烟台牟平海洋牧场夏季大型底栖动物群落特征
Characteristics of macrobenthic communities at the Muping marine ranch of Yantai in summer
摘要
Abstract
A survey on the characteristics of macrobenthic communities was carried out at the Muping marine ranch of Yantai during June and August 2015 to clarify the characteristics and factors affecting the macrobenthic communities and to analyze the effects of hypoxia on macrobenthic community characteristics. The PRIMER software package was used to calculate four biodiversity indices and to carry out CLUSTER, MDS ordination analyses, AMBI AZTI's Marine Biotic Index and m-AMBI (multivariate-AMBI) to analyze community structure. A total of 97 macrobenthic species were identified in June, of which the dominant group was polychaetes. The average biomass was 18.02 g/m2, of which crustacean species contributed most. A total of 78 macrobenthic species were identified in August, of which the dominant group was polychaetes. The average biomass was 9.28 g/m2, of which polychaete species con-tributed most. Three biodiversity indices, the richness index, the evenness index, and the Shannon–Wiener index were 3.071 ± 0.773, 2.782 ± 0.778, and 0.622 ± 0.143 in June and 3.192 ± 0.369, 2.730 ± 0.510, and 0.751 ± 0.076 in August. The CLUSTER and MDS analyses showed a significant difference between June and August. Environmental factors, including water depth, water temperature, and turbidity were strongly correlated with the abundance and biomass of the macrobenthic communities. Dissolved oxygen was the main cause of the difference between June and August. The AMBI and M-AMBI analysis showed that the macrobenthic species were mostly tolerant and that the area had suffered a moderate disturbance. The seasonal hypoxic environment at the Muping marine ranch of Yantai in August affected species composition of the macrobenthos.关键词
