Data and code for: Weed seed banks at the crop–margin interface reflect site-level legacies rather than short-term crop identity in the Rolling Pampas

This repository contains the raw data and R scripts used in the manuscript “Weed seed banks at the crop–margin interface reflect site-level legacies rather than short-term crop identity in the Rolling Pampas”. The dataset includes species-level abundance data from seed bank samples collected in field margins across 12 agricultural fields in the Rolling Pampas, Argentina. Samples were obtained using a seedling emergence method and aggregated at the plot level. The repository also includes metadata describing sampling design, site identifiers, crop identity, and spatial structure. The R script reproduces all analyses presented in the manuscript, including community composition analyses (NMDS, PERMANOVA), generalized linear mixed models for species richness and total abundance, trait-based analyses, and a sensitivity analysis. This repository is intended to ensure full reproducibility of the results and to provide a baseline dataset for future studies on weed seed bank dynamics and biodiversity interventions in agricultural landscapes.
