Breeding system and pollination of woody species in a subtropical forest invaded by alien plants.
: Breeding system and pollination of woody species in a subtropical forest invaded by alien plants. In the riparian forest of Punta Lara (Buenos Aires province, Argentina) seven woody bird-dispersed species coexist, five of which are native (Ocotea acutifolia, Allophylus edulis, Myrsine laetevirens,...

Plantas invasoras selva ribereña biología reproductiva éxito de la polinización cargas de polen estigmáticas Argentina : Breeding system and pollination of woody species in a subtropical forest invaded by alien plants. In the riparian forest of Punta Lara (Buenos Aires province, Argentina) seven woody bird-dispersed species coexist, five of which are native (Ocotea acutifolia, Allophylus edulis, Myrsine laetevirens, Blepharocalyx salicifolius and Citharexylum montevidense), and two are invasive aliens (Rubus ulmifolius and Ligustrum lucidum). While seed dispersal of these species has been studied, other aspects of their reproduction are unknown. In this paper we studied the breeding systems, the quality of the pollination service they receive and their floral visitors. All species are xenogamous. One species (M. laetevirens) is anemophilous and the others are visited mostly by Diptera, Hymenoptera and Lepidoptera. For most of the native species the pollination service seems insufficient. In A. edulis and B. salicifolius natural fruit set was lower than that of hand cross-pollinated flowers, only O. acutifolia and the two exotic showed stigmatic pollen loads sufficient to achieve maximum seed production. A possible explanation for the patterns found lies in the reduction of populations of native species due to the expansion of the aliens, particularly L. lucidum. En la selva ribereña de Punta Lara (provincia de Buenos Aires, Argentina) conviven siete especies leñosas dispersadas por aves, de las cuales cinco son nativas (Ocotea acutifolia, Allophylus edulis, Myrsine laetevirens, Blepharocalyx salicifolius y Citharexylum montevidense) y dos son exóticas invasoras (Rubus ulmifolius y Ligustrum lucidum). Si bien allí se ha estudiado la dispersión de semillas de estas especies, otros aspectos de su reproducción son desconocidos. En este trabajo estudiamos su sistema reproductivo, la calidad del servicio de polinización que reciben y los visitantes florales. Todas las especies son xenógamas. Una especie (M. laetevirens) es anemófila y las demás son visitadas principalmente de Dípteros, Himenópteros y Lepidópteros. El servicio de polinización parece insuficiente en la mayoría de las especies nativas. A. edulis y B. salicifolius produjeron menos frutos en condiciones naturales que cuando se polinizó las flores con polen de otro individuo y sólo O. acutifolia y las dos especies exóticas mostraron cargas polínicas estigmáticas suficientes para alcanzar el máximo de producción de semillas. Una posible explicación de los patrones encontrados podría ser la reducción de las poblaciones de las especies nativas producida por la expansión de las exóticas, en particular de L. lucidum.
