LabEx ARBRE aims to study the functioning and productivity of forest ecosystems. The main objectives are to understand their mechanisms, to predict their responses to global changes and to identify new avenues for the preservation and valuation of these ecosystems. One of the principle strengths of LabEx ARBRE is that it is structured to bring together a wide range of disciplinary expertise to understand how forest ecosystems function and to analyze their resources, from the molecular level to the landscape level.
Two years after its launch date, the major challenge for LabEx lies in developing the exchange interface between labs to take full advantage of a range of disciplines and scales essential to understanding the particularly complex functioning of forest ecosystems.
To best illustrated this cross-disciplinary success between the research units focused on the four thematic actions of LabEx ARBRE, this symposium will highlight the work of young and upcoming researchers; doctoral and post-doctoral students working with eight LabEx partner research units. It is designed to bring together the different disciplines and levels of research and to promote an exchange of ideas through as series of presentations, workshops and a scientific poster exhibition. In this spirit of open dialogue and exchange, a conference on “talking about science” and scientific mediation will be presented by Jean-Marc Galan (CNRS, Jaques-Monod Institute, University of Paris Diderot).
This two-day seminar will take place on 8-9 September, 2014 at the INRA center in Champenoux.
The deadline to submit presentation resumés has closed. Registration will stay open until 31 August. We will accept meal reservations up to 25 August.

Climate change and wood quality: what are the impacts? what are the management solutions?
Wood is the most abundant organic compound on the planet, it plays a major role in the functioning of trees and ecosystems and is essential resource for humans. Quality is an important aspect of wood as it affects how trees function and determines the final material properties. Today, a crucial issue for scientific research is therefore to understand and predict the impact of environmental changes on wood quality. This workshop proposes to address this issue by considering the following questions:
- How is wood used by trees, by the ecosystems and by humans?
- What is wood quality mean?
- What do we know about climatic influences on wood quality? What can we infer about future impacts of climate change on wood quality?
- How do we account for future changes expected in the forestry management?
Understanding tree-microbe interactions with a view to improved production and valorization
Wood represents one of the most abundant polymer resources of our terrestrial ecosystem. Tree-microbe interactions play an important role in the development of forest environments. As such, microorganisms can have positive effects on the production of forest biomass but also cause degradation. The roles vary among microorganisms and their direct interactions with forest ecosystems have an impact at the level of the wood, both relative to its production and its quality and thus induce an increase, or to the contrary, a depreciation of its value. Further, microorganisms, via their active interactions are or could be influential economic actors at the industrial level vis-a-vis developing new biotechnologies.
In this workshop we will discuss the following points:
- Interactions of forest ecosystems: Mycorrhizae and MHB, how can biomass be improved? How does phytopathologie effect production?
- Wood material: what are the preservation options to counter the effects of degraders?
- Industry: moving towards putting tree-microbe interactions to use? (depollution, enzymes, green chemistry,…)
Climatic changes and the phenomenon of species migration
Global climate change is one of the major problems of our time. We can anticipate rapid changes to both temperature and precipitation patterns. When faced with changes of ecological conditions, species can respond in three different ways: adapt, migrate or die off. Living organisms are have the capacity to evolve and adapt in response to changes in their environments, however this process takes time and changes induced by human activity, beginning with the industrial era, are extremely rapid on the evolutionary scale.
A growing number of ecological models have been developed since early 2000’s designed to study the phenomena of migrating forest species (plant and animal) in response to global warming. In a general sense, these models have predicted a shift in range to the North and towards higher altitutdes, and estimate that the potential for migration of plant species could be in the order of several hundred kilometers over the next hundred years. This phenomenon of migration will be more significant in boreal and temperate zones than in tropical zones.
The migration of the species under the influence of global warming would allow us, in the medium term, to address the challenges in biodiversity conservation and sustainable timber production. However, the overall success migrating forest species has been called into question, among other things, because of the fragmentation of the forest environments linked in particular to human development.
This workshop proposes to address this issue by addressing the following questions:
- What is the future for the species currently inhabiting our forests?
- What species will populate our forests in the future?
- What way (s) can forestry management methods and the environmental economy respond to the challenge of migrating plant species? How can these factors facilitate this migration?
