- Carrion is long recognized as important to scavengers. How carrion may affect soil microbial biodiversity and ecosystem processes in natural systems is comparatively unknown, but is important for the intersection of vertebrate food webs, below‐ground processes and ecological heterogeneity.
- We assessed in situ soil and plant responses to wolf‐killed mammal carrion in Yellowstone National Park, USA.
- Bison and elk carcasses increased soil respiration and vegetation nutrient concentration and the carcasses contain altered bacterial and fungal communities compared to control plots. The ‘fingerprints’ of soil microbial taxa associated with bison compared to elk carcasses differed considerably and taxa are found dependent upon abiotic gradients and soil properties.
- We found evidence that soil microbial community changes associated with carcasses may not be as generalizable as previously thought, which is important for a mechanistic understanding of the links between carrion and soil heterogeneity and potentially for applications in forensic science.
- This work demonstrates the importance of carrion studies in natural systems. Our findings show that carrion creates distinct ecological patterns that contribute to both above‐ and below‐ground biological heterogeneity, linking carrion distribution dynamics with soil microbial biodiversity and ecosystem functions.

麋鹿和野牛尸体对美国黄石公园土壤微生物群落和生态系统功能的影响
- 腐肉长期以来被认为对清道夫很重要。腐肉如何影响自然系统中的土壤微生物多样性和生态系统过程尚不清楚，但对于脊椎动物食物网，地下过程和生态异质性的交叉点很重要。
- 我们在美国黄石国家公园评估了土壤和植物对狼杀死的哺乳动物腐肉的原位反应。
- 野牛和麋鹿的尸体与对照样地相比，增加了土壤呼吸和植被养分含量，并且尸体的细菌和真菌群落发生了变化。与麋鹿尸体相比，与野牛相关的土壤微生物分类单元的“指纹”差异很大，并且发现分类单元取决于非生物梯度和土壤特性。
- 我们发现有证据表明，与尸体相关的土壤微生物群落变化可能不像以前认为的那样普遍化，这对于机械理解腐肉和土壤异质性之间的联系以及潜在地在法医学中的应用至关重要。
- 这项工作证明了腐肉研究在自然系统中的重要性。我们的发现表明，腐肉产生了独特的生态模式，有助于地上和地下生物异质性，并将腐肉分布动态与土壤微生物生物多样性和生态系统功能联系起来。
