Climate change has resulted in a widespread increase in primary productivity in northern regions. This “greening” can alter terrestrial ecosystems dynamics and trigger positive climate feedbacks but often exhibits spatial heterogeneity. Few studi

Progression of a spruce budworm outbreak over seven years is associated with increased soil nutrient fluxes and availability and improved foliage quality in surviving host trees. This could create a bottom-up feedback that sustains an insect outbreak

Altered temperature and precipitation regimes associated with climate change generally result in improved conditions for plant growth. For Arctic and sub-Arctic ecosystems, this new climatic context promotes an increase in primary productivity, a phe

Climate warming at high latitudes has contributed to the growing interest in shrub tree-ring analysis. Shrub architecture presents new challenges for dendrochronology, such as the seemingly lower and inconsistent climatic sensitivity of stems vs. roo

La ville est souvent décrite comme le lieu de la centralité maximale. Les réseaux matériels et immatériels convergent vers celle-ci alors que la densité généralement forte d’activités, de personnes et d’infrastructures physico-spatiales

Climate warming-driven early leaf-out is expected to increase forest productivity but concurrently increases leaf exposure to spring frosts, which could reduce forests' net productivity. We hypothesized that due to their damaging effect on buds, spri

Le Québec, l’ensemble du Canada, voire l’Alaska ou la Russie, contiennent de vastes espaces nordiques inhabités. Cette affirmation, qui tombe sous le sens pour la majorité des Québécois et de leurs voisins anglophones, est pourtant lourde d

Abstract Canada’s boreal forest represents an important contributor of the world’s wood supply industry. However, maintaining or increasing productivity of the boreal forest may be challenging in areas dominated by forested peatlands. Moreover, s

The rise in ore demand over the last two decades has fostered the opening of several mines in northern Quebec and Labrador. As a result, many new mining sites have emerged, in addition to the Hydro-Québec dams. The previous mining booms had led to t
