Article
Full-text available
Key message Aleppo pine stands resilience can be increased by introducing local resprouting hardwood species. Pine density management impacts seedlings establishment by modifying resources availability and abiotic stress. Under Mediterranean conditions moderate pine density should be preferred to promote seedlings establishment. Abstract Context:...
Article
Full-text available
Resprouter species are important for Mediterranean ecosystem resilience, but they are scarce in landscapes dominated by pioneer pines. Sound knowledge of resprouter seedling functional responses and establishment success across different pine habitats would help guide forest restoration efforts. Four broadleaved resprouter species, that is two shru...
Article
Shrubs have been shown to facilitate tree seedling establishment in open Mediterranean ecosystem habitats, but their effects in forests have been much less explored. We investigated the role played by shrubs in seedling emergence, survival and growth for two co-occurring oak species – Quercusilex and Quercuspubescens – in the understory of clear Al...
Article
Increasing drought caused by the on‐going climate change, and forest management by thinning that aims at mitigating its impact, may modify the current relationships between forest functions and drought intensity and preclude our ability to forecast future ecosystem responses. We used 15 years of data from an experimental rainfall exclusion (‐27% of...
Article
In northern Mediterranean forests, increasing drought stress due to the on-going climate change is combined with stand ageing due to the lack of management. Management by thinning may alleviate drought stress by reducing competition, but its application is challenging in coppices of resprouting species where its long-term consequences for tree demo...
Article
Mediterranean forests face an intensification of droughts caused by ongoing climate change. To improve our understanding of tree and forest responses to increasing drought, we explored over nine years, the effects of a 30% rainfall exclusion experiment on the water potential, sap velocity and primary and secondary growth of two co-occurring species...
Article
Full-text available
Resprouter species are of great interest for Mediterranean forest resilience as they can survive fire or drought by activating dormant vegetative buds to produce regrowth. Understanding which factors control the early growth and survival of these species is needed to develop strategies to enhance stand resilience. In this study, three broadleaved r...
Article
Full-text available
(1) Climate change might impact tree fecundity by altering the relative influences of meteorological and physiological drivers, and by modifying resource investment in reproduction. (2) Using a 13-year monitoring of Quercus ilex reproduction in a rainfall exclusion experiment, we analysed the interactive effects of long-term increased aridity and o...
Article
Full-text available
How plant–plant interactions will interact with global change drivers such as increased drought during the regeneration phase is a key question to forecast future vegetation dynamics. Chemical interaction and especially allelopathy and drought have been suggested to affect plant performance synergistically, i.e., that plant under drought stress wou...
Article
Full-text available
Recent studies have identified strong relationships between delayed recovery of tree growth after drought and tree mortality caused by subsequent droughts. These observations raise concerns about forest ecosystem services and post-drought growth recovery given the projected increase in drought frequency and extremes. For quantifying the impact of e...
Article
Leaf litter, at the interface between the soil and the atmosphere, releases Biogenic Volatile Organic Compounds (BVOC) which play an important role both in global atmospheric chemistry and plant ecology. Litter is especially important in the Mediterranean region, where it is produced in high amounts and decomposes slowly. Only leaf litter emissions...
Article
Forest cover creates a specific microclimate by buffering most environmental variables. If the influence of the overstory on microclimatic variables has been well studied, the role of the understory has received less attention. In this study we investigated how the shrub layer modifies solar radiation, air temperature (T), relative air humidity (RH...
Article
Chemical interactions in forested ecosystems play a role in driving biodiversity and ecosystem dynamics. Plant phenolics released by leaching can influence surrounding plants and soil organisms such as bacteria, fungi or arthropods. However, our knowledge about such chemically-mediated biotic interactions in Mediterranean oak forests is still limit...
Article
Full-text available
Mediterranean holm oak coppices facing climate change : thinning can improve drought resistance Tree growth limitations under Mediterranean climate arise from both low winter temperature and drought stress during summer. Rising temperature and increasing drought induced by the on-going climate change are affecting holm oak forests productivity and...
Article
Full-text available
Background & AimsOak seedling establishment is difficult and may be partly explained by litter-mediated interactions with neighbors. Litter effects can be physical or chemical and result in positive or negative feedback effects for seedlings. Mediterranean species leaves contain high levels of secondary metabolites which suggest that negative litte...
Article
Full-text available
Plant–plant chemical interactions in forests can have a strong impact on the biodiversity and dynamics of these ecosystems, particularly in Mediterranean forests where plants exhibit a high secondary metabolite diversity. Allelopathic interactions in Mediterranean ecosystems have been mostly studied in the first stages of ecosystem dynamics, shrubl...
Article
Mixed plantations have been receiving increasing attention for their documented or supposed potential benefits over monospecific plantations. In particular, the use of neighbouring (or nurse) vegetation around target plants can enhance their performance through limitation of the competing herb layer, and can also improve their morphology.
Thesis
Full-text available
Installation d’espèces feuillues en forêt de pin d’Alep : interactions avec les strates arborées et arbustives. L’installation de plantules est une phase critique fortement influencée par les interactions avec la végétation établie - compétition ou facilitation. Dans cette thèse, nous montrons que l’effet du pin d’Alep ou d'arbustes sur l’installat...
Article
The role of biodiversity for soil processes remains poorly understood. Existing evidence suggests that functional diversity rather than species richness is relevant for soil functioning. However, the importance of functional diversity has rarely been assessed simultaneously at more than one trophic level, critically limiting the prediction of conse...
Article
Full-text available
Sowing acorns from Mediterranean oaks is an age-old practice around the Mediterranean Rim that has been largely replaced by planting seedlings. In this article, we assess the method overall and reconsider it in the light of recent experimentation carried out notably in South-East France and in the north of Spain. First we describe the advantages an...
Article
The regeneration phase is a critical step in plant population dynamics, but is still incompletely understood owing to the intricacy and complexity of the factors concerned. We investigated the role played by pine emergence, survival and growth in the recruitment process of a Mediterranean pine forest under disturbances of various intensities. Distu...
Conference Paper
Full-text available
http://medpine5.ctfc.es/ Session Stand dynamics and forest management, Thursday 25 th Sept 56 Developing silvicultural methods to adapt pine forests to climate change has become a priority. Recommended management include in particular stand thinning in order to reduce competition for water and re-introduction of resprouting hardwood species to prom...
