摘要

合适的定殖材料是海洋恢复计划追求的目标。众所周知,生物炭和生物发酵材料既能提供养分,又能减少陆地生态系统中的污染物和病原体风险。我们在意大利南部切萨雷奥港海洋保护区(水深 20 米)用生物炭(B)和生物发酵剂(F)处理过的混凝土瓦片和混凝土瓦片作为海洋生物定殖的对照组(Ct),测试了这些材料在修复方面的功效。从 2019 年 10 月到 2021 年 9 月,对瓷砖的照片进行了监测。最初,生物炭处理呈现出较高的底栖生物总覆盖率(81.23 ± 2.76,中位数 ± SE),不同于生物发酵处理和对照瓦片(分别为 45.65 ± 5.43 和 47.95 ± 3.69)。处理与时间之间的显著交互作用表明,群落结构的变化与生物发酵剂和对照材料中的多毛类覆盖率从第二次监测开始增加有关。此外,生物发酵剂在瓦片上的水下不稳定性可以解释海洋生物覆盖率与对照瓦片相似的原因。因此,生物炭是一种在海水中具有最佳稳定性的材料,与其他两种材料相比,它能在更短的时间内提高海洋生物的定殖能力。

Benthic Colonization on New Materials for Marine Ecosystem Restoration in Porto Cesareo, Italy
Suitable colonization materials are a pursued target in marine restoration programs. Known for making nutrients available while reducing pollutants and the risk of pathogens in terrestrial ecosystems, Biochar and Bioferment materials of organic origin were tested during a two-year experiment. We tested the efficacy of these materials for restoration purposes through experimental concrete tiles treated with Biochar (B) and Bioferment (F) and tiles made of concrete, which were used as controls (Ct) for the colonization of marine organisms in the marine protected area of Porto Cesareo, Southern Italy (20 m depth). Tiles were monitored for photographs from October 2019 to September 2021. Initially, Biochar treatment presented a higher percentage of total benthic cover (81.23 ± 2.76, median ± SE), differing from Bioferment treatment and control tiles (45.65 ± 5.43 and 47.95 ± 3.69, respectively). Significant interaction between treatments and times suggests changes in community structure related to Polychaeta cover increase in Bioferment and control materials from the second monitoring time. Furthermore, the underwater instability of Bioferment on the tiles could explain the similarity with control tiles in marine organisms’ covers. Hence, Biochar is shown to be a material with optimal stability in seawater, demonstrating greater capacity for marine organisms’ colonization in less time compared to the other two materials.

期刊介绍: Journal of Marine Science and Engineering (JMSE; ISSN 2077-1312) is an international, peer-reviewed open access journal which provides an advanced forum for studies related to marine science and engineering. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
