Abstract

Floral and pollinator traits have an important role structuring plant-pollinator interactions at the community level, via 1) phenotypic complementarity or when legitimate interactions are restricted through 2) exploitation barriers. However, the relative importance of this dual role has been overlooked. Since pollination may be crucial for plant populations, the floral traits can influence the community organization. Moreover, if this traits determine relative fitness differences between the species, this traits can lead to coexistence mechanisms. This project aims to investigate how species tratis structure the interactions, the plant community and the distribution of the fitness in a highland grassland vegetation in the southeastern Brazil. The temporal and spatial distribution of the floral traits will be evaluated monthly in the field. The plant-pollinator interactions will be recorded in the field and we will quantify the female and male components of the plant reproductive success. We will analyze floral morphology, color and reward and the mouthparts and spectral sensitivities of the pollinators. We will analyze the role of the traits (phenotypic complementarity - PC or exploitation barriers - EB) using theoretical models and its influence in (1) properties of the plant-pollinator network (2) plant community assembly and (3) distribution of the fitness between the speces. We expect that (1) the interactions exhibit a better fit to the model with both roles of the floral traits. Furthermore, (2) this tratis structure the plant community, reflecting the interaction modules and (3) plants flowering in periods of high functional diversity (higher modularity) will have higher fitness, since it would reduce plant-plant competition for pollinators.
