Description

This dataset contains over 32,000 presence-absence occurrences of nine gall wasp species sampled in a common garden of pedunculate oak (Quercus robur) in Flanders (northern Belgium) during five consecutive years (2020–2024). These host-parasite interaction data were collected to investigate how host tree traits (including provenance and phenology) influence gall wasp community structure (Vander Mijnsbrugge et al. 2026).Host tree measurement data, such as phenology features (spring bud burst and autumn leaf senescence), leaf chlorophyll content, tree height, and specific oak provenance details, are not directly formatted within this Darwin Core Archive. However, the complete host measurement dataset and provenance metadata are available in this linked Zenodo repository (Vander Mijnsbrugge & Maebe 2026).We released the data to the public domain under a Creative Commons Zero waiver (http://creativecommons.org/publicdomain/zero/1.0/). We would appreciate however, if you would read and follow these norms for data use (http://www.inbo.be/en/norms-for-data-use) and provide a link to the original dataset whenever possible. If you use these data for a scientific paper, please cite the dataset following the applicable citation norms and/or consider us for co-authorship. We are always interested to know how you have used or visualized the data, or to provide more information, so please contact us via the contact information provided in the metadata or opendata@inbo.be.
