Boreal forest is at the southern boundary of the moss-dominated tundra, which remains characteristically treeless because its spongy surface retains water that cannot drain away through the underlying permafrost. But as temperatures rise the permafrost recedes, (i)___ the (ii)___ of forest. Bla...
Approaching a thermal tipping point in the Eurasian boreal forest at its southern marginClimate change is increasing the intensity and frequency of extreme heat events. Ecological responses to extreme heat will depend on vegetation physiology and thermal tolerance. Here we report thatLarix sibirica, a...
Improved growing conditions can also speed up forest recovery following disturbances, such as wildfires or timber logging, and may facilitate forest expansion in the north. In contrast, at the southern boreal distribution boundary, boreal forests may become increasingly stressed as climate change ...
But for most of the migrants, these parks are just a rest stop after crossing those big stretches of water. Their destination may be much further north:the boreal forest. What is “boreal” forest? The boreal forest is vast. One of the largest ecosystems in the world, it encircles the g...
Tree species diversity is essential to sustaining stable forest ecosystem functioning. However, it remains unclear how boreal tree species diversity has changed in response to climate change and how it is associated with productivity and the temporal sta

The exchanges of carbon dioxide (CO2), water vapor, and energy were measured nearly continuously since 1996 over a mixed mature transition forest at the Borden Forest Research Station, in southern Ontario, Canada. Borden Forest, one of the longest running flux towers in North America, is ...
We described the early changes in understorey species composition after gap formation and assessed some of the factors responsible for higher resistance to disturbance. 2 At six sites, in the southern boreal forest of north-western Quebec, representing a successional gradient after fire, trees were ...
the drier southern margins of Eurasian boreal forests28. Spatially-contrasting responses of forest growth to warming have also been detected at mid-high latitudes over the Northern Hemisphere12,18,29. Importantly, IPCC forecasts remarkable increases in temperature across boreal Eurasia throughout the ...
Aerosol formation and subsequent particle growth in ambient air have been frequently observed at a boreal forest site (SMEAR II station) in Southern Finland. The EU funded project BIOFOR (Biogenic aerosol formation in the boreal forest) has focused on: (a) determination of formation mechanisms of...
