The project aims to relate functional attributes involved in the uptake and use of resources (mainly water and nutrients) with different post-disturbance (fire) response syndromes of Mediterranean plant species. The final goal is to evaluate the consequences of fire regime on the functioning of Mediterranean ecosystems. We assume that different fire regimes may lead to changes in the post-disturbance response of the community, which is correlated to functional properties. The project includes several studies following complementary approaches: 1.Effect of fire regime on the success of the different regenerative responses. We will conduct extensive surveys of the success of the different regenerative responses in areas submitted to different fire regimes. We will also study the dynamics of the species belonging to the different regenerative strategies by a simulation model based on life-history attributes, which includes the spatial distribution of organisms. 2.Characterization of the function attributes involved on the uptake and use of resources of the different regenerative syndromes. We will take field measures of leaf and architectural attributes, together to isotopic discriminations (which are integrative estimations of the use efficiency of resources such as water) of species belonging to the different regenerative groups. These field campaigns will be performed across a biogeographical gradient of water availability. We will also evaluate the correlation between regenerative and functional traits of the Mediterranean shrub flora of the Iberian peninsula by multivariate analysis of data obtained from literature and direct observations. 3.Effect of fire regime on the ecosystem functioning. We will conduct extensive surveys in areas submitted to different fire regimes where parameters related to the cycles of energy and nutrients will be estimated. Finally, we will develop a model of growth (and related functional parameters of the ecosystem) (...)
