E. S. Mistakidis,G. E. Stavroulakistures of N, C and S compounds due to fractionation. Thus, tracing processes of isotopic fractionations in forest ecosystems can help identify transfer pathways and capacities. Atmospheric nitrogen pollution has been recognised as the cause for formerly N-limited forests to approach N saturation (.,

Many organism groups, bacteria, fungi and certain soil animals, possess this capability, and the product formed is generally ammonia/ammonium, depending on the soil pH. Ammonium (NH..) can

Tree Biomass, Growth and Nutrient Poolsview of global change and production of woody raw material. Furthermore, in forest ecosystems the bio-geochemical cycles of carbon and mineral nutrients, particularly nitrogen, are intimately related because foliage nutrient content strongly controls carbon assimilation by forests and, therefore, their primary productivity (.).

Soil Respiration in Beech and Spruce Forests in Europe: Trends, Controlling Factors, Annual Budgets om the atmosphere, while respiration releases CO. into the atmosphere. Ecosystem respiration includes autotrophic and heterotrophic processes: the first is caused by the growth and maintenance of plant tissues, while the second is mainly the result of the decomposition of litter and soil organic matter brought about by microbial biomass.
