Abstract:Artemisia monosperma\% is a dominant desert small shrub occurring in active sand dunes and stabilized sand fields. A cyanobacterial crust develops on stabilized sand and, as a result, runoff water may occur after rains. The mucilaginous seeds may float on the runoff water and disperse into depressions or cracks. In these experiments, almost half of the seeds remained afloat on distilled water for 3 days and on different concentrations of salt solutions, more seeds remained afloat for longer. Lower concentra...
