Abstract

This paper is devoted to the study of the propagation dynamics of a mutualistic model of mistletoes and birds with nonlocal dispersal. By applying the theory of asymptotic speeds of spread and travelling waves for monotone semiflows, we establish the existence of the asymptotic spreading speed

$c^*$

, the existence of travelling wavefronts with the wave speed

$c\ge c^*$

and the nonexistence of travelling wavefronts with

$c\lt c^*$

. It turns out that the spreading speed coincides with the minimal wave speed of travelling wavefronts. Moreover, some lower and upper bound estimates of the spreading speed

$c^*$

are provided.

具有非局部扩散的槲寄生与鸟类共生模式的繁殖动力学

本文研究了具有非局部扩散的槲寄生与鸟类共生模式的繁殖动力学。利用单调半流的传播波和行波的渐近速度理论，证明了其渐近传播速度$c^*$的存在性，波速$c\ \ c^*$的行波前的存在性和行波前$c\lt c^*$的不存在性。结果表明，传播速度与行波前的最小波速一致。此外，给出了扩展速度$c^*$的下界和上界估计。
