DESCRIPTION:The Global Change Research Institute (CzechGlobe) forms a part 
 of the Czech Academy of Sciences. The activities of CzechGlobe focus on is
 sues of global climate change\, which by its nature and possible consequen
 ces extends beyond the basic thematic segments of atmosphere\, ecosystem\,
  and socio-economic system. The mission statement of the Division of Impac
 t Studies and Ecophysiological Analyses is to investigate molecular (key m
 etabolic pathways) and physiological mechanisms responsible for adaptation
 \, acclimation\, and resistance of plants to the effects environmental per
 turbances (in particular elevated CO2 concentration\, temperature extremes
 \, drought periods\, and changes in spectral composition of light and nutr
 ition supply etc.). Moreover\, the Division focus on the development and a
 pplication of new methodological approaches in environmental metabolomics\
 , phenotyping and early-stress detection in plants.\nA complex investigati
 on of plants responses\, in particular connected with processes of carbon 
 uptake\, to different sky conditions (radiation quality\, temperature\, va
 pour pressure deficit etc.) represents one of the major methodological app
 roaches. We have elucidated\, among other things\, increased light use eff
 iciency of ecosystem carbon uptake under cloudy sky conditions with prevai
 ling diffuse radiation and how forests maintain a positive C balance\, des
 pite having an apparently high self-shading degree. Penetration of diffuse
  radiation into lower canopy depths has direct effects on the productivity
  and structure of vegetation and is crucial for the modelling of global C 
 cycle. We have also shown that a stimulation of photosynthesis rate by an 
 elevated atmospheric CO2 concentration (EC)\, in contrary to clear sky\, i
 s negligible or even reduced under cloudy sky conditions. Such reduction i
 s associated mainly with EC-stimulated thermal dissipation of absorbed lig
 ht energy and insufficient openness of stomata. This result indicates that
  an expected increase in cloud cover associated with climate warming may r
 educe the stimulatory effect of EC on plants C uptake and growth.
