We investigated the validity of Autonomous Reef Monitoring Structures (ARMS) as monitoring tools for hard bottoms across a wide geographic and environmental range. We deployed 36 ARMS in the northeast Atlantic, northwest Mediterranean, Adriatic and Red Sea at 7-17 m depth. After 12-16 months, community composition was inferred from photographs, in six plate-faces for each ARMS. Overall, we found a highly significant effect of sea region, site (within seas), and plate-face on community composition. Plate-faces thus represent distinct micro-habitats and provide pseudo-replicates, increasing statistical power. Within each sea region taken individually, there was also a highly significant effect of site and plate-face. Because strong effects were obtained despite the fusion of taxonomic categories at high taxonomic ranks (to ensure comparability among biogeographic provinces), ARMS photo-analysis appears a promising monitoring tool for each sea region. We recommend keeping three ARMS per site and analyzing more numerous sites within a sea region to investigate environmental effects.
我们调查了自主式珊瑚礁监测浮标（ARMS）作为监测广泛地理和环境范围内硬底生境的工具的有效性。我们在东北大西洋、西北地中海、亚得里亚海和红海的 7-17 米深处部署了 36 个 ARMS。12-16 个月后，从每个 ARMS 的六个板块上的照片推断群落组成。总体而言，我们发现海地区域、站点（在海域内）和板块面在群落组成上有高度显著的影响。板块因此代表了独特的小生境，并提供了伪重复，从而增加了统计能力。在每个单独考虑的海域中，站点和板块面也有高度显著的影响。由于尽管在高分类等级上融合了分类类别（以确保生物地理省份之间的可比性），但仍获得了强烈的影响，因此 ARMS 照片分析似乎是每个海域的一种有前途的监测工具。我们建议每个站点保留三个 ARMS，并在一个海域内分析更多的站点，以调查环境影响。
