AbstractTo understand the nutrient relationship, food web structure, and their seasonal changes in major benthic communities in Yangma Island, Yantai, Shandong, samples of macrobenthos, sediment particles(SOM), suspended organic matter(POM), phytoplankton, and zooplankton were collected in the intertidal zone of the island in spring(March) and summer(July) 2019. Stable isotopes of carbon and nitrogen in the macrobenthos were measured and analyzed. Results show that the δ13 C and δ15 N values of macrobenthos were ?20.23‰— ?12.99‰, 5.32‰—10.45‰ in spring and ?21.91‰— ?9.88‰, 7.01‰—14.17‰ in summer, respectively. The stable isotopes values were greater in summer than those in spring, and the values of the same macrobenthos species changed seasonally. The trophic level of major macrobenthos species in spring and summer was 1.98—3.49 and 1.89—4.00, respectively. The nutrient levels of the same macrobenthos in two seasons showed no significant change(P>0.05). The nutrition delivery sequence from low to high was filter feeding mollusk → polychaete → crustacean, which was consistent with the direction of energy flow.
Other Abstract为探明烟台潮间带主要底栖生物类群间的营养关系和食物网结构特征及其季节性变化,于2019年春季(3月)和夏季(7月)在山东烟台养马岛潮间带采集大型底栖动物、沉积颗粒(SOM)、悬浮有机质(POM)、浮游植物和浮游动物样品。利用稳定同位素技术,对养马岛海滩潮间带底栖生物的碳、氮稳定同位素进行测定和分析。结果表明:大型底栖动物在春季和夏季δ13C和δ15N值分别为?20.23‰—?12.99‰, 5.32‰—10.45‰和?21.91‰—?9.88‰, 7.01‰—14.17‰。夏季的碳、氮稳定同位素数值范围相较于春季均有所增加,相同大型底栖动物物种的碳、氮稳定同位素值会随季节变化而发生变化。春季该潮间带主要大型底栖动物的营养级范围为1.98—3.49,夏季为1.89—4.00。相同大型底栖动物营养级在季节之间无显著变化(P>0.05)。营养传递顺序可表达为:滤食性软体动物→多毛类→甲壳动物,与能量流动方向一致。
