Macrozoobenthos living around several pipelines placed at different depths and sediment types in the Western Adriatic Sea was investigated for three years after structures' deployment to detect possible effects due to their installation and presence. Three environmental habitats were considered based on the grain size (silty clay, clayey silt and sand). Samplings were taken within a radius of 100 m from the pipelines and at control sites. Multivariate and univariate analysis showed peculiarities of the three habitats due to the different sediment type, without differences between pipelines and controls inside each group. Silty clay and clayey silt communities appeared quite similar, being mainly represented by opportunistic species typical of the Adriatic coastal area. Benthic populations found at the offshore relict sand were characterized by a higher percentage of sensitive species. Independently of sediment typology, pipelines' installation seems to not affect the benthic populations that appear more influenced by environmental features.
研究了在亚得里亚海西部，不同深度和沉积物类型的几个管道周围的大型底栖动物，这些管道在安装后的三年内进行了调查，以检测其安装和存在可能产生的影响。根据粒度（粉质粘土、粉质淤泥和沙子），考虑了三种环境生境。在离管道半径 100 米范围内和对照点进行了采样。多元和单变量分析显示，由于不同的沉积物类型，三种生境具有特殊性，而每组内的管道和对照之间没有差异。粉质粘土和粉质淤泥群落非常相似，主要由亚得里亚海沿海地区特有的机会主义物种组成。在近海遗留沙地上发现的底栖种群的特征是敏感物种的比例较高。无论沉积物类型如何，管道的安装似乎都不会影响底栖种群，这些种群似乎更多地受到环境特征的影响。
