Global asymptotic stability of an almost periodic nonlinear ecological model

►This paper provides an answer to an open problem arising in a recent paper [1]. ►Not only an important restriction of their theorem is removed, but also some other conditions are weakened in this paper. ►The problem is very general. By applying the obtained results to some special cases, many earlier results are significantly improved. ► Several illustrative examples and their simulations are provided to show the effectiveness of the obtained results.
