| Abstract: | In this paper, the qualitative behavior of solutions of the bobwhite quail pop-ulation modelwhere 0 ＜ a ＜ 1 ＜ a + b,p,c ∈ (0, ∞) and k is a nonnegative integer, is investigated.Some necessary and suficient as well as sufficient conditions for all solutions of the modelto oscillate and some sufficient conditions for all positive solutions of the model to benonoscillatory and the convergence of nonoscillatory solutions are derived. Furthermore,the permanence of every positive solution of the model is also showed. Many known resultsare improved and extended and some new results are obtained for G. Ladas' open problems. |
