DESCRIPTION
The use of synthetic pesticides to control harmful organisms in agriculture and forestry has detrimental effects on the environment and human health; biocontrol represents an unequivocal alternative that is effective, sustainable and economical. It consists of using living organisms as “natural warriors” to reduce populations of undesirable insects.
OBJECTIVES
The Chair’s most original achievements during the past year include:
Moreover, in order for biocontrol to be adopted increasingly as a sustainable alternative to pesticides, it must be demystified and promoted among political leaders, users and the general public. Jacques Brodeur has pursued this objective in several domains, including as president of the International Organization for Biological Control.

DESCRIPTION AND OBJECTIVES
We have entered the “Anthropocene”: a period characterized by the Earth’s sixth major species extinction, driven by human activities. However, we are ill-equipped to predict changes in biodiversity and the consequences of those changes for ecosystem functioning. De plus, ces changements opèrent beaucoup plus rapidement que notre capacité à les détecter, ce qui rend difficile la priorisation des actions de conservation.
Furthermore, these changes greatly outpace our ability to monitor them, which makes it difficult to prioritize our conservation actions. They are trying to better understand and predict changes in plant biodiversity and the corresponding consequences at the ecosystem level by studying the morphological and physiological adaptations of plants – called “functional traits” – in changing environments.
Étienne Laliberté and his team are also studying the remarkably similar yet unique way that every plant species interacts with solar radiation, caused by subtle differences in the chemical make-up of their leaves. Such species-specific “spectral signatures” provide the foundational data that is needed for high-resolution remote sensing of plant biodiversity.
ACHIEVEMENTS
By unravelling the links between plant evolution, functional traits, and leaf spectral signatures, Laliberté’s research will shed new light on the causes and consequences of changing plant biodiversity, and pave the way for the creation of a global plant biodiversity observatory based on remote sensing of plant functional traits.
