How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Dans la pessière noire à mousse de la forêt boréale, la succession forestière tend naturellement vers la paludification du sol. La paludification ou l'entourbement est l'accumulation de matière organique peu ou pas décomposée sur le sol minéral. Cette accumulation est due principalement à un bilan hydrique positif qui crée des conditions d'anaérobi...
Fire is considered the major disturbance in boreal forests. Nonetheless, in several areas logging has become the primary driver of forest dynamics. In many areas of the boreal forest, stands may undergo paludification (i.e. the accumulation of thick, poorly decomposed organic layers over the mineral soil) in the prolonged absence of fire, which red...
Abstract: Ecosystem-based management advocates that forestry disturbances should aim to emulate natural disturbances to mitigate the landscape-level impact of forest management. This study compares the impact of clear-cuts followed by a prescribed burn (CCPB) with clear-cuts alone (CC) and current careful logging practices (CLAAG: “careful logging...
Paludification, the accumulation over the mineral soil of poorly decomposed organic matter mainly originating from Sphagnum spp., transforms black spruce (Picea mariana) boreal forests into forested peat-lands in the prolonged absence of fire, which diminishes forest productivity. High-severity wildfires reset this process by burning the soil organ...
AimsWhile treeline positions are globally correlated to growing season temperatures, seedling establishment, an important process of alpine treeline dynamics, is additionally controlled by regional-scale factors such as snow cover duration, desiccating winds and biotic interactions. Knowing that alpine treelines have shown contrasting responses to...
Background/Question/Methods Globally, alpine treeline positions are defined by temperature which has led to the assumption that treelines would rise in response to climate change. But recruitment above treeline is also controlled by local drivers which modulate the effect of climate. This study aims to measure the relative effect of abiotic (temp...
Background/Question/Methods Cone production is known to decrease with altitude due to low growing season temperatures, which reduces the developmental period available to cone buds at the alpine treeline. However, the microclimate experienced by individual plants differs from ambient air temperature: wind has a direct negative effect on plant mic...
For the ecological integrity monitoring program of Mingan Archipelago National Park Reserve, we seek to monitor the use of reproductive site of five marine birds species: Little penguin, Atlantic puffin, Black guillemot, Common mure and Black legged kittiwake.
