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.本仓库包含手稿《阿根廷潘帕斯起伏草原中作物-田边界面的杂草种子库反映样地尺度遗留效应而非短期作物类型特征》所使用的原始数据与R脚本。 本数据集涵盖阿根廷潘帕斯起伏草原12个农田田边生境采集的种子库样本的物种丰度数据，样本采用幼苗萌发法获取，并以样地为单位进行聚合。本仓库同时包含描述采样设计、样地标识、作物类型及空间结构的元数据。 本R脚本可复现手稿中呈现的全部分析内容，包括群落组成分析（非度量多维尺度分析（Non-metric Multidimensional Scaling，NMDS）、置换多元方差分析（Permutational Multivariate Analysis of Variance，PERMANOVA））、针对物种丰富度与总丰度的广义线性混合模型、基于功能性状的分析，以及敏感性分析。 本仓库旨在确保研究结果可完全复现，并为未来针对农业景观中杂草种子库动态与生物多样性干预措施的研究提供基准数据集。
