Global change and the genetic structure of grassland species (2001-2004)
Global change is expected to affect micro-evolutionary processes. Here, we took advantage of a long-term CO2 enrichment experiment in the field. Using molecular markers and quantitative genetics we analysed the population genetic consequences of enhanced atmospheric CO2 in several grassland species with different life cycles after six years of CO2 enrichment. Using RAPD-PCR and quantitative genetics we explored population differentiation in Scabiosa columbaria, a species probably suffering from isolation of its populations in remnants of calcareous grasslands.
