报告摘要: We propose a structured integro-difference equation model for an invasive marine species with a pelagic larval stage and examine the role of dispersal heterogeniety on the spreading speed.   The spread of the green crab northward along the northwest coast of the Atlantic is used as a case study.  We find that the relationship between spreading speed and demographic and dispersal parameters is similar to the relationship found in Fisher's equation.  We also find that temporal variation in dispersal results in a faster spread rate than predicted by a time-averaged dispersal kernel. This is joint work with Lin Wang, Myriam Barbeau and Ali Gharouni.
