布拉德利，O。Department of Forest Biodiversity, Institute for Forest Biodiversity & Nature Conservation, Austrian Research Centre for Forests (BFW), Vienna, Austria, Email: owen.bradley@bfw.gv.at Forest soil biodiversity is critical for maintaining forest health, ecosystem stability, nutrient cycling, and carbon sequestration.However, the intricate life in forest floors that drives these essential forest functions remains one of the least understood aspects of forest ecosystems.This study investigates the composition and drivers of soil biodiversity along an altitudinal gradient in beech to spruce-fir-beech forests of the Northern Limestone Alps in Austria.它研究了土壤微生物群落如何由环境梯度和森林结构塑造。By linking soil biodiversity metrics to soil properties and forest biodiversity indicators, this research aims to identify the key drivers of mountain forest soil biodiversity and the interactions between above- and below-ground biodiversity.Thirty forest plots in and around the Gesäuse and Kalkalpen National Parks were surveyed for forest biodiversity indicators, including tree species, physical structure, deadwood, and tree-related microhabitats.The topsoil and organic layers of these plots, all situated on limestone, were described and sampled for physicochemical, PLFA, and eDNA analysis targeting bacteria, fungi, and arthropods.统计分析正在进行中； however, preliminary results indicate that microbial community structure correlates with soil pH, organic matter content, plot deadwood volumes, and altitude, among other factors.这项研究强调了土壤和森林生物多样性的相互联系及其在维持奥地利山区森林中生态系统连通性方面的作用。通过确定土壤生物群多样性的主要驱动因素，这项研究有助于森林保护和恢复策略，从而为森林经理提供了减轻生物多样性损失的工具。未来的工作应包括从硅质父母材料中的森林土壤，以更好地了解更多奥地利山区森林类型的土壤生物多样性，并整合长期监测，以更好地了解在不断变化的环境条件下森林土壤生物多样性的时间动态。
