Acclimation of tree function and structure to climate change and implications to forest carbon and nutrient balances

Abstract

Before large-scale anthropogenetic emissions the environmental factors have been rather stable for thousands of years, varying yearly, seasonally and daily in rather regular manners around some mean values. In this century the emissions of CO{sub 2}, sulphur and nitrogen from society to atmosphere are changing both atmospheric and soil environment at rates not experienced before. The fluxes to soil affect the contents of plant available nutrients and solubility of toxic compounds in the forest soil. Additionally, the chemical state of soil environment is coupled to tree growth, litter production and nutrient uptake as well as to the activity of biological organisms in soil, which decompose litter and release nutrients from it. Trees have developed effective regulation systems to cope with the environment during the evolution. The resulting acclimations improve the functioning of the trees if the environmental factors remain within their range of variation during the evolution. Outside the range the results of the regulation are unpredictable. The acclimative changes caused by the action of the regulation system may considerably change the response of trees to present environmental change. The analysis of the effects of present environmental change on forests requires simultaneous treatment of the atmosphere, forest soils and trees.  More>>

The analysis of the effects of present environmental change on forests requires simultaneous treatment of the atmosphere, forest soils and trees. Each of these components is dominated by its own features. The analyze of material and energy fluxes connect them to each other. The aim of this research is to analyse changes in the forest soils and reactions of trees to changes in the atmosphere and forest soils under a common theoretical framework, enabling combination of the obtained results into a holistic analysis of the response of forests to the present environmental change}
