Dans le contexte des changements climatiques actuels, de nombreux cas de dépérissement de la végétation sont observés à travers le monde. Les écosystèmes forestiers méditerranéens français, bien qu'adaptés aux périodes de sécheresse, souffrent aussi de l'augmentation de la fréquence et de l'intensité de ces épisodes. Les objectifs de cette étude on...

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. Here we e...
In contrast to plant-animal interactions, the conceptual framework regarding the impact of secondary metabolites in mediating plant-plant interference is currently less well defined. Here, we address hypotheses about the role of chemically-mediated plant-plant interference (i.e., allelopathy) as a driver of Mediterranean forest dynamics. Growth and...
Management strategies, using thinning combined or not combined with underplanting, have been tested in experimental forests of Spain and southern France to promote growth, recruitment and increase their resilience. In dry and fire-prone areas of southern Spain and France, Pinus halepensis forests were thinned at different levels and hardwood specie...

KeymessagePith diameter is a good parameter to solve dating architecture problems.AbstractPlant architecture can be used to study plant development retrospectively thanks to time-dependent morphological markers, particularly those corresponding to the winter break in temperate regions. The Aleppo Pine and the Turkish Pine are polycyclic species, th...
Context: Developing silvicultural methods to help Mediterranean forests adapt to climate change is of high importance. Introducing resprouting hardwood species below pine stands is expected to promote diversity and resilience of these stands, particularly to forest fires. Aims: To examine how the intensity of pine thinning influences understory mic...
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...

The objectives of this study were to describe and quantify Aleppo pine aerial primary growth processes and to assess their relationships with climate. Primary growth (branch length growth, branching rate, polycyclism, needle number and size, fruiting), i.e. crown development and reproduction, was reconstructed for the last 16 years in Mediterranean...
Question: How do forest microhabitats impact seasonal microclimate conditions and phenological seedling strategies in two co-occurring Mediterranean Quercus species with different leaf habits? Location: Pinus halepensis woodlands, Provence, SE France. Methods: Ninety sets of three acorns of Quercus ilex (evergreen) or Quercus pubescens (winter-deci...
