Abstract

Flower color is a major trait for communication between plants and their pollinators. The diversity of flower color may be the result of the selective pressure exerted by pollinators, which feature a wide range of visual systems, differing in the way they perceive and select colors. However, color diversity varies in space and time, affecting resource distribution to floral visitors and influencing visual communication between plants and pollinators. This variation is directly related to species composition and vegetation structure, being a determinant factor in naturally heterogeneous environments, as the rocky grasslands. This vegetation is composed by a mosaic of vegetation characteristic of mountain regions, with high species diversity and endemism, providing a natural environment unique to investigate flower color diversity and its importance to the species spatio-temporal connection in the landscape. In this project, we intend to evaluate flower color of species present in the vegetation mosaic of the "Cadeia do Espinhaço" rocky grasslands (Serra do Cipó, Minas Gerais, Brazil), according to pollinators' visual systems, aiming to answer: (i) which is the color pattern of those vegetation types and whether there are spatio-temporal differences in color diversity according to the type of vegetation and the altitudinal gradient; (ii) whether the combination of visual (related to colors) and non-visual traits for attraction are related to the pollination vectors and whether those traits are phylogenetically related; and (iii) which are the possible environmental filters of those floral traits in a spatial and temporal and phylogenetic context. We expect to find influence of plant species diversity and composition, environment and pollinators systems in the spatio-temporal pattern of flower color diversity across vegetation types and the altitudinal gradient of the studied rocky grasslands
