| الوصف: | Dispersal and fecundity are two fundamental traits underlying the spread of populations. Using integral difference equation models, we examine how individual variation in these fundamental traits and the heritability of these traits influence rates of spatial spread of populations along a one-dimensional transect. Using a mixture of analytic and numerical methods, we show that individual variation in dispersal rates increases spread rates and the more heritable this variation, the greater the increase. In contrast, individual variation in lifetime fecundity only increases spread rates when some of this variation is heritable. The highest increases in spread rates occur when variation in dispersal positively co-varies with fecundity. Our results highlight the importance of estimating individual variation in dispersal rates, dispersal syndromes in which fecundity and dispersal co-vary positively and heritability of these traits to predict population rates of spatial spread. Dispersal and fecundity are two fundamental traits underlying the spread of populations. Using mathematical models, we examine how individual variation in these traits and their heritability influence rates of spatial spread of populations. We show that individual variation in dispersal increases spread rates and the more heritable this variation, the greater the increase. The highest increases in spread rates occur when variation in dispersal positively co-varies with fecundity.
