WK 4 - Demography and dispersal: The analysis of invasion wave speeds
The spread of an invasive species is determined by its demography and its patterns of dispersal. Demography describes how individual organisms “move,” by development, through their life cycle. Studies of dispersal focus on how individuals “move,” via passive or active transport, through space. Recent developments make it possible to combine demography and dispersal into a single model incorporating both kinds of “movement.” In these models --- integrodifference matrix population models --- both development and dispersal can be stage-dependent. The models project the speed with which a population will invade an unoccupied space. This workshop will present an introduction to these models and the methods used to analyze them. Topics to be covered: 1) computing the invasion speed from demographic and dispersal data; 2) sensitivity and elasticity analysis of the invasion speed; and 3) LTRE analysis of the response of invasion speed to variation in dispersal and demography.
