Close to the edge: Spatial variation in plant diversity, biomass and floral resources in conventional and agri-environment cereal fields

Non-crop (segetal) plants in arable systems are commonly perceived simply as “weeds”, i.e. harmful at worst and undesirable at best. The increase in management intensity in European arable systems has vastly reduced the populations of all but the most disturbance-tolerant plant species, negatively impacting the whole agricultural food web. In recent years, efforts have been made to promote agricultural biodiversity through measures such as flower strips and unsprayed field margins. However, studies of their impacts on the arable flora have rarely considered their spatial variation within the crop field. We investigated the spatial distribution of vascular plant species richness and their contribution to the food web via biomass and flower units in conventional and agri-environment cereal fields in six regions of Germany. We studied two types of in-crop measures (extensive cereals without pesticides or fertiliser, and with or without intercropping with flowering species) and one adjacent..., , , # Close to the edge: spatial variation in plant diversity, biomass and floral resources in conventional and agri-environment cereal fields

Main results are contained in *data_sutcliffe_et_al_2024_spatial_variation_cereal_fields*. This is vascular plant data collected at increasing distance from the cereal field edge under different management types. Categorisations of the plant species are contained in *species_data_sutcliffe_et_al_2024_spatial_variation_cereal_fields*.

Data was collected on six farms in Germany in 2021.

耕地系统中的非作物（田间伴生）植物（segetal plants）通常被简单视为“杂草”——即往坏了说是有害物种，往好了说也是不受欢迎的存在。欧洲耕地系统的管理强度持续提升，导致除最耐扰动的植物物种外，其余所有植物种群均大幅缩减，对整个农业食物网造成负面影响。近年来，学界尝试通过花境带、未喷施农药的田埂等措施推动农业生物多样性保护，但现有相关研究在评估这些措施对耕地植物区系的影响时，极少考虑作物田内部的空间变异。

本研究针对德国六个区域的常规种植与农业环境友好型麦田，调查了维管植物（vascular plant）物种丰富度的空间分布特征，及其通过生物量与花部单位（flower units）对食物网的贡献。研究涵盖两类田内管理措施（无农药与化肥的粗放种植小麦，以及搭配或不搭配显花物种间作的麦田），以及一处毗邻……，，，# 贴近田边：常规与农业环境友好型麦田中植物多样性、生物量与花部资源的空间变异
