Actinobacterial communities of boreal forest soil and lake water are rich in mycobacteria

, 2006
The actinobacterial communities present in two Finnish lakes and in the surrounding conifer forest soil were investigated using DNA based methods. The dominant actinobacteria in the soil were found to belong to genus Mycobacterium.

Limited overall impacts of ectomycorrhizal inoculation on recruitment of boreal trees into Arctic tundra following wildfire belie species-specific responses.

PLoS ONE, 2020
We tested whether post-fire seedling establishment of common boreal tree and expanding shrub species at treeline and in Arctic tundra is facilitated by co-migration of boreal forest mycorrhizal fungi.

Limnological characteristics of 56 lakes in the Central Canadian Arctic Treeline Region

Journal of Limnology, 2003
Measured environmental variables from 56 lakes across the Central Canadian Treeline Region exhibited clear limnological differences among subpolar ecozones, reflecting strong latitudinal changes in biome characteristics (e.g.

The Boreal Forest

, 1996
Contained within the Atlas of Canada Poster Map Series, is a poster which shows the location of boreal forest in Canada. The two sided poster graphically depicts the importance of the boreal forest as a dynamic system of shrubs, trees, herbs, mosses, micro-organisms, insects and animals interacting among themselves and with rock, soil, water and air ...

Sources of particulate organic nitrates in the boreal forest in Finland

, 2017
Organic nitrates (ON) are known to be present in secondary organic aerosol and act as a reservoir of nitrogen oxides, regulating the local and regional ozone and hydroxyl radical budgets. This work reports observations of particulate ON in Finnish remote

Dead standing pine trees in a boreal forest landscape in the Kalevala National Park, northern Fennoscandia : amount, population characteristics and spatial pattern [PDF]

, 2017
Background After their death, Scots pine trees can remain standing for decades and sometimes up to 200 years, forming long-lasting and ecologically important structures in boreal forest landscapes.

Forestry impact on water quality: a landscape perspective on dissolved organic carbon [PDF]

, 2013
Dissolved organic carbon (DOC) is a fundamental variable defining boreal stream ecosystems. In this thesis the impact of forestry practices that are commonly performed in the boreal regions of Scandinavia for stream water quality were evaluated.

Adapting forest management to forest fires – some options to explore for the boreal forest

The Forestry Chronicle
The Canadian 2023 forest fire season has been of such magnitude that it forces us to think deeply about forest management as it is currently practiced in the Canadian boreal forest. As similar events are likely to recur in upcoming years, we must reflect

Remote Sensing Techniques in Monitoring Post-Fire Effects and Patterns of Forest Recovery in Boreal Forest Regions: A Review

Remote Sensing, 2013
The frequency and severity of forest fires, coupled with changes in spatial and temporal precipitation and temperature patterns, are likely to severely affect the characteristics of forest and permafrost patterns in boreal eco-regions.

Modeling the Impacts of Boreal Deforestation on the Near-Surface Temperature in European Russia

Advances in Meteorology, 2013
Boreal deforestation plays an important role in affecting regional and global climate. In this study, the regional temperature variation induced by future boreal deforestation in European Russia boreal forest region was simulated based on future land ...
