Resumen. Las proyecciones del cambio climático indican que en el área mediterránea se producirá un aumento en la frecuencia de sequías extremas, lo que causará impactos en sus masas forestales y en los servicios ecosistémicos que estas prestan. En los últimos años se han registrado eventos de decaimiento y mortalidad asociados a fuertes sequías, lo...
What are the changes at individual and community level derived from altered climatic regime in a typical secondary Mediterranean shrubland?
Land surface phenology (LSP) is described as the seasonal pattern of variation in vegetated land surfaces observed from remote sensing. Vegetation phenology derived from remotely sensed multi-temporal satellite imagery can be used as a bio-indicator for climate change thanks to the strong relationship between phenology and Climate. In previous work...
The frequency and magnitude of climate extremes are expected to increase in the future according to climate change forecasts.Forest mortality is, among others, a consequence of extreme drought events caused by of the increase of temperature and the decrease of precipitation. In the last years, forest mortality induced by events of extreme drought w...
The main goal of the Project is to evaluate the effect of Global Change (intense droughts and recurrent fires) on the functionality of plant communities and its consequences on water balance and aquifer recharge.
Water is a limited and scarce resource in the Mediterranean area. IPCC projections indicate a rise in temperature and a decrease of rainfall in the region. Drier and warmer conditions will increase water stress and will promote the incidence of forest fires, particularly the recurrence of large fires. Water status of plant communities and species composition is a key component that can modulate the incidence of fires and their resilience after disturbances. In the last 60 years, climatic conditions in the province of Alicante (SE of Spain) have changed significantly. Year 2014 marked a negative record in terms of rainfall and can be considered as an example of a future condition (Garcia de la Serrana et al., 2014). As a consequence of that drought, plant mortality and decay processes were largely observed and may produce changes in the species composition of communities and can lead to an increased risk of fires. Furthermore, changes in the fire regime, particularly in the recurrence, produce deep changes in the structure and composition of vegetation. The concatenated interaction of these factors (drought and fires) can dramatically change the structure and composition of vegetation in drylands. In this context, the main objective of SURVIVE-2 is to assess the impact of two major stress factors in the Mediterranean (drought and fire disturbance) and its synergy in the dynamics of species and communities in Mediterranean ecosystems. In this sense, we have planned observational and manipulative experiments about the effect of the 2014 drought in these communities and the introduction of fire and/or rainfall reduction. We will analyze the impact of these stresses on plant communities and some species to understand what factors are playing a key role in the decay and mortality processes. We will also analyze how these factors impact on the overall ecohydrological dynamics of the community. In this new proposal, we incorporate experiments with recurrent fires that may contribute to understanding how changes in plant communities are modulated by fire and drought.
