Abstract:

以多孔鹿角珊瑚(Acroporamillepora)、鼻形鹿角珊瑚(Acroporanasuta)、鹿角杯形珊瑚(Pocilloporadamicornis)、丛生盔形珊瑚(Galaxeafascicularis)和澄黄滨珊瑚(Poriteslutea)为材料,用不同浓度的灭活大肠杆菌液模拟不同梯度的水体浑浊度,研究了造礁石珊瑚共生虫黄藻对水体浑浊度变化的响应.结果表明,水体浑浊度对造礁石珊瑚共生虫黄藻光合效率和密度均有不同程度影响,且抑制作用随浑浊度的增加而加强;不同种类的造礁石珊瑚共生虫黄藻对水体浑浊度的耐受能力不同,块状的丛生盔形珊瑚和澄黄滨珊瑚的耐受能力较强,枝状的多孔鹿角珊瑚、鼻形鹿角珊瑚和鹿角杯形珊瑚的耐受能力相对较弱.
