Abstract
[Resumen] Los herbarios son una fuente de información útil para el estudio de la distribución geográfica y los cambios en la distribución de las plantas. En el caso de las especies exóticas invasoras, las variaciones en su área de distribución y ecología se dan en cortos espacios de tiempo, que pueden observarse en los materiales recogidos en los herbarios. Cortaderia selloana(Schult. & Schult.f.) Asch. & Graebn (Poaceae) es una gramínea invasora introducida como ornamental, hoy ampliaente naturalizada por la costa norte, oeste y levante de la península ibérica En este estudio se ha realizado una revisión completa de los pliegos de la especie disponibles en los herbarios públicos ibéricos para conocer la historia de la introducción y expansión. Se recibieron y revisaron un total de 155 pliegos pertenecientes a 21 herbarios, datados desde principios del siglo XX hasta la actualidad. La información recogida en los pliegos no permite describir el proceso completo de introducción y expansión en el territorio estudiado, pero aporta datos sobre la distribución de ejemplares en función de su carácter invasor y sexo a lo largo de las décadas y la representatividad territorial de las recolecciones. Además, se localizaron larvas de la plaga Spanolepis selloanae Gagné (Diptera: Cecidomyiidae) en inflorescencias de pliegos de Asturias y el norte de Portugal recogidos en 2018 y fechas posteriores, lo que confirma que la introducción de S. selloanaeen la península ibérica se produjo de forma independiente de la de C. selloana.
[Abstract] Herbaria are a useful source of information for the study of the geographic distribution and expansion dynamics of plants. Ininvasive alien species, variations in their geographic range and niche may occur in short periods of time, which can be observed in herbarium materials. Cortaderia selloana(Schult. & Schult.f.) Asch. & Graebn (Poaceae) is an invasive grass introduced as a garden plant, today widely naturalized along the north, west and east coast of the Iberian Peninsula. In this study, a complete review of the herbarium sheets of the species available in the Iberian public herbaria was carried out, in order to understand the history of its introduction and expansion in the Iberian Peninsula. A total of 155 sheets from 21 herbaria were received and reviewed, dating from the beginning of the 20th century to present day. The information collected in the sheets does not allow to describe the complete process of introduction and expansion in the studied territory, but it provides data on the distribution of specimens according to their invasiveness and sex over the decades, and the territorial representativeness of the sheets. In addition, larvae of the midge Spanolepis selloanaeGagné (Diptera, Cecidomyiidae) were found in inflorescences from Asturias and northern Portugal collected in 2018 and later dates, confirming that the introduction of S. selloanaeinto the Iberian Peninsula occurred later and independently from that of C. selloana.
