| Sumario: | Undaria pinnatifidais an Asian seaweed that is valuable as anedible species. This kelp was first reported for Spain in the 1980son Galician coasts, where it is now widely distributed and incor-porated into the native community. In Galicia, intertidal popula-tions of the sporophytic phase typically inhabit sites under mod-erate wave-exposure in the early spring, albeit they can be foundthroughout the year as the species displays at least two recruit-ment periods per year. The morphology varies between individ-uals and depends strongly on the spatiotemporal pattern of en-vironmental conditions. The chronology of the introduction ofthis species and the types of habitat where it is currently inte-grated on Galician coasts clearly reveal that the presence and lo-cal expansion of this kelp is influenced largely by human activi-ties, mainly shellfish aquaculture and maritime traffic. U. pinna-tifidahas a slow natural expansion, limited aggressiveness and ittemporarily fills empty niches; this kelp displays luxuriant growthonly on artificial substrates or in otherwise disturbed communi-ties. |
