Properties of Arctic lakes vary depending on the type of soil, major sources of water, size of the lake, elevation and climatic conditions among others. We studied 35 lakes of...

From August 25 to September 1, 2022, fieldwork was conducted in Old Crow Flats, Yukon (Canada) to study thermokarst lake and drained basin dynamics. As part of this work,...

A network of temperature and humidity sensors was deployed near Yellowknife, Canada to establish 28 distinct study sites reflecting landscape variability. The field campaign was...

The number of glacial lakes is rapidly increasing with glacial retreat in the Canadian High Arctic, yet very little is known about the biology of these aquatic environments....

Dissolved organic matter (DOM) leaching from thawing permafrost may have feedback effects on climate if it is efficiently mineralized into greenhouse gases (GHG). Yet, many...

Lemmings are an essential link of the Arctic food web as they are the main prey of many predators inhabiting these regions. These small rodents exhibiting cyclic fluctuation of...

Northern terrestrial ecosystems are undergoing rapid transformation, potentially affecting the chemistry and microbial community structure in rivers flowing through them. From 2...

Establishing new ecological baselines and initiating monitoring schemes on Arctic vegetation are critical to monitor, predict, and manage current and future impacts of climate...

High Arctic lakes are important sentinels of ongoing climate changes, although many details about their functioning remain to be fully understood. Since 2017, the Stuckberry...

Data are from the Tantaté ecological reserve, Quebec, Canada. It contains data from air and ground temperatures, solar radiation, wind speed and direction. The available...

Data are from the Robert-Bourassa Reservoir region, Quebec, Canada. It contains data from air and ground temperatures, air humidity, solar radiation, wind speed and direction...

Permafrost thawing mobilizes large quantities of organic carbon that was sequestered in Arctic regions over the last glacial cycle. Processes involved in the oxidation and...

Foxes are strongly dependent on dens for parturition and rearing of cubs. Due to the shallow permafrost-free layer in most of the arctic fox’s range, new dens are rarely dug and...

Nests are mainly found through systematic searches of a 4.5 km2 core area near our main field station from early June to early July since 2005. Nests are also found...

While most ecological studies focus on the impact of climate change on some populations or species, broader, ecosystem-based information is needed to better predict the future...

Frozen tundra soils hold one of the Earth’s largest pools of organic carbon. With global warming, permafrost is thawing at an accelerated rate, promoting the formation of...
