  2. 1. Acclimation of boreal Norway spruce to climate change: Empirical and modelling approaches

    Author : Shubhangi Lamba; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; Climate change; Acclimation; MAESTRA; Whole Tree Chamber;

    Abstract : The findings of this thesis have important implications for the projections of future carbon and water fluxes for the boreal region. The observed boreal longterm acclimation responses of respiration and stomatal regulation differ from those of most temperate regions. READ MORE

  4. 2. Surface energy exchange and land-atmosphere interactions of Arctic and subarctic tundra ecosystems under climate change

    Author : Christian Stiegler; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface energy exchange; Arctic and subarctic tundra; climate change; permafrost; eddy covariance; snow cover; micrometeorology;

    Abstract : The surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. READ MORE

  5. 3. Land-atmosphere exchange of carbon in a high-Arctic wet tundra ecosystem

    Author : Torbern Tagesson; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon; methane; carbon dioxide; climate change; Arctic; NDVI; NDWI; micrometeorology; remote sensing; chamber; tundra;

    Abstract : Arctic ecosystems play a key role in the terrestrial carbon (C) cycle, but spa-tially explicit data on the C exchange is scarce in these remote areas. The global warming is especially dominant in the Arctic, and these areas are vul-nerable to climate change. READ MORE

  6. 4. Peatlands at a Threshold: Greenhouse Gas Dynamics in a Changing Climate

    Author : Magnus Lund; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chamber; greenhouse gas; nitrous oxide; methane; carbon dioxide; carbon; bog; Peatland; mire; eddy covariance; nitrogen; phosphorus; fertilization;

    Abstract : To be able to predict the strength of climate change and its consequences for mankind, it is of major importance to understand the contemporary greenhouse gas exchange of the terrestrial biosphere, as well as its response to changes in climate. To achieve such understanding both descriptive studies and manipulation experiments are required. READ MORE

  7. 5. Process based Modelling of Chemical and Physical Aerosol Properties Relevant for Climate and Health

    Author : Pontus Roldin; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas phase chemistry; aerosol dynamics; aerosol particles; climate; kinetic multilayer model; Fysicumarkivet A:2013:Roldin;

    Abstract : Atmospheric aerosol particles have substantial influence on climate and air quality. However, the anthropogenic influence on the atmospheric aerosol is still poorly known. This limits the understanding of past and future climate changes. READ MORE
