Última Pollination and breeding system in Adesmia bijuga Phil. (Fabaceae), a critically endangered species in Central Chile Gayana Botánica GÓMEZ P,PERSY; LILLO,DIANA; GONZÁLEZ,ALEJANDRA V. Adesmia bijuga Phil. is an endemic shrub in central Chile, classified as a critically endangered species of plant. After more than 100 years since its original description by R. A. Philippi (1884), the species was rediscovered exclusively in two locations of the Maule Region. One of them, Fundo San Pedro-Las Cañas, is close to extinction with a low number of shrubs, occurring in a disturbed habitat due to plantations of Pinus radiata. This study examined the pollination biology and breeding system of A. bijuga in order to explain their small number of shrubs. We estimated composition of pollinator species attracted to flowers and visitation rates. In order to describe its breeding system in A. bijuga we used manipulated treatments to estimate autonomous...

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...
