In　this　paper,　a　nonlinear　nonautonomous　predator-prey　model　with　diffusion　and　continuous　distributed　delay　is　studied,　where　all　the　parameters　are　time-dependent.　The　system,　which　is　composed　of　two　patches,　has　two　species:　the　prey　can　diffuse　between　two　patches,　but　the　predator　is　confined　to　one　patch.　We　first　discuss　the　uniform　persistence　and　global　asymptotic　stability　of　the　model;　after　that,　by　constructing　a　suitable　Lyapunov　functional,　some　sufficient　conditions　for　the　existence　of　a　unique　almost　periodic　solution　of　the　system　are　obtained.　An　example　shows　the　feasibility　of　our　main　results.　(c)　2004　Elsevier　B.V.　All　rights　reserved.
