| Pollinators are able to discriminate among different floral phenotypes. Thus, flowers more attractive to pollinators usually receive more visits to their reproductive structures. However, this effect of attraction does not necessarily occur in a binary way, all-or-nothing. Loasa tricolor KerGawl. is an annual herb covered with stinging hairs. Flowers present a corolla with five yellow petals and red nectarine scales. In this study, we assess whether the variation in the floral phenotype of L. tricolor affects discrimination by pollinators, following a dose-dependent type of response. This study was carried out in a protected area of Chile where L. tricolor shows high levels of florivory, probably affecting its attraction to pollinators. We experimentally... |

| The indirect impact of flower herbivory on plant reproduction depends on the pollination environment, particularly on the presence or absence of pollinator species with the ability to discriminate damaged from undamaged flowers. The change in pollinator assemblages, due to habitat modification, may modify the impact of flower herbivory on plant reproductive success. In this work, we evaluate the effect of flower herbivory on the seed production of Viola portalesia (Gay) in two contrasting environments, a native and low-disturbed habitat and an extensively transformed habitat characterized by Pinus radiata plantations. Even though the two habitats differed substantially in the composition of pollinator assemblages and visitation rate, the flower damage... |
