- Abstract
- Rhinanthus minor L. and R. angustifolius Gmelin are annual hemi-parasitic Orobrancaceae growing in very similar ecological niches and both bumblebee- pollinated. The flowering periods and geographical ranges of these species largely overlap in Europe, and in certain localities hybridation and introgression occur. In our lab and in the field we try to understand how this natural hybridation works by exploring the ecological, ethological and physiological borders between these two closely related species. We have measured pollen tube growth rates in con-specific and hetero-specific styles and performed observations in the field on bumblebee species richness, visitation rates, and behaviour. The data are still being analysed and only some preliminary results will be presented. Other experiments such as pollen competitive ability in mixed pollinations (hybrid detection via molecular tools), and quantifying bumblebee pollen uptake and deposition according to transition behaviour are also envisaged in the project.
