This study examined the potential use of macroalgae epiphytic on mangrove aerial roots as indicators of estuarine contamination. The distribution and abundance of macroalgae was investigated in four estuaries in the vicinity of Sydney, Australia, and compared to water and sediment metal concentrations, nutrient concentrations and physicochemical parameters over four seasonal surveys. Macroalgal diversity and distribution appeared to be highly influenced by the ambient contaminant concentrations, while biomass appeared to be linked with nutrient concentrations. The distribution of the Rhodophyta species, Catenella nipae Zanardini significantly decreased as metal concentrations increased among the estuaries during all seasonal surveys. This species showed strong potential for use as a bioindicator of estuarine contamination.
本研究考察了附着在红树林气生根上的大型藻类作为河口污染指标的潜在用途。在澳大利亚悉尼附近的四个河口对大型藻类的分布和丰度进行了调查，并在四个季节调查中与水和沉积物中的金属浓度、养分浓度及理化参数进行了比较。大型藻类的多样性和分布似乎受周围污染物浓度的高度影响，而生物量似乎与养分浓度有关。在所有季节调查中，随着河口金属浓度的增加，红藻门物种尼帕链藻（Catenella nipae Zanardini）的分布显著减少。该物种显示出作为河口污染生物指标的强大潜力。
