Drying Spring Accelerates Transitions Toward Pyrogenic Vegetation in Eastern Boreal North America Open
The ongoing climate change increases vegetation flammability in the boreal forests of eastern North America, leading to more intense and severe wildfires. Using palaeoecological data—including charcoal, pollen, chironomids and testate amoe…

Increasing spring dryness accelerates transitions toward pyrogenic vegetation in eastern boreal North America Open
Ongoing climate change is increasing vegetation flammability, intensifying fire activity in the boreal forests of eastern North America. This situation suggests a potential tipping point in fire regimes, raising critical questions about th…

Singleton-based species names and fungal rarity: Does the number really matter? Open
Fungi are among the least known organisms on earth, with an estimated number of species between 1.5 and 10 million. This number is expected to be refined, especially with increasing knowledge about microfungi in undersampled habitats and i…

Vegetation response in SE France to the millennial-scale climate variability of the last glacial period Open
Deep-sea pollen records from the Western European margin indicate that regional vegetation oscillated between open forest and steppe during the Last Glacial period (ca. 115-27 ka), in response to the millennial scale climate variability, s…

Future impacts of climate change on black spruce growth and mortality: review and challenges Open
Black spruce ( Picea mariana (Mill.) B.S.P.) is the dominant conifer species across a large part of North American boreal forests, providing many goods and services essential to human activities, and playing a major climatic role through t…
