{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Reduction 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

Bredahl, Linda; Ro-Poulsen, Helge; Mikkelsen, Teis N.

Arctic, Antarctic, and Alpine Research — 2004, Volume 36, Issue 3, pp. 364-369

This study investigates effects of reducing the ambient UV radiation on gas exchange and chlorophyll fluorescence of two shrub species, Salix arctica and Vaccinium uliginosum, in a high arctic heath in Northeast Greenland in July and August. On two sites films, Mylar and Lexan, were used to reduce UV-B radiation and UV-B + A radiation, respectively. A UV transparent film, Teflon, and no film were used as controls. Field measurements showed that the plants under Teflon, Mylar, and Lexan received approximately 91, 39, and 17% of the ambient UV-B irradiance, respectively. Reduced UV radiation ...
