manuscript, authors and corresponding author were added. Additionally, the version numbers of used packages were added to guarantee replicability

-In the overarching analysis script, annotations were added to link figures and tables to their numbers in the manuscript. Nothing was changed in the syntax, so the code should run exactly the same way as it did in the previous version.

-The file location in setwd() was removed, and instead I have annotated instructions on how to set the working directory, and which files should be present in the folder for the script to run.

-The main change is that I added two new scripts that show how we calculated the amount of nectar (in µg per m²) and the nectar diversity (mean plot-level Shannon diversity, averaged over the site-level).

-To make this calculation easier, I have merged all th...
