With the aim of predicting the consequences of man-made climate change for Mediterranean ecosystems, geoscientists at Heidelberg University have studied natural climate and vegetation fluctuations over the past 500,000 years. The focus was on how these fluctuations have affected forests in the Mediterranean region. To this end, the researchers led by Dr. Andreas Koutsodendris analyzed fossil pollen preserved in a sediment core from Greece. ...
