Abstract. The dispersal ability of seeds, spores, and larvae can greatly influence spatial heterogeneity in the abundance of plants and sedentary animals, especially after a severe and widespread disturbance has caused extensive population declines and opened large areas for colonization by propagules. However, little work has been done on the relationship between propagule dispersal and spatial heterogeneity in species abundance. We hypothesize that, shortly after a disturbance, spatial variability in abundance of sedentary organisms is negatively ...
