Dr. Pere Casals Tortras.

Certification of scientific productivity and science and transfer activity for the program I3 (Agencia Nacional de Evaluación)

Specialist in plant and soil relationships in agrosilvopastoral systems. With a background in plant and soil sciences, I have a PhD in the University of Barcelona addressing plant and soil N dynamics after prescribed fires. Broad experience in studying soil nutrient cycling and organic matter changes as affected by fire and afforestation. Skills using 13C, 14C and 15N as a soil and plant tracers and soil C fractionation. Involved in research projects assessing the effects forest management, land-use and climate changes on plant and soil relationships.

In order to contribute to a sustainable management of agrosilvopastoral systems, my research interest focuses on the effects of management derived perturbations (i.e. prescribed fires, grazing) or land use and climate stresses (i.e. land abandonment, drought, temperature increase) on plant dynamics, nutrient cycling and organic C stocks and fluxes. At the present I am full-time researcher at the Forest Sciences Centre of Catalonia, working to contribute to the comprehensive understanding of burning-driven mechanisms that determine functional shrub composition and structure and key components of soil.
