Resumen:
The expansion of the Prosopis genus from the sub-humid Chaco towards
colder and drier zones such as Monte, Prepuna and Patagonia .biogeographical
regions would have implied the acquisition and/or adjustment of morphological
and physiological adaptations to stressful environments. In this chapter, we discuss
the phenological, morphological and physiological features of seven Prosopis

the phenological, morphological and physiological features of seven ProsopisProsopis
species native to Argentinean arid regions that allow them to avoid or tolerate
water stress, salinity, and other environmental stress factors in arid lands. Some of
these adaptations appear to be spread over the genus and should confer the
capability to deal with the most common stressful factor of arid lands (i.e. water
availability); however, other morphological or physiological adaptations appear to
be specific to each species, and should be the cause of niche differentiation among
species and the occupation of particular environments within arid lands (e.g. sand
dunes, salive environments). Finally, we díscuss some consequences of these
adaptations for the management of Prosopis species. The inter- and intra-specific
variability observed in their adaptation to stressful factors suggest that some
