Vegetation in water-limited ecosystems relies strongly on access to deep water reserves to withstand dry periods. Most of these ecosystems have shallow soils over deep groundwater reserves. Understanding the functioning and functional plasticity of species-specific root systems and the patterns of or differences in the use of water sources under more frequent or intense droughts is therefore necessary to properly predict the responses of seasonally dry ecosystems to future climate.

Después de la aplicación de los tratamientos de temperatura (control, 75°C 1 hora y 120°C 5 minutos), la germinación en el laboratorio de las semillas de las especies estudiadas ha sido diferente en cada una de ellas. [...]
Germination after the application of heat treatments (control, 75°C 1 hour, 120°C 5 minutes) has been different in each studied species. The germination of the seeds was increased by temperature treatments only in Phyllirea latifolia, a sprouter large shrub, and Cistus salviifolius, a seeder, rarely resprouter, small shrub. [...]
