摘要:
基于2011 年春季的生态调查资料, 报道了江苏小庙洪自然潮间带牡蛎礁大型底栖动物的多样性及其群落结构。通过16S rDNA基因序列分析发现, 在小庙洪牡蛎礁内分布有3种牡蛎(熊本牡蛎Crassostrea sikamea、近江牡蛎C. ariakensis和密鳞牡蛎Ostrea denselamellosa), 其中分布于潮间带区的造礁活体牡蛎为熊本牡蛎, 其平均密度和生物量分别为(2199±363)ind/m2 和(12361± 1645)g/m2。在该牡蛎礁内记录到定居性大型底栖动物(不包括3种牡蛎)共计43科66种, 礁体大型底栖动物的总栖息密度和生物量分别达到(2830±182)ind/m2 和(499.59±35.41)g/m2, 显著高于邻近的软相潮间带泥(沙)质滩涂[密度(102±29)ind/m2; 生物量(53.10±22.80)g/m2]和潮下带泥滩[密度(140± 60)ind/m2; 生物量(43.23±22.37)g/m2] (P<0.001)。

Abstract:
Based on the ecological monitoring data in the spring of 2011, the study firstly determined the biodiversity and community structure of resident benthic macroinvertebrates on a natural and intertidal oyster reef located in Jiangsu Province, China. Three oyster species, kumamoto oyster (Crassostrea sikamea), Suminoe oyster (Crassostrea ariakensis) and Asian Milin oyster (Ostrea denselamellosa), were identified to coexist on the intertidal reef based on 16S rDNA gene sequence analysis. The kumamoto oyster was the only species that formed the complex, three-dimensional reef structure in the intertidal zone. The mean abundance and biomass of the oyster were (2199±363)ind/m2 and (12361±1645)g/m2, respectively. A total of 66 resident benthic macroinvertebrate species (exclusive of three oyster species) were recorded on the natural reef, representing 6 phyla and 43 families and holding the mean density of (2830±182)ind/m2 and the mean biomass of (499.59±35.41)g/m2. Density and biomass of resident benthic macroinvertebrates were significantly higher on the natural oyster reef than over the intertidal [density (102±29)ind/m2; biomass (53.10±22.80)g/m2] or subtidal [density (140±60)ind/m2; biomass (43.23±22.37)g/m2] mudflat (P<0.001).
