In this paper, we are mainly concerned with the effect of nonlocal diffusion and dispersal spread on bifurcations of a general activator-inhibitor system in which the activator has a nonlocal dispersal. We find that spatially inhomogeneous patterns always exist if the dispersal rate of the activator is sufficiently small, while a larger dispersal spread and an increase of the activator diffusion inhibit the formation of spatial patterns. Compared with the "spatial averaging" nonlocal dispersal model, our model admits a larger parameter region supporting pattern formations, which is also true if compared with the local reaction-diffusion one when the dispersal spread is small. We also study the existence of nonconstant positive steady states through bifurcation theory and find that there could exist finite or infinite steady state bifurcation points of the inhibitor diffusion constant. As an example of our results, we study a water-biomass model with nonlocal dispersal of plants and show that the water and plant distributions could be inphase and antiphase.

Figure 5. $ (a) $ Turing instability region of the classical reaction-diffusion model. $ (b) $ Turing instability region of the "spatial averaging" nonlocal dispersal model when the inhibitor has a nonlocal dispersal. $ (c) $ Turing instability region of the nonlocal model when the inhibitor has a nonlocal dispersal with the kernel function (1.5). Here, the constant equilibrium solution is stable in region "S" and the spatial scale could induce instability in region "U"
