沿海地区的城市化和蓝色经济的增长推动了海洋环境中人工结构的扩散。这些结构支持不同的生态群落相比，天然的硬基板，潜在地反映了它们的构造材料的差异。我们对46项研究进行了荟萃分析，以比较不同材料类型（天然或生态友好型与人工）对建筑结构上殖民生物群的影响。无论是丰富的殖民者还是丰富的殖民者都没有表现出一致的人工和天然基质之间或生态友好型和标准混凝土之间的差异模式。相反，人工和天然材料之间的生物丰度（但不是丰富度）存在差异，根据材料类型和功能组而变化。与生物源材料和岩石相比，聚合物和金属支持的底栖物种总数（在对固着物种和移动的物种一起进行评估的研究中）、固着无脊椎动物和珊瑚（在对这些群体进行单独评估的研究中）的丰度明显较低。相比之下，非本地物种在木材上的数量要比金属上多得多。与木材相比，混凝土支持更大丰度的一般社区，包括栖息地形成物种。我们的研究结果表明，生物群落的生态要求，以及经济，物流和工程因素，应考虑在材料选择的多功能海洋结构，提供工程和生态（提高丰度和多样性）的好处。
Urbanisation of coastal areas and growth in the blue economy drive the proliferation of artificial structures in marine environments. These structures support distinct ecological communities compared to natural hard substrates, potentially reflecting differences in the materials from which they are constructed. We undertook a meta-analysis of 46 studies to compare the effects of different material types (natural or eco-friendly vs. artificial) on the colonising biota on built structures. Neither the abundance nor richness of colonists displayed consistent patterns of difference between artificial and natural substrates or between eco-friendly and standard concrete. Instead, there were differences in the abundance of organisms (but not richness) between artificial and natural materials, that varied according to material type and by functional group. When compared to biogenic materials and rock, polymer and metal supported significantly lower abundances of total benthic species (in studies assessing sessile and mobile species together), sessile invertebrates and corals (in studies assessing these groups individually). In contrast, non-indigenous species were significantly more abundant on wood than metal. Concrete supported greater abundances of the general community, including habitat-forming species, compared to wood. Our results suggest that the ecological requirements of the biological community, alongside economic, logistic and engineering factors should be considered in material selection for multifunctional marine structures that deliver both engineering and ecological (enhanced abundance and diversity) benefits.
