Effect of global climate change on plant ecological processes

Despite the effort of the international climate change negotiations the carbon-dioxide concentration of the Earth is expected to double by 2100 compared to its recent concentration (382 ppm). The increasing emission of carbon-dioxide (CO2) to the atmosphere changes the bio-geochemical cycles of the Earth. However, not only through changing the climate but also trough affecting the plant metabolism and global carbon capture of the ecosystems. Therefore, it is important to understand the behaviour of natural and managed ecosystems in elevated CO2 concentrations.

The aim of the research is to investigate the effect of elevated CO2 concentartion and increasing air temperature on long term plant ecological processes. The subject of the study are grasslands and croplands of the Carpathian Basin and and croplands

During the research we observe the effect of simulated and observed climate change on plant and vegetation structural and functional aspects (biomass production, soil/plant respiration, ecophysiological processes). To simulate climate change i.e. elevated CO2 concentartions we are using open top chambers (OTC) in the Botanical Garden of the University.
