Aquatic foodweb modelling of Lake Vättern, Sweden

• The potential of ancient DNA research is far reaching in evolutionary studies and offers many opportunities, several of which have been little explored in plant palaeoecology. Recent genetic studies of fossil pollen of Scots pine retrieved from postglacial lake sediments in Sweden showed that chloroplast DNA can be recovered and used from remains as old as 10 ka. By sequencing and comparing short, yet very informative, chloroplast DNA regions from fossil and modern specimens we can now read the evolutionary message inscribed in this genome and learn how specific regions have evolved after the last glaciation. Can this approach be used also to study the evolutionary changes occurred both in time and space in plant populations during the last glaciation?
