Chapter 5 Monitoring Changes in Genetic Diversity Michael W. Bruford, Neil Davies, Mohammad Ehsan Dulloo, Daniel P. Faith and Michele Walters Abstract DNA is the most elemental level of biodiversity, drives the process of speciation, and underpins other levels of biodiversity, including functional traits, species and ecosystems. Until recently biodiversity indicators have largely over- looked data from the molecular tools that are available for measuring variation at the DNA level. More direct analysis of trends in genetic diversity are now feasible and are ready to be incorporated into biodiversity monitoring. This chapter explores the current state-of-the-art in genetic monitoring, with an emphasis on new molecular tools and the richness of data they provide to supplement existing approaches. We also briefly consider proxy approaches that may be useful for many-species, global scale monitoring cases. Keywords Biodiversity Á Molecular tools Á Genetic diversity Á Variation Á Monitoring M.W.
