Measuring the influence of phylogenetic relationships on floral visitation

Abstract

Pollinators are attracted to flowers based on the sensory information they gather concerning the flower they pollinate, and decide to visit the flower, or not. Closely related plants have similar traits because of their similar genetics, and consequently will attract similar pollinators. The abundance of floral visitors a plant gets is dependent on its ability to attract pollinators and the frequency of floral visitation can be able to be predicted based on the phylogenetic isolation of a focal species. Phylogenetic isolation may be a logistically easier way to predict floral visitation than measuring morphological similarities. There exists a positive relationship between the number of visitors a species gets and the phylogenetic distance (in millions of years) to its nearest neighbor. There also exists a marginal negative relationship between the rate of floral visitation and the mean phylogenetic distance of a focal species in the community.
