Species composition and biodiversity of macrofauna in Xing-hua Bay, Fujian
摘要
Abstract
Species composition, biodiversity distribution pattern, and disturbance status of macrofauna were ana-lyzed by quantitative investigations of macrobenthic community in July–September 2013 and February–April 2014 in Xinghua Bay, Fujian. Dominance index, Shannon–Wiener diversity index, Margalef’s richness index, and Pielou’s evenness index were used to analyze the species composition and biodiversity distribution pattern of mac-rofauna. In total, 132 species of macrofauna were identified in Xinghua Bay, Fujian, consisting of 58 species of polychaetes, 27 species of crustaceans, 33 species of mollusks, and 14 species of other phyla. The most dominant group was Polychaeta in the four cruises, which included Nephtys polybranchia,N. oligobranchia,Mediomastus californiensis, andLumbrineris heteropoda. The average biomass of macrofauna in Xinghua Bay was 311.67 g/m2 and the average density was 39.42 ind/m2. The highest values of average biomass and density were observed in April 2014 (398 ind/m2 and 63.23 g/m2, respectively), while the lowest values were observed in July 2013 (252 ind/m2 and 7.77 g/m2, respectively). The biomass and density of macrofauna at different stations varied significantly in the studied area. The highest density was observed at Station 1 (738 ind/m2) and the lowest at Station 12 (90 ind/m2). The highest biomass was observed at Station 15 (108.17 g/m2) and the lowest at Station 22 (8.72 g/m2). The average values of the three biodiversity indices were 2.81 (Margalef’s richness index), 0.87 (Pielou’s evenness index), and 2.727 (Shannon-Wiener diversity index) and varied in different seasons. The highest values were observed in September 2013 (3.20, 0.93, and 3.12, respectively) and the lowest values in April 2014 (2.09, 0.78, and 2.05, respectively). The pattern of biodiversity indices indicated that the macrofauna communities were under disturbance in Xinghua Bay, Fujian.关键词
