  • Forests play a major role in global carbon (C) cycle, and the carbon density (CD) could reflect its ecological function of C sequestration. Study on the CD of different forest types on a community scale is crucial to characterize in depth the capacity of forest C sequestration.

  • Plant species that invade an alien area and outgrow the native vegetation, establishing and increasing their own territory, often lead to negative economic, environmental, and social impacts. Even native species can behave like invasive species by their exponential spread. Similarly, not all non-native species are invasive. Many alien invasive species, however, do threaten the health and integrity of our terrestrial and aquatic ecosystems.

  • I had wanted to write something like this book for many years, but would probably never have dared to attempt it unless I had been asked to by Clive Horwood at Praxis Publishing. As it is, this has been a rewarding experience for me personally, something which has forced me to read literature that I would not otherwise have read, and to clarify things in my head that would have remained muddled.

  • Wildland fires are natural calamities that bring enormous environmental and economic damage worldwide and some of them cause human death. Achieving effective fire fighting is associated with the possibilities of predicting the characteristics of fire behaviour. Special attention needs to be drawn to meteorological conditions and their effect on fire spread in a bed of vegetation. On the other hand, studying the effect of forest fires on the environment is of equal significance for building the strategy and specific actions to be undertaken in the fire fighting process.

  • The sensory networks that transduce information starting with the capture of a photon into a suite of downstream responses are well known. Historically these pigments were postulated to control various aspects of plant growth and development, particularly germination, phototropic movements and the transition between vegetative and reproductive growth. Long before the genes and proteins were identified and characterized, a tremendous body of work produced evidence of their activities and effects on physiology. Light quality effects on germination were examined by Lewis H.

  • Forest ecosystems cover large parts of the terrestrial land surface and are major components of the terrestrial carbon (C) cycle. Most important, forest ecosystems accumulate organic compounds with long C residence times in vegetation, detritus and, in particular, the soil by the process of C sequestration. Trees, the major components of forests, absorb large amounts of atmospheric carbon dioxide (CO2) by photosynthesis, and forests return an almost equal amount to the atmosphere by auto- and heterotrophic respiration.

  • The issues related to non-market forest goods and services involve social and economic dimensions. Unlike market forest goods and services, non-market ones are not traditionally traded and their value is not defined by the market price. At the same time the access to non-market forest goods and services is largely unlimited and free in most of the EU Member States. These characteristics of non- market goods and services, combined with their growing importance and social demands, can lead to an un-sustainable management of these goods and services. ...

  • Today, the budget structures of the two countries show many formal similarities, but the de facto operations of central and sub-national bureaucracies diverge. Most Western discussions of fiscal efficiency start from the assumption that there is a separate, tax-based fiscal system in place. However, neither Russia nor China has succeeded fully in establishing an effective, tax-based system for provision of local infrastructure, pensions, and a social safety net. The reform of the governmental fiscal system in each country is incomplete.
