Stream and terrestrial ecosystems are intimately connected by riparian zones that support high biodiversity but are also vulnerable to human impacts. Landscape disturbances, overgrazing, and diffuse pollution of agrochemicals threaten riparian biodiversity and the delivery of ecosystem services in agricultural landscapes. We assessed how terrestrial invertebrate communities respond to changes in riparian vegetation in Romanian agricultural catchments, with a focus on the role of forested riparian buffers. Riparian invertebrates were sampled in 10 paired sites, with each pair consisting of an unbuffered upstream reach and a downstream reach buffered with woody riparian vegetation. Our results revealed distinct invertebrate community structures in the two site types. Out of 33 invertebrate families, 13 were unique to either forested (6) or unbuffered (7) sites. Thomisidae, Clubionidae, Tetragnathidae, Curculionidae, Culicidae, and Cicadidae were associated with forested buffers, while Lycosidae, Chrysomelidae, Staphylinidae, Coccinellidae, Tettigoniidae, Formicidae, and Eutichuridae were more abundant in unbuffered sites. Despite statistically equivocal results, invertebrate diversity was generally higher in forested riparian buffers. Local riparian attributes significantly influenced patterns in invertebrate community composition. Our findings highlight the importance of local woody riparian buffers in maintaining terrestrial invertebrate diversity and their potential contribution as a multifunctional management tool in agricultural landscapes.

河岸植被结构影响农业景观中的陆地无脊椎动物群落

河流和陆地生态系统由支持高生物多样性但也易受人类影响的河岸带紧密相连。景观扰动，过度放牧和农药的扩散污染威胁着河岸生物多样性和农业景观中生态系统服务的提供。我们评估了陆生无脊椎动物群落对罗马尼亚农业流域的河岸植被变化的反应，重点是森林河岸缓冲带的作用。在10个成对的地点采样了河岸无脊椎动物，每对包括无缓冲上游河段和下游河床，并由木质河岸植被缓冲。我们的研究结果揭示了两种地点类型中不同的无脊椎动物群落结构。在33个无脊椎动物家庭中，13个对于森林（6）或无缓冲（7）站点是唯一的。forest科，夜蛾科，四线虫科，弯孢科，葫芦科和cad科与森林缓冲液相关，而在未缓冲部位，石蒜科，金眼科，葡萄球菌，球虫科，i科，甲虫和Eu科更为丰富。尽管统计上的结果模棱两可，但在有森林的河岸缓冲带中，无脊椎动物的多样性通常较高。本地河岸属性极大地影响了无脊椎动物群落组成的模式。我们的发现凸显了当地木质河岸缓冲带在维持陆地无脊椎动物多样性中的重要性及其作为农业景观中多功能管理工具的潜在贡献。Ci科和Ci科与森林缓冲液相关，而Ly科，葫芦科，葡萄球菌，球藻科，T形科，甲虫科和Eu科在非缓冲位点更为丰富。尽管统计上的结果模棱两可，但在有森林的河岸缓冲带中，无脊椎动物的多样性通常较高。本地河岸属性极大地影响了无脊椎动物群落组成的模式。我们的发现凸显了当地木质河岸缓冲带在维持陆地无脊椎动物多样性中的重要性及其作为农业景观中多功能管理工具的潜在贡献。Ci科和Ci科与森林缓冲液相关，而Ly科，葫芦科，葡萄球菌，球藻科，T形科，甲虫科和Eu科在非缓冲位点更为丰富。尽管统计上的结果模棱两可，但在有森林的河岸缓冲带中，无脊椎动物的多样性通常较高。本地河岸属性极大地影响了无脊椎动物群落组成的模式。我们的发现凸显了当地木质河岸缓冲带在维持陆地无脊椎动物多样性中的重要性及其作为农业景观中多功能管理工具的潜在贡献。无脊椎动物的河岸缓冲带中的无脊椎动物多样性通常较高。本地河岸属性极大地影响了无脊椎动物群落组成的模式。我们的发现凸显了当地木质河岸缓冲带在维持陆地无脊椎动物多样性中的重要性及其作为农业景观中多功能管理工具的潜在贡献。无脊椎动物的河岸缓冲带中的无脊椎动物多样性通常较高。本地河岸属性极大地影响了无脊椎动物群落组成的模式。我们的发现凸显了当地木质河岸缓冲带在维持陆地无脊椎动物多样性中的重要性及其作为农业景观中多功能管理工具的潜在贡献。
