“…For more details see Theorem 3.1 in [19]. At the same time, we also see that the dynamical properties for many special cases of systems (1) and (2) have been extensively studied, for example [1,5,20,21,2,3,22,6,7,[23][24][25][26][27][28][29][30][31][32][33]8,[34][35][36] and the references cited therein. The main study subjects are the permanence, persistence and extinction of species, the local and global asymptotic stability of systems, the existence and uniqueness of positive periodic solution and almost periodic solution, and the bifurcation and dynamical complexity, etc.…”
