Introduction
I am a plant functional ecologist. I am focusing on impacts of global change on tree growth and survival, forest dynamics and woody species distribution range. I am also studying the effects of climate change on water circulation in soil–plant–atmosphere continuum.

Article
Full-text available
Drought-induced cavitation in plants is caused by low soil water availability and/or high atmospheric water demand, resulting in the disruption of water columns in plant conduits. This phenomenon leads to the obstruction of sap flow when the conduit elements become embolized due to a strong negative xylem water potential. The vulnerability curve (V...
Article
Full-text available
The future climate of northern temperate forests is projected to be drier and warmer by the end of this century. As a result, more drought-induced forest dieback events are anticipated in northeastern North America, and assessing the vulnerability of dominant tree species to drought is critical for understanding the future composition of these fore...
Article
Full-text available
This data article describes datasets of plant community composition, dendrometric measurements, quantity and quality of snags of humid boreal stands (Quebec, Canada) from an experiment comparing silviculture scenarios of increasing intensity: (i) careful logging around advance growth (CLAAG); (ii) CLAAG followed by pre-commercial thinning; (iii) pl...
Article
Full-text available
Climate change is projected to increase fire severity and frequency in the boreal forest, but it could also directly affect post-fire recruitment processes by impacting seed production, germination, and seedling growth and survival. We reviewed current knowledge regarding the effects of high temperatures and water deficits on post-fire recruitment...
Article
Full-text available
Sustainable forest management implies successful regeneration after disturbances. Low N availability and competition can, however, limit tree establishment in boreal ecosystems. To develop silviculture strategies that maintain productivity in such context, we established a field trial in northern Québec, Canada. We evaluated if a companion N2-fixin...
Article
Full-text available
Vegetation management is required so that plantations present expected yields, but its impacts depend on the time of application. Our objective was to evaluate the effect, after 1520 years, of delaying the application of a mechanical release treatment in Picea glauca and Picea mariana plantations, relative to the timing prescribed based on operatio...
Article
Ecosystem-based management, now a dominant forestry paradigm, implies reducing the gap between variability of natural and managed forests (i.e. ecological distance) to reconcile ecological issues with production of socioeconomic services. Here, we tested whether a trade-off exists between conserving key ecosystem attributes of natural forests and m...
Article
The enemy release hypothesis is frequently invoked to explain invasion by non-native species, but studies focusing on the influence of enemies on natural plant range expansion due to climate change remain scarce. We combined multiple approaches to study the influence of plant-enemy interactions on the upper elevational range limit of sugar maple (A...
Conference Paper
Full-text available
Vegetation management is crucial to meeting the objectives of forest management, especially those associated to plantations. However, vegetation management treatments are among the silvicultural tools that show the greatest potential for the artificialization of natural forests. In Quebec, a new forest regime centered on ecosystem management has be...
Article
Full-text available
Populations growing at the warm margins of the species' range are more prone to experience higher water stress compared to populations inhabiting the core of their distribution. Thus, assessing tree vulnerability to drought is crucial to improve prediction of forest mortality and species range limits. We quantified the abundance of two oak species...
Article
Full-text available
A major unknown in the context of current climate change is the extent to which populations of slowly migrating species, such as trees, will track shifting climates. Niche modelling generally predicts substantial northward shifts of suitable habitats. There is therefore an urgent need for field-based forest observations to corroborate these extensi...
Article
Full-text available
Hydraulic failure is one of the main causes of tree mortality in conditions of severe drought. Resistance to cavitation is known to be strongly related to drought tolerance and species survival in conifers, but the threshold of water-stress-induced embolism leading to catastrophic xylem dysfunction in angiosperms has been little studied. We investi...
Thesis
Full-text available
Tree distribution could be highly affected by climate change. Results of paleogeographic studies showed that tree distribution ranges have already shifted with past climate changes. These data are currently used to model the evolution of species distribution in response to global warming. However, the ecological context in which species have to cop...

QuestionsThe objectives of this study were to examine altitudinal shifts in tree species distributions over one decade to quantify the potential for tree migration. LocationSpain. Methods We analysed presence-absence data using two successive surveys of the Spanish Forest Inventory in five Fagaceae tree species (two temperate: Fagus sylvatica and Q...
