Post-Glacial Development of Climate and Forest Ecosystems,rical development and expansion of forest ecosystems. Apart from ongoing human impacts on the climate system (Chap. 4), there exist a number of external and internal factors that cause long- and short-term changes of the Earth’s climate. Among them are variations in the cosmic ray and material fluxe

Present State of Forest Ecosystems,se the most important territories for primary production on land. Today, forests and open woodlands still cover approximately one third of the total global land surface area of 149 million km2; however, the global forest area is reduced by approximately 0.37% annually (Richards 1990; Dixon et al. 19

Scenarios of Future Changes,to future climatic changes, paleoclimatic data from past eras were employed by Budyko and collaborators. Their method of paleoclimatic analogy is based on estimation of the temperature sensitivity of carbon dioxide (C02), the principal trace gas of climatic relevance. Changes in C02 that occurred du

Human Impacts on Central European Forests: Summary and Conclusions,ifferent phases of their life cycle, forest ecosystems can approach flux equilibrium and, thus, a steady State. The steady State reflects the adaptation of the system to the boundary conditions set by climate, soil conditions and human impacts; it is characterised by a specific composition of key sp
