在经典的Pearson-Rosenberg范式框架下讨论了有机质沉积通量与底栖生物群落结构的关系。除了数量外，还强调了有机质质量的重要性。提出了一个研究群落结构与有机通量之间关系的简单模型框架。底栖生物食物网的内部动态特征是高度杂食性（以不同营养水平为食）。这一特征与其他系统中公布的食物网数据形成了对比。据推测，海洋碎屑的高质量（与陆地碎屑相比）是解释这种差异的主要因素。由于理论研究表明杂食性破坏了食物网的稳定性，因此讨论了底栖动物食物网的一些稳定机制。确定了在理论研究和实地比较中可以探索的富有成果的问题和机制。
The relation between organic matter deposition fluxes and benthic community structure is discussed in the framework of the classical Pearson-Rosenberg paradigm. The importance of organic matter quality, in addition to quantity, is stressed. A simple model framework to investigate the relation between community structure and quantity of organic flux is proposed. Internal dynamics of benthic food webs are characterized by a high degree of omnivory (feeding on different trophic levels). This feature is contrasted with published data on food webs in other systems. It is hypothesized that the high quality of marine detritus (compared with terrestrial detritus) is the prime factor explaining the differences. Since theoretical studies suggest that omnivory destabilizes food webs, a number of stabilizing mechanisms in benthic food webs are discussed. Problems and mechanisms that could be explored fruitfully in theoretical studies and field comparisons are identified.
