Introduction
I am a professor at the Forest Research Institute in the Université du Québec en Abitibi- Temiscamingue (UQAT). My research is focused on the impact of climate change on forest ecosystems using modelling approaches to provide decision management tools to mitigate their effects in boreal forests. My background is focused silviculture developing experimental treatments to reach the sustainable management in boreal forest, studding the growth, mortality, regeneration and vegetation responses.

Thesis
Full-text available
Canada possesses the third largest forest cover in the world (347 MHA), and of the forest area that is harvested, 93% of logging is done by clear-cut methods. These cutting methods have serious impacts in terms of the simplification of stand structure, biodiversity, and the sustainability of forest ecosystems. Boreal forest ecosystem management pro...

In scenarios of future climate change, there is a projected increase in the occurrence and severity of natural disturbances inboreal forests. Spruce budworm (Choristoneura fumiferana)(SBW) is the main defoliator of conifer trees in the North American boreal forests affecting large areas and causing marked losses of timber supplies. However, the imp...

Forest regeneration is a key element in achieving sustainable forest management. Partial harvest methods have been used extensively in temperate broadleaf and mixedwood ecosystems to promote regeneration on poorly stocked sites and to maintain forest composition and productivity. However, their effectiveness in promoting conifer establishment has y...

Natural disturbance is one of the major topics in forest ecology. However, most paleoecological studies have only considered the influence of wildfire as an agent of disturbance, with fire history based primarily on the use of charcoal as a proxy for fire events. The frequency and intensity of insect outbreaks and their effect on the forest landsca...

Forest ecosystem management heads towards the use of partial cuttings. However, the wide variation in growth response of residual trees remains unexplained, preventing a suitable prediction of forest productivity. The aim of the study was to assess individual growth and identify the driving factors involved in the responses of residual trees. Six s...

We present a broad class of semi-parametric models for time series of random sums of positive variables. Our methodology allows the number of terms inside the sum to be time-varying and is therefore well suited to many examples encountered in the natural sciences. We study the stability properties of the models and provide a valid statistical infer...

Forest harvesting and fire are major disturbances in boreal forests. Forest harvesting has modified stand successional pathways, which has led to compositional changes from the original conifer-dominated forests to predominantly mixed and hardwood forests. Boreal fire regimes are expected to change with future climate change. Using the LANDIS-II sp...

Sapwood characteristics, such as sapwood area as well as thermal and hydraulic conductivity, are linked to species-specific hydraulic function and resource allocation to water transport tissues (xylem). These characteristics are often unknown and thus a major source of uncertainty in sap flow data processing and transpiration estimates because bulk...

Research in boreal ecology is essential for the development of sustainable forestry and practices adapted to climate change. It is in this perspective that the MRC Abitibi and UQAT have joined forces to create the Groupe de recherche en écologie de la MRC Abitibi (GREMA). GREMA's research program is structured around three themes: the silviculture...

The boreal forest is the second largest terrestrial biome in the world, covering 14 million km2 spread over a circumboreal forest belt that represents about 25% of the world's forest. Currently, two-thirds of this area is managed for timber production and produces 37% of the world's timber, making logging a central economic driver for boreal countr...

Partial harvest is considered as a promising alternative to clearcutting system to integrate ecological, economical, and social objectives into silvicultural planning. Logging activity alters habitat conditions for plant and microbial communities in the understory and consequently influences ecosystem processes such as nutrient cycling. Even with t...

Cyanobacteria are the Earth’s oldest photoautotrophs and provided the level of oxygen we currently have today. However, when they overgrow and form a bloom, they cause ecological degradation and sometimes they produce toxins that become life threatening. This phenomenon is “harmful algal blooms” and is linked with eutrophication, and water temperat...
