The understanding of the impact of extreme climatic events under a global climate change scenario is crucial for the accurate forecast of future plant community dynamics. We have experimentally assessed the effect of drier and wetter summer conditions on the recruitment probabilities and the growth of seedlings from eight woody species representative of the most important functional groups in the community, pioneer shrubs, mid-successional shrubs and trees, across the main habitats in the study… 
Differential impact of hotter drought on seedling performance of five ecologically distinct pine species
Assessing the effect of future climatic conditions on the performance of five ecologically distinct pine species common in Europe hypothesised that Mediterranean species inhabiting dry, low-elevation sites will be less affected by the expected warming and drought increase thanspecies inhabiting cold-wet sites.
Effects of Quercus suber Decline on Woody Plant Regeneration: Potential Implications for Successional Dynamics in Mediterranean Forests
In the last two decades, widespread tree decline and mortality have been documented in forests worldwide. These mortality events usually show certain level of host-specificity, translating into rapid
Effects of Climate Change on Forest Regeneration in Central Spain
The Mediterranean climate has dry and hot summers, which is harsh for plants, especially seedlings. During the 1950s and 1960s, most reforestations carried out in Central Spain, a Mediterranean
Oak regeneration at the arid boundary of the temperate deciduous forest biome: insights from a seeding and watering experiment
Oaks regeneration and thus forest dynamics may be limited by different factors at a biome boundary compared to its core areas, and this very simple mechanism (inability of oak regeneration in grassland habitats) may contribute to the opening up of the closed forest biome, and the emergence of a biome transition zone.
Growth and stable isotope signals associated with drought-related mortality in saplings of two coexisting pine species
Drought-induced events of massive tree mortality appear to be increasing worldwide. Species-specific vulnerability to drought mortality may alter patterns of species diversity and affect future


Alleviation of Summer Drought Boosts Establishment Success of Pinus sylvestris in a Mediterranean Mountain: An Experimental Approach
Summer drought limits Pinus sylvestris establishment in these southernmost forests by reducing both recruitment and growth, which might lead to the development of a remnant dynamic in these relict populations under the current regional increase in dryness and rainfall variability associated with global warming.
Experimental evidence of reduced diversity of seedlings due to climate modification in a Mediterranean‐type community
The results show that demographic processes are sensitive to minor climate changes, with probable consequences on the diversity and structure of the future plant communities.
Soil water content and emergence time control seedling establishment in three co-occurring Mediterranean oak species
It is suggested that temporal and spatial variability of soil water content, mediated by emergence time and seed size, play a crucial role in the regeneration dynamics of Mediter- ranean oak forests.
Herbivory and plant growth rate determine the success of El Niño Southern Oscillation‐driven tree establishment in semiarid South America
While climatic extremes are predicted to increase with global warming, we know little about the effect of climatic variability on biome distribution. Here, we show that rainy El Niño Southern
Performance of seedlings of Mediterranean woody species under experimental gradients of irradiance and water availability: trade-offs and evidence for niche differentiation.
Evidence is found of some of the trade-offs previously reported for non-Mediterranean plant communities, such as between survival in the shade and relative growth rate (RGR) at high light, but no evidence for others.
Soil‐nutrient availability under a global‐change scenario in a Mediterranean mountain ecosystem
Changes in rainfall availability will alter soil‐nutrient availability under a climate‐change scenario. However, studies have usually analyzed the effect of either drier or wetter soil conditions,
The results show that pioneer shrubs facilitate the establishment of woody, late-successional Mediterranean spe- cies and thus can positively affect reforestation success in many different ecological settings.
Drought-induced shift of a forest-woodland ecotone: rapid landscape response to climate variation.

The most rapid landscape-scale shift of a woody ecotones ever documented is reported: in northern New Mexico in the 1950s, the ecotone between semiarid ponderosa pine forest and pinon-juniper woodland shifted extensively and rapidly and persisted for 40 years.
