Intensification of anthropogenic land use is a major threat to biodiversity and thus to essential ecosystem services provided by insects. Rove beetles (Coleoptera: Staphylinidae), which react sensitively to habitat changes, are species-rich colonizers of vertebrate cadavers and contribute to the important ecosystem service of carrion decomposition. The unveiling of anthropogenic and environmental drivers that modify carrion-associated rove beetle communities should improve our understanding of the plasticity of cadaver decay. We report the presence of 80 rove beetle species on 65 decomposing piglet cadavers at forest sites characterized by a gradient of management intensity across three geographic regions in Germany. Local and landscape drivers were revealed that shape beetle abundance, diversity, and community composition. Forest management and regions affect rove beetle abundance, whereas diversity is influenced by local habitat parameters (soil pH, litter cover) and regions. The community composition of rove beetles changes with management intensification by promoting generalist species. Regarding single species, and are linked to unmanaged forests and to highly used forest stands. The spatial information provided about carrion-associated rove beetle communities in German forests is not only of carrion-ecological but also of forensic entomological interest.
人为土地利用的强化是对生物多样性的重大威胁，进而也是对昆虫所提供的基本生态系统服务的重大威胁。隐翅虫（鞘翅目：隐翅虫科）对栖息地变化反应敏感，是脊椎动物尸体物种丰富的定殖者，并且对腐肉分解这一重要的生态系统服务有贡献。揭示改变与腐肉相关的隐翅虫群落的人为和环境驱动因素，应能增进我们对尸体腐烂可塑性的理解。我们报告了在德国三个地理区域内具有不同管理强度梯度的森林地点，65具正在腐烂的仔猪尸体上存在80种隐翅虫。揭示了影响甲虫丰度、多样性和群落组成的局部和景观驱动因素。森林管理和区域影响隐翅虫的丰度，而多样性受局部栖息地参数（土壤pH值、凋落物覆盖）和区域的影响。随着管理强度的增加，隐翅虫的群落组成通过促进广适性物种而发生变化。就单一物种而言，[此处原文缺失两种物种名称]与未管理的森林相关，[此处原文缺失一种物种名称]与高度利用的林分相关。所提供的关于德国森林中与腐肉相关的隐翅虫群落的空间信息不仅具有腐肉生态学意义，而且具有法医昆虫学意义。
