Module aim (aims)
The lecture provides information about novel techniques investigating past global changes using biotic and abiotic indicators. Especially important in this context are high resolution (preferably annual) multi-proxy studies revealing in detail how environmental changes – including human impact – have disturbed various types of natural ecosystems. Terrestrial archives (e.g. soils, lakes and peatlands) give an opportunity to reconstruct precisely past climatic and human induced changes. From each of those archives several biotic or abiotic proxies (e.g. testate amoebae, plant remains pollen, plant macrofossils, chironomids) can be extracted. Those proxies are used to reconstruct past environmental variables such as temperature, precipitation or soil wetness. Furthermore, long-term ecology methods can also be used to reconstruct the land-use changes e.g. deforestation and soil erosion. The lecture presents theory, methods and several case studies of scientific research on the recent climatic changes and human impact. what is more, it also shows the importance of combination of neo-ecology and palaeoecology as the source of highly relevant information that improves palaeoenvironmental reconstructions.
