1. Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support
Abstract : Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve.

2. Boreal Forest Wildfire in a Changing Climate
Abstract : The boreal region contains 40% of the earth’s carbon (C) that is stored in vegetation and soils with its forests accounting for almost 30% of the terrestrial C sink. Boreal forests are experiencing some of the most rapid rates of climatic warming and increases in fire activity, threatening to release large amounts of their dense C reserves to the atmosphere.

3. Microclimate at range margins : Consequences for boreal forest understory species
Abstract : A warmer climate will shift species distributional range margins poleward, but near-ground microclimates may modify these shifts. Cold-adapted northern species at their rear edge may survive locally in microrefugia with a colder microclimate, and warm-adapted southern species at their leading edge may colonize stepping stone habitats with a warmer microclimate.

4. Monoterpenes from the boreal coniferous forest : their role in atmospheric chemistry
Abstract : The goal of this work has been to increase our knowledge of the role of the monoteipenes emitted by the boreal coniferous forest in atmospheric chemical processes. To this end, measurements of air concentrations and emission rates have been made in forests of Scots pine (Pinus sylvestris) and Norwegian spruce (Picea abies) at 4 sites throughout Sweden, during the summers of 1989 and 1990.

5. Explaining temporal variations in soil respiration rates and delta13C in coniferous forest ecosystems
Abstract : Soils of Northern Hemisphere forests contain a large part of the global terrestrial carbon (C) pool. Even small changes in this pool can have large impact on atmospheric [CO2] and the global climate. READ MORE
