报告摘要:  In this talk, we study a predator-prey reaction-diffusion model with seasonality and fear effect. In this model, the predator species reproduces only at a certain time of each year. We calculate the steady states of the system and study their stabilities, then we derive the conditions for Turing instability to occur. Numerical simulations show that (i) spatial patterns can emerge for Beddington-DeAngelis functional response; (ii) the system can have oscillatory behavior for both linear functional response and Beddington-DeAngelis functional response.
