Abstract Agricultural intensification threatens biodiversity, requiring a shift to agroecological farming. Identifying locally-specific management practices that can effectively enhance biodiversity can help guide farmland conservation efforts. We assess the effect of management practices and environmental variables on arthropod diversity under varying vineyard management regimes in a South African biosphere reserve. We also determine whether the implementation of these practices and their combined effect on arthropods differ between integrated and organic vineyards. Arthropod morphospecies richness and evenness were assessed for different taxonomic groups (spiders, beetles, and true bugs), in different positions in the crop (ground level, on cover crops, and on vine foliage) and for different feeding guilds (herbivores, detritivores, and predators). Percentage herbaceous vegetation cover had a consistent positive effect on morphospecies richness across taxa, microhabitats, and guilds. Other vegetation-related variables, such as volume of plant litter, plant species richness, and plant height positively influenced several of the biodiversity responses. We did not detect any negative effect of agrochemicals used in an integrated approach, or a strong effect of overall farming approach (organic vs. integrated) on the species richness or evenness of any of the focal taxa, sampled positions, or guilds. These results indicate that the maintenance of dense and diverse cover crops is a strategic way to enhance vineyard arthropod diversity where other management practices are already implemented sensitively. This highlights that minimal adjustment of management practices can greatly benefit farmland biodiversity conservation and is in keeping with the ethos of the concept of a biosphere reserve.

多样化的草本覆盖作物促进了不同管理制度下葡萄园节肢动物的多样性

摘要 农业集约化威胁到生物多样性，需要转向农业生态农业。确定可以有效增强生物多样性的当地特定管理实践有助于指导农田保护工作。我们评估了管理实践和环境变量对南非生物圈保护区不同葡萄园管理制度下节肢动物多样性的影响。我们还确定这些做法的实施及其对节肢动物的综合影响是否在综合葡萄园和有机葡萄园之间有所不同。对不同分类群（蜘蛛、甲虫和真虫）、作物中不同位置（地面、覆盖作物和藤蔓植物的叶子）和不同饲养群（食草动物、食腐动物、和掠食者）。草本植被覆盖百分比对跨分类群、微生境和行会的形态物种丰富度具有一致的积极影响。其他与植被相关的变量，例如植物凋落物的体积、植物物种丰富度和植物高度，对一些生物多样性响应产生了积极影响。我们没有检测到综合方法中使用的农用化学品的任何负面影响，或整体耕作方法（有机与综合）对任何焦点分类群、采样位置或行会的物种丰富度或均匀度的强烈影响。这些结果表明，在其他管理实践已经敏感实施的情况下，保持密集和多样化的覆盖作物是提高葡萄园节肢动物多样性的战略方法。
