The Effect of Dew and Fog on Lithic Lichens Along an Altitudinal Gradient in the Negev Desert

The effect of dew upon lichen communities was studied in three sites along an altitudinal gradient in the Negev Desert. The sites [Nizzana, NIZ (250m a.s.l), Sede Boqer, SB (530m a.s.l.) and Har Harif, HH (990m a.s.l.)] have similar rain precipitation (∼100 mm) but different dew precipitation of 0.1...

Description
Summary:The effect of dew upon lichen communities was studied in three sites along an altitudinal gradient in the Negev Desert. The sites [Nizzana, NIZ (250m a.s.l), Sede Boqer, SB (530m a.s.l.) and Har Harif, HH (990m a.s.l.)] have similar rain precipitation (∼100 mm) but different dew precipitation of 0.11, 0.21 and 0.32 mm, respectively. A clear gradient was found for the chlorophyll content with NIZ (38.6 mg m −2 )
