报告摘要：In this talk, we discuss the evolution dynamics for an impulsive hybrid population model with nonlocal dispersal/random diffusion operators in a heterogeneous landscape. Since this hybrid model generates a time-periodic semiflow on the space of continuous functions, the problem reduces to the investigation of a discrete-time recursion system defined by the Poincare period map. We obtain a threshold-type result on the global dynamics of the population in a single-patch landscape. Moreover, the recursion admits a unique positive steady state which is globally asymptotically stable. For the population spread in a periodic-patchy landscape, we establish the existence of spreading speed and its coincidence with the minimal wave speed for spatially periodic traveling waves. Simulations are presented to illustrate our analytic results.
