Study on interaction of the marine food web based on complex network theory

The relationship between marine lives is manifested by certain aspects of the marine food chain, which are composed of a number of tropic structures. And the marine food web consists of number of intricate interlacing food chain. Because of its complexity, traditional quantitative theory is not efficient, even if the qualitative analysis is also difficult to figure out. The emergence of complex network theory will provide a more convenient and effective way for the marine food web. In this study, the relationship among species from plankton to aquatic birds food web will be studied based on complex network theory. The impact of distinction of one or more key species on the marine food web was probed. It will provide the scientific basis for the fishing system, which will be beneficial to the sustainable development of coastal ecosystems, reasonable and responsible fisheries management.
