As coral reef communities change and reorganise in response to anthropogenic and climate disturbances, there is a growing need of detecting and understanding the different emerging species regimes and their contribution to key ecosystem processes. Using a case study on coral reefs at the epicentre of tropical marine biodiversity (North Sulawesi), we explored how application of different biodiversity approaches (i.e. use of major taxonomic categories, high taxonomic resolution categories and trait-based approaches) affects the detection of distinct fish and benthic community assemblages. Our results show that using major categories (family level or above) to study coral reef communities fails to identify distinct regimes. We also show that for detection of different benthic regimes, especially communities dominated by non-coral organisms, monitoring of only scleractinian coral communities is insufficient, and that all types of benthic organisms (e.g. sponges, ascidians, soft corals, algae etc.) need to be considered. We have implemented for the first time, the use of a trait-based approach to study the functional diversity of whole coral reef benthic assemblages, which allowed us to detect five different community regimes, only one of which was dominated by scleractinian corals. We circumvented the challenge that for some benthic groups (e.g. sponges, ascidians or some soft corals) visual identification up to the species level is not possible, by identifying and categorising traits that can be applied to groups of similar organisms instead of specific species. Furthermore, by the parallel study of benthic and fish communities we provide new insights into key processes and functions that might dominate or be compromised in the different community regimes.

超越珊瑚藻制度：高分类学分辨率调查和基于特征的分析揭示了多种底栖生物制度

随着珊瑚礁群落因人为和气候干扰而发生变化和重组，对检测和了解不同的新兴物种制度及其对关键生态系统过程的贡献的需求日益增长。通过对热带海洋生物多样性（北苏拉威西省）震中珊瑚礁的案例研究，我们探讨了不同生物多样性方法的应用（即主要分类学类别，高分类学分辨率类别和基于特征的方法的使用）如何影响对不同生物多样性的检测。鱼和底栖动物群落。我们的结果表明，使用主要类别（家庭级别或更高级别）来研究珊瑚礁群落无法识别不同的制度。我们还表明，为了检测不同的底栖生物，特别是非珊瑚生物为主的社区，仅监测巩膜珊瑚群落是不够的，需要考虑所有类型的底栖生物（例如海绵，海鞘，软珊瑚，藻类等）。我们首次使用基于特征的方法来研究整个珊瑚礁底栖生物群的功能多样性，这使我们能够发现五个不同的群落制度，其中只有一个是巩膜珊瑚。我们避免了以下挑战：对于某些底栖动物群体（例如海绵，海鞘或某些软珊瑚），无法通过识别和分类可应用于相似生物组而不是特定物种的特征来进行物种识别。此外，
