Abstract:
The seabed desertification has increasingly highlighted the importance of benthic habitat restoration. Strategically engineered artificial reefs emerges as pivotal in achieving restoration objectives. However, the significant influence of foundation species on biotic components and ecosystem attributes within diverse artificial reefs has been underrecognized. This study collated twenty Ecopath models of artificial reefs and their corresponding natural control ecosystems along the coasts of the Yellow Sea and Bohai Sea, China, categorizing them into five distinct system types predicated on the biomass and productivity of foundational species. Our results suggest that dimensionless indices, rather than actual system values, were posited to facilitate inter-comparative analysis. The comparative analysis revealed differences in biomass distribution, energy utilization, and trophic structure across the five ecosystem types. All the artificial reef systems collectively enhanced the utilization of primary production. Foundation species components formed the cornerstone of system functionality, significantly impacting ecosystem stability through modulation of energy flow dynamics. Distinct impacts were observed from shellfish and macroalgae; the former augmenting the detrital food chain, while the latter bolstering the grazing food chain. Consequently, the model-based integrated analysis enabled a robust comparison among various types of artificial reef ecosystems and confirmed that promoting the colonization of foundation species was a non-negligible factor in the design and deployment of artificial reefs.
摘要:
海底荒漠化日益凸显了海底栖息地恢复的重要性。战略工程人工鱼礁在实现恢复目标方面至关重要。然而,尚未认识到基础物种对不同人工鱼礁中生物成分和生态系统属性的重大影响。本研究整理了黄渤海沿岸人工鱼礁及其相应的自然控制生态系统的20个Ecopath模型,中国,根据基础物种的生物量和生产力,将它们分为五种不同的系统类型。我们的结果表明,无量纲指数,而不是实际的系统值,被认为是为了促进相互比较分析。比较分析揭示了生物量分布的差异,能源利用,以及五种生态系统类型的营养结构。所有人工鱼礁系统共同提高了初级生产的利用率。基础物种组件构成了系统功能的基石,通过调节能量流动力学显著影响生态系统的稳定性。观察到贝类和大型藻类的不同影响;前者增加了碎屑食物链,而后者加强了放牧的食物链。因此,基于模型的综合分析能够对不同类型的人工鱼礁生态系统进行稳健比较,并证实促进基础物种的定殖是人工鱼礁设计和部署过程中不可忽视的因素.
