I work in the dynamics and conservation of mountain plant diversity: population dynamics, plant-animal interactions, and life history evolution.


At the species and population level, I often use an integrative approach (the whole life cycle and population structured models) at large spatial and temporal scales. I focus on plant adaptations, explore plant performance under present conditions, and project viability in future scenarios. Different fitness components (germination, growth, survival, fecundity…) are combined to show their weighted importance and to get standardized comparative parameters.


I am also interested in testing to what the extent species at the limit of distribution show distinctive ecological or demographic traits compared to central populations, and small populations compared to large ones, particularly for the Pyrenean flora. In the latter case, we are also exploring differences in the network of plant-animal interactions, and the important role of threatened plants to sustain local biodiversity.


My highest effort at present is invested in the coordination of a monitoring network for plant population trends and habitat changes in the Aragon region. The network involves more than two hundred volunteers and rangers. An important part of such network is developed under a LIFE+ European project (www.liferesecom.com). Annual population censuses, abundances, or individual monitoring are being carrying out for more 250 populations across NE Spain. Among the 180 plant species surveyed, there are 60 threatened, 65 alpine, and 70 indicators of climatic change.
