分解通过促进养分循环、能量流动和限制生物量积累而有助于全球生态系统功能。影响这一过程的分解有机体形成了多样、复杂和高度动态的群落，这些群落通常专门针对不同的植物或动物资源。尽管发挥着相同的净作用，但仍需要在概念上综合有关死亡植物和动物资源范围内分解者群落结构和功能的信息。缺乏综合性限制了生态系统和社区生态学重要领域的跨学科学习和研究。在这里，我们阐述了“necrobiome”的概念，并制定了一个框架，描述分解者社区和他们的相互作用与植物和动物资源类型在多个生态系统。我们概述了生物结构和生态功能的坏死，沿着如何坏死适应更广泛的景观和生态系统的背景。扩大的necrobiome模型提供了一套跨资源类型的分解者社区的观点，并在概念上将植物和动物分解者社区统一到同一个框架中，同时承认过程和机制的关键差异。该框架旨在提高研究人员的认识，并推进明确的，机械的假设，进一步了解分解者社区对生物多样性，生态系统的结构和功能，全球养分循环和能量流动的贡献的建设。
Decomposition contributes to global ecosystem function by contributing to nutrient recycling, energy flow, and limiting biomass accumulation. The decomposer organisms influencing this process form diverse, complex, and highly dynamic communities that often specialize on different plant or animal resources. Despite performing the same net role, there is a need to conceptually synthesize information on the structure and function of decomposer communities across the spectrum of dead plant and animal resources. A lack of synthesis has limited cross-disciplinary learning and research in important areas of ecosystem and community ecology. Here we expound on the "necrobiome" concept and develop a framework describing the decomposer communities and their interactions associated with plant and animal resource types within multiple ecosystems. We outline the biotic structure and ecological functions of the necrobiome, along with how the necrobiome fits into a broader landscape and ecosystem context. The expanded necrobiome model provides a set of perspectives on decomposer communities across resource types, and conceptually unifies plant and animal decomposer communities into the same framework, while acknowledging key differences in processes and mechanisms. This framework is intended to raise awareness among researchers, and advance the construction of explicit, mechanistic hypotheses that further our understanding of decomposer community contributions to biodiversity, the structure and function of ecosystems, global nutrient recycling and energy flow.
