Coastal marine waters — macrozoobenthos data (years 2008-2017)

The surveys concern the study of the macrozoobentonic communities of the mobile funds (sand and/or mud) that characterise the seabed and transition environments of Veneto. The populations present are continuously exposed both to factors that support their development (e.g. solar radiation, nutrients) and to factors that can cause an alteration (e.g. physicochemical variations in water, presence of pollutants, dredging). The study of the composition and structure (through the calculation of indices) of the benthic communities of mobile funds are used to evaluate possible changes and identify any alterations in the area studied.本调查围绕威尼托地区海底与过渡环境的典型底质——流动底质（沙质和/或泥质）中的大型底栖动物群落（macrozoobenthic communities）展开研究。该区域内现存的底栖动物群落始终同时受到两类因素的影响：一类是支撑其生长发育的正向因子（如太阳辐射、营养盐），另一类是可能引发群落结构改变的扰动因子（如水体理化性质变化、污染物存在、疏浚作业）。通过计算相关群落指数，对流动底质底栖生物群落的组成与结构进行分析，可用于评估研究区域内可能出现的群落变化，并识别各类潜在的群落扰动。
