In evolutionary time scales natural disturbances have affected the
vegetation on Earth. During the Quaternary the forest biomes of the
tropics were subjected to manifold disturbances. Climate changes
and climate oscillations were associated with changing
precipitation and drought regimes, flooding, siltation, landslides,
etc. The prehistorical forest was also influenced by the effects of
large wildlife populations. Large-scale catastrophies in the forest
biomes were mainly caused by abiotic environmental alterations, the
small-scale disturbances were and still are related to both biotic
and abiotic processes. Both the large-and the small-scale
disturbances have played a significant role in shaping
distribution, dynamics, structure and composition of the
paleoforest. After the expansion of hominids and early humans, and
later, by modern humans, the anthropogenic influences on the
tropical forest began to overlap natural disturbances. Today's
anthropogenic impacts on the tropical forests differ qualitatively
and quanitatively from the natural disturbances. The speed of
tropical deforestation and savannization is dramatically
increasing. The physical and chemical impacts of forest conversion
and biomass burning add to other anthropogenic influences on the
atmosphere and climate. The expected anthropogenic climate change
will also have considerable impacts on the tropical flora and
fauna. The book on "Tropical Forests in Transition" synthesizes
information on changing environmental conditions and human impacts
on the tropical forest by looking back to the paleoecology,
analyzing the impact of modern human populations and modeling the
future of the tropical forest in a changing environment. The aim of
the book is to strengthen multidisciplinary thinking in disturbance
ecology.
