Spatial and temporal synchronicity in the phenological events of Prosopis flexuosa in the Central Monte Desert

Some desert plant species are capable of using underground water and are therefore independent of rainfall events. Species of the genus Prosopis are thought to be facultative phreatophytes, since they have deep and shallow roots that allow them explore water from underground layers and from sub-surf...
