Education

  • B.S. (Biology) – University of Salamanca.
  • Ph.D. (Biology) – University of Salamanca.

Research Interests

  • Growth dynamics of the leaf biomass in woody species.
  • Photosynthesis and nutrient use efficiency in tree species differing in leaf longevity.
  • Relationships among leaf life span, leaf traits (anatomy, morphology, nutrient contents and fiber concentrations) and productivity.
  • Nutrient resorption during leaf senescence.
  • Leaf strategies and gas-exchange patterns in different growth stages in Mediterranean tree species.
  • Morphological and physiological responses to drought and temperature stress in Mediterranean tree species differing in leaf life span.
