Variation in density of early stages, that is, larvae and juveniles, is a major determinant of the
distribution and abundance of the adult population of most marine invertebrates. These early
stages thus play a key role in competitive interactions, and, more specifically, in invasion
dynamics when biologically similar native and non‐native species (NNS) come into contact
in the same habitat. We examined the settlement dynamics and settlement rate of two
important members of the fouling community that are common on human‐made …
