Title: Plant-pollinator mutualisms as model system for biodiversity assessments and valuations                                                        

AbstractPollination has a major to play in the reproduction of angiosperms in natural and human managed ecosystems. Plant-pollinator mutualisms are also excellent systems to assess biodiversity and valuate ecosystem services. The contributions of plant-pollinator mutualisms in biodiversity research are:  1. Valuation of pollination services by wild and managed pollinators to commercially important crops, 2. Measuring risk of spread of transgenes spread to wild relatives of crop plants, and 3. Assessing plant-pollinator networks in ecosystem function. Case studies will be presented to illustrate these different aspects.
