Thanks to several European directives and conventions there is a general increase of awareness regarding the key ecological role of coralligenous habitats in the Mediterranean Sea, addressing several research projects to standardize protocols for the description of its integrity. Here we surveyed 13 stations along the Italian coasts of the Western Mediterranean Sea, using video-transects technique, comparing the biological structure of coralligenous assemblages and testing the importance of their three-dimensional complexity as a proxy to define their health conditions. We considered the diversity of taxa, fishing impacts and the entity of damage on gorgonian's choenenchyme due to thermal stress, to evidence a gradient in the coralligenous health conditions. Here we developed a method to evaluate coralligenous complexity, selecting categories of taxa particularly sensitive to multiple stressors, named Structural Descriptors to describe the three-dimensional structure of the bioconcretions and to assess a unique Index of 3D - Structural Complexity.
由于几项欧洲指令和公约的要求，人们对珊瑚礁生境在地中海中的关键生态作用的认识普遍提高，这促使人们开展了多项研究项目，以制定标准化的方案来描述其完整性。在这里，我们使用视频横切技术调查了地中海西部意大利沿海的 13 个站点，比较了珊瑚礁生物群落的生物结构，并测试了其三维复杂性作为健康状况的替代指标的重要性。我们考虑了分类多样性、捕捞影响以及热应激对柳珊瑚软珊瑚组织的损害程度，以证明珊瑚礁健康状况存在梯度。在这里，我们开发了一种评估珊瑚礁复杂性的方法，选择了对多种胁迫因素特别敏感的分类群类别，命名为结构描述符，用于描述生物凝块的三维结构，并评估独特的三维结构复杂性指数。
