Effects of Biological Invasions on Structure of Assembled Networks
Non-assembled network and assembled network are two commonly used networks in studies of community ecology.In this paper,we established a trait-based dynamic food web model,constructing two types of networks based on the same species pool.Then,we compared the frequency distribution of persistent species traits and dominant species traits in stable community of the both networks,and explored the influence of community assembly on species coexistence and network structure.The results showed that saturated networks formed by community assembly were different from stable network without community assembly,and the distribution of persistent species traits and degrees in assembled network is more regular than that in the non-assembled network.
