Resumen
Species of the pantropical genus Erythrina (Fabaceae) are visited by perching and/or hovering birds in the mainland. At the oceanic island of Fernando de Noronha, north-eastern Brazil, we found that Erythrina velutina Willd. blooms during the dry season and the flowers are visited by a small vertebrate assemblage. Flowers last 2 days and their stigmas remain receptive, although only first-day flowers produce nectar. Nectar is dilute and produced copiously. All terrestrial native vertebrates (three of them endemics), the dove Zenaida auriculata noronha, the perching birds Vireo gracilirostris and Elaenia ridleyana, and the lizard Euprepis atlanticus are regular visitors and pollinators. The features of E. velutina conform to those of passerine-pollinated species within the genus. Its nectar is a resource sought by the vertebrates, which visit the inflorescences from dawn to sunset. Since none of the visitors depends on nectar as a major food source, the flowers are likely to serve a dual purpose, i.e. water balance and energy intake, similarly to the findings for some Erythrina species in Neotropic and Palaeotropic mainlands. However, E. velutina is the only species within the genus that is visited and pollinated by doves and lizards. © CSIRO 2009. 57 1 26 30 Baker, H.G., Baker, I., Floral nectar sugar constituents in relation to pollinator type (1983) Handbook of experimental pollination biology, pp. 117-141. , Eds CE Jones, RJ Little pp, Van Nostrand Reinhold Company: New York Bruneau, A., Evolution and homology of bird pollination syndromes in Erythrina (Leguminosae) (1997) American Journal of Botany, 84, pp. 54-71. , doi: 10.2307/2445883 Buzato, S., Sazima, M., Sazima, I., Hummingbird pollinated floras at three Atlantic Forest sites (2000) Biotropica, 32, pp. 824-841 Carleton, M.D., Olson, S.L., Amerigo Vespucci and the rat of Fernando de Noronha: A new genus and species of Rodentia (Muridae: Sigmodontinae) from a volcanic island off Brazil's continental shelf (1999) American Museum Novitates, 3256, pp. 1-59 Eifler, D.A., Patterns of plant visitation by nectar-feeding lizards (1995) Oecologia, 101, pp. 228-233. , doi: 10.1007/BF00317288 Etcheverry, A.V., Alemán, C.E.T., Reproductive biology of Erythrina falcata (Fabaceae: Papilionoideae) (2005) Biotropica, 37, pp. 54-63 Faegri, K., van der Pijl, L., (1980) The principles of pollination ecology, , Pergamon Press: Oxford, UK Galetto, L., Bernardello, G., Rewards in flowers.
