“…Since 1970, U. pinnatifida has become widely established in temperate coastal areas, including the coasts of France, England, Argentina, New Zealand, and Argentina (Perez et al 1981, Hay 1990, Fletcher & Manfredi 1995, Casas & Piriz 1996, Campbell & Burridge 1998. Like native U. pinnatifida populations, most invasive populations follow a seasonal cycle and have discrete annual generations (Floc'h et al 1996, Campbell & Burridge 1998; however, some New Zealand populations exhibit overlapping generations and sporophytes can be found year-round (Hay & Villouta 1993). In these populations, U. pinnatifida competes with native macroalgal assemblages throughout the year, making its impact potentially more severe.…”

We combined field monitoring and laboratory experiments to examine the population ecology of both the microscopic and macroscopic stages of a new invasion of Undaria pinnatifida in California. Over the course of 1 yr, we observed 2 distinct recruitment pulses of individuals in the Santa Barbara harbor; the appearance of these pulses was strongly correlated with a 4°C drop in ocean temperature approximately 2 mo prior to recruitment. Cultures of zoospores and successive microscopic stages revealed thermal tolerances consistent with field recruitment data; individuals grown at 13°C had significantly higher survivorship than individuals grown at higher temperatures (harbor temperatures annually ranged from 12 to 21°C). The 2 cohorts also differed greatly in individual size, growth rate, and survival to maturity. Grazing by herbivores, predominately the native kelp crab Pugettia producta, effectively prevented nearly all individuals in the second cohort from reaching reproductive maturity. Grazer control was effective despite far higher rates of recruitment during the second recruitment pulse. Our results highlight the potential for extreme variability in U. pinnatifida demography mediated by local oceanographic and biotic factors. Understanding controls on U. pinnatifida demography helps to explain variation in the spread and impact of this invader worldwide, and allows better prediction of when and where U. pinnatifida may continue its invasion along the west coast of North America.

“…The effect of human activities in modifying organic matter dynamics in the coastal areas of Japan is thus clearly evident. As reviewed by Campbell & Burridge (1998), U. pinnatifida, originally native to the temperate coasts of Japan, Korea and China, has extensively invaded several coastal inlets of the north and south Pacific. The spread of this macroalga may lead to conditions similar to those we observed in Otsuchi Bay.…”

“…Es muy frecuente que los cascos de las embarcaciones lleven adheridos esporófitos que pueden liberar esporas en otros lugares (Campbell & Burridge, 1998). Este último sistema provocó la introducción de esta especie en algunas localidades de las Islas Británicas a través de pequeños barcos de recreo procedentes de St. Malo, localidad de la Bretaña Francesa donde estaba siendo sometida a explotación industrial mediante cultivo en el mar (Fletcher & Manfredi, 1995); o en Asturias, donde barcos de recreo procedentes de Francia con gametófitos adheridos a los cascos pasan el invierno y primavera en puertos españoles (Salinas & al., 1996).…”

ResumenUndaria pinnatifida es una especie asiática de gran interés económico como alga alimentaria que en la década de los ochenta apareció por primera vez en España en las costas de Galicia, donde actualmente se encuentra ampliamente distribuida y naturalizada. Las poblaciones intermareales de los esporófitos de esta especie en la costa gallega son propias de localidades moderadamente expuestas a la acción del oleaje, siendo muy notorias a principios de primavera; aunque pueden encontrarse casi todo el año, al existir al menos dos períodos anuales de reclutamiento. La morfología de los ejemplares que las forman es muy variable y está fuertemente relacionada con las variaciones espaciotemporales de las condiciones ambientales. Analizando la cronología de su introducción en Galicia y los hábitats y tipos de comunidades en las que se integra, se observa claramente la influencia de las actividades humanas en todo ello, sobre todo las derivadas de la acuicultura de moluscos y el tráfico marítimo. U. pinnatifida es una especie de lenta expansión natural, poco agresiva y que ocupa temporalmente nichos ecológicos vacíos, siendo solo abundante sobre sustratos artificiales o en aquellos naturales cuya vegetación ha sido en alguna medida previamente degradada.Palabras clave: Atlántico noroeste, algas marinas, especies alóctonas, Undaria pinnatifida, morfología, fenología, ecología, impacto ambiental. AbstractUndaria pinnatifida is an Asian seaweed that is valuable as an edible species. This kelp was first reported for Spain in the 1980s on Galician coasts, where it is now widely distributed and incorporated into the native community. In Galicia, intertidal populations of the sporophytic phase typically inhabit sites under moderate wave-exposure in the early spring, albeit they can be found throughout the year as the species displays at least two recruitment periods per year. The morphology varies between individuals and depends strongly on the spatiotemporal pattern of environmental conditions. The chronology of the introduction of this species and the types of habitat where it is currently integrated on Galician coasts clearly reveal that the presence and local expansion of this kelp is influenced largely by human activities, mainly shellfish aquaculture and maritime traffic. U. pinnatifida has a slow natural expansion, limited aggressiveness and it temporarily fills empty niches; this kelp displays luxuriant growth only on artificial substrates or in otherwise disturbed communities.
