Nectar is the main floral reward produced by angiosperms to pollinators, and can be consumed by both vertebrates and invertebrates. The temporal variation in nectar availability can affect the population dynamics and phenology of pollinators, which in turn are able to respond even to small variations in nectar production. Species with generalist pollination systems, nectar is the main resource responsible for attracting a wide variety of floral visitors. Species of the genus Inga (Fabaceae) produce flowers with brush-like morphology that secrete copious amounts of nectar, and are visited by many animal groups, including vertebrates and invertebrates of both diurnal and nocturnal. Inga vera is a mass flowering species widely used in restoration programs in Brazil. Since habitat restoration in biodiversity hotspots should also include the restoration of pollination services, it is important to understand the role of a keystone species on the dynamics of the local fauna pollinators as well as its indirect effects on the pollination of sympatric species. In this sense the aim of this study is to test whether the flowering and nectar production of a population of Inga vera affect the richness and abundance of bees, hummingbirds and hawkmoths in a restoration area of Cerrado, also, to test whether the flowering of I. vera produces indirect effects on sympatric hummingbird-pollinated species. To accomplish this, we will analyze the relationship between nectar production and the richness and abundance of floral visitors, and conduct an experiment with feeders to test the occurrence of indirect effects of I. vera on the visitation frequency of sympatric species.
