MARC recordReduction of the ambient UV-B radiation in the High Arctic increases Fv/Fm in Salix arctica and Vaccinium uliginosum and reduces stomatal conductance and internal CO₂ concentration in Salix arctica / Linda Bredahl, Helge Ro-Poulsen, Teis N. Mikkelsen.

| Abstract: | Investigates effects of reducing ambient UV radiation on gas exchange and chlorophyll fluorescence of two shrub species, Salix arctica and Vaccinium uliginosum in heath in north-east Greenland. Results indicate that net depletion of stratospheric ozone layer has increased UV-B radiation in High Arctic to extent that reduction of UV-B irradiance on S. arctica and V. uliginosum result in frequent increases in Fv\Fm and reductions in gs and Ci without affecting Pₙ. Notes possibility that observed short-term effects could result in long-term negative effects on growth and survival for investigated species. |
